If you manage a building, brakes rarely cross your mind until you feel a jolt, smell hot friction, or take a call that a lift is stuck between floors. We think about them constantly. And from what we see on site, one of the strongest indicators of a safe, smooth, compliant lift is the condition and testing of its brakes. This piece explains how the brake chain actually keeps passengers safe, why routine maintenance tends to matter more than any headline upgrade, and what practical steps you can take this week to reduce risk, downtime and cost.
We’re Future Lift Services. We maintain, repair and modernise lifts across London and the South East. We’re independent, so we specify what suits each site rather than what a single manufacturer happens to sell. Our lift engineers attend around the clock for emergency lift call out, and our maintenance is built around lift safety, compliance and reliable operation.
Safety Mechanisms You Can Rely On
When most people picture “brakes”, they imagine a single component. In a lift, safety comes from a chain of overlapping safety systems. If one element doesn’t act, the next is designed to catch it. That layering is the whole point.
Here’s the brake chain we check and prove during regular inspections:
Machine brake on the motor or traction sheave. This is the day-to-day brake that holds the elevator car at floor level when the doors open. On most modern elevators it’s an electromagnetic brake, held open by electrical power and applied by springs when power is removed. In the event of a power loss, the springs engage and the brake clamps the brake disc or drum to stop the drive.
Safety gear on the car or counterweight. These are the safety brakes that grip the guide rails when triggered by the overspeed governor. Progressive types are designed to apply gradually, so the elevator car decelerates rather than stopping abruptly.
Overspeed governor. A mechanical speed monitor, typically driven by its own rope. If the lift exceeds its trip speed beyond normal speed and the controller hasn’t corrected it, the governor trips and actuates the safety gear to stop the elevator.
Buffers in the pit. Pit buffers are the final layer at the bottom of the elevator shaft, absorbing energy if the car travels below its lowest landing.
Redundancy in the controls. Drive limits, door circuits and load control work alongside the brake chain to help prevent uncontrolled movement or overspeed.
To give a sense of how this plays out in practice: on a recent LOLER inspection of a mixed-use building, our engineer noticed the machine brake was taking slightly longer than expected to grab after the controller dropped power. Investigation pointed to contaminated brake pads and a tired return spring. We replaced the pads, reset the spring force and repeated braking system testing with the client present.
The result was cleaner stops, less slip at the traction sheave, and an end to the nuisance door re-levelling alarms. That’s lift safety delivered through straightforward, timely maintenance rather than anything dramatic.
How the Main Brake Works
It helps to follow the chain of motion. The electric motor turns the drive sheave, which moves the suspension ropes, which in turn move the car and counterweight. To stop the elevator, the controller removes power from the electromagnetic brake coil. With the electromagnetic force no longer holding it open, the springs push the brake shoes or calipers onto the brake disc or drum, and the resulting friction stops the drive.
A few points, kept simple:
Electromagnetic brakes are designed to be fail-safe. They engage when electrical power is removed, whether that’s a normal stop or a power failure. In the event of a power loss, the brake applies and holds the car.
Friction surfaces matter. Brake pads and brake shoes need to be clean, within thickness tolerance and free of glazing. Oil contamination — from a nearby bearing, say — can noticeably extend stopping distance, which is one reason we treat any sign of contamination seriously.
The brake has to hold. Once an elevator stops, the machine brake should hold position without creep, including under rated load. Confirming that is part of our LOLER compliance checks and passenger lift servicing routines.
Actuation varies by equipment. The most widely used type in traction lifts is the spring-applied electromagnetic brake. Some legacy equipment relies on mechanical linkages and levers, and certain goods lifts use hydraulic assist — sometimes via a brake cylinder — to help generate additional braking force. The principle is consistent: controlled friction creates the braking force needed to stop the elevator and hold it still.
On site we measure stopping performance, check the brake air gap, confirm the response time, and verify that the elevator stops within its expected stopping distance and stays level. If the elevator car moves after a stop command, or slips a few millimetres off floor level, that’s usually a brake conversation rather than a door one.
Emergency Braking That Protects Passengers
Emergency systems exist for the uncommon situations where routine control can’t bring the car to a clean stop.
Governor and Safety Gear for Overspeed
If a fault drives the car toward overspeed, the governor trips. That mechanical trip drives a linkage into the car safety gear, and progressive safety gears clamp the guide rails to stop the elevator with controlled deceleration. This is intended to prevent free fall and uncontrolled movement, and it’s a core requirement within standards such as BS EN 81-20 and BS EN 81-50, which set out how lifts of this kind should be designed and tested.
Machine Brake in Abnormal Situations
The machine brake also acts during an emergency stop. If a contactor drops out or the controller detects a fault, power is removed from the brake coil and the springs apply. Many installations use dual independent brake modules, and that redundancy is deliberate: if one module fails to engage, the other should still stop the elevator.
Dynamic and Regenerative Braking
Some drives use dynamic braking, converting motor energy to heat in a resistor to slow the car, or regenerative systems that feed energy back to the supply. These are control methods, not safety brakes. They help deliver a smooth stop; the mechanical brakes then engage to hold the car.
Lift Maintenance That Keeps Brakes Honest
Safe stops don’t happen by chance. They come from planned lift maintenance and checks that are reliably, almost tediously, consistent.
What we test, and why:
Brake air gap. Too large and the brake takes longer to engage; too small and it can drag and overheat.
Brake pad and shoe wear. Thin linings reduce braking force and can glaze. We measure, record and replace before limits are reached.
Spring force and condition. Springs lose tension over many cycles and with environmental factors, so we check engagement force and replace sets together.
Coil resistance and insulation. Coils outside specification may fail to release cleanly or fail to pull in consistently, and either undermines reliable operation.
Clean running surfaces. Oil or dust on a brake disc or drum reduces friction, so we clean, deglaze and re-test the stops.
Controller timings. We verify that the brake drop-out timing stays in step with the drive ramp, which avoids hard stops and keeps the ride smooth.
You may have come across the “30/30/30 rule for brakes” online. That’s a road-vehicle rule of thumb and it doesn’t apply to lifts. Lift braking is governed by specific lift safety features, standards and measured tests set out in BS EN 81 and checked through LOLER examinations. If anyone quotes 30/30/30 for a lift, it’s worth questioning.
Lift Safety Compliance and the Standards That Matter
For UK sites, the compliance picture comes down to a few essentials:
LOLER inspection. Lifts used by people at work must undergo a thorough examination by a competent person — at least every six months for passenger lifts under Regulation 9 of LOLER 1998 (HSE). We help coordinate inspection schedules, prepare the equipment and close out any actions promptly.
BS EN 81-20 and BS EN 81-50. These are the principal standards for lift design and testing in the UK and Europe, covering construction and installation alongside the design rules, calculations and component tests (BS EN 81-20:2014). Among many requirements, they address fail-safe elevator brakes and progressive safety gear, and they expect brakes to stop and hold under rated load.
On-site records and lift safety certification. Your records should show regular inspections, lift service contracts, braking system testing results, parts replaced and emergency protocols. We provide clear reports you can pass straight to your insurer.
Lift safety awareness. We brief building teams on simple checks and emergency procedures, including safe passenger communication, power isolation, and how to request an emergency lift call out without risking further damage.
Compliance isn’t really about paperwork. It’s evidence that the systems you depend on will safely stop, hold and protect passengers when something goes wrong. We aim to walk you through each item, agree priorities together, and keep the jargon to a minimum.
Choosing, Repairing and Modernising Brakes
Different sites call for different brake solutions, and here’s roughly how we think about it when specifying lift repair or modernisation:
Disc-type brakes. Common on medium- to high-speed traction machines. A caliper clamps a brake disc on the motor or traction sheave. Good heat dissipation and consistent performance.
Drum-type brakes. Internal brake shoes act on a rotating drum. Common on legacy equipment — effective, but they need careful adjustment and close attention to wear.
Caliper disc brakes. Two opposing pads clamp the disc. Often chosen where higher braking force is needed in a compact space.
Electromagnetic brakes. The most widely used type in lift motors. Spring-applied and power-released, they sit at the heart of modern lift stopping and holding.
Hydraulic assist or hydraulic brakes. Found in some heavy-duty applications and goods lifts, where they help generate higher braking force.
Mechanical brakes and linkages. Still in service in plenty of older plant rooms. Springs and levers provide fail-safe engagement, but they typically need more frequent attention.
Existing elevators can often be upgraded without replacing the whole machine. We frequently retrofit dual machine brake modules, swap worn friction materials for approved modern equivalents, and add monitoring to confirm position and engagement. These customised solutions are usually more cost effective than a full lift installation, and they often deliver a strong lift safety improvement for the money spent.
Comparison: Braking System Types and Where They Fit
| Braking system type | Where you’ll see it | How it stops | Strengths | Maintenance focus |
| External block brake (spring-applied electromagnetic) | Most traction lifts with an electric motor and traction sheave | Springs apply pads to a brake disc or drum when power is removed | Fail-safe by design, compact, reliable operation | Pad wear, air gap, spring condition, clean friction surfaces |
| Drum-type brake with brake shoes | Legacy traction machines | Shoes expand inside a rotating drum | Robust, familiar to many engineers | Shoe lining wear, drum glazing, linkage adjustment |
| Caliper disc brake | Higher-speed or higher-load applications | Calipers clamp both sides of a disc | Strong, predictable braking force | Pad thickness, caliper alignment, disc runout |
| Hydraulic-assisted brake | Heavier goods lifts | Hydraulic pressure augments spring force | Handles heavier loads well | Seal condition, fluid leaks, response timing |
| Dynamic braking (drive function, not holding) | Modern VVVF drives | Motor slows the car via a resistor or regen | Smooth deceleration, energy recovery | Resistor health, control logic; does not replace mechanical brakes |
Emergency Protocols Worth Having in Place
These are worth making standard across your sites:
- A clear passenger communication plan for entrapments, to keep people calm and informed.
- A single number for emergency lift call out, posted inside and outside the lift.
- A defined power isolation process, and clarity on who is authorised to use it.
- A short checklist for reception or facilities to note the time, car position and any unusual noises.
- A calendar of regular inspections — LOLER inspection, lift safety reviews and braking system testing — with signed records.
If you’d like templates, just ask. We’re happy to share what works across our portfolio.
Summary and Key Takeaways
- Brakes are a chain, not a single part. Machine brakes, safety gear, the governor and buffers work together to safely stop and hold the car.
- Electromagnetic brakes are designed to fail safe. Springs apply when power drops, so the system can stop the elevator even during power loss.
- Wear, contamination and timing cause most brake problems. Routine lift maintenance that measures air gap, pad thickness and timings helps prevent harsh stops and entrapments.
- Compliance protects people, and you. Plan your LOLER inspection, keep records, and check braking system testing against BS EN 81 requirements.
- Modernise where it matters first. Dual machine brakes, better friction materials and added monitoring often deliver the biggest practical gains on existing elevators.
- Have clear emergency protocols. Communication, a single call-out route and simple checklists reduce stress and risk for passengers and staff.

FAQs
What are the most important lift safety best practices for building managers?
Good lift safety management starts with consistency: schedule routine inspections, keep an eye on braking system components, and make sure mechanical components such as cables and the traction wheel are clean and correctly tensioned. Regular testing and clear records help reduce risk and support compliance.
How do lift safety innovations improve braking performance?
Newer lift technology — real-time brake monitoring, improved friction materials and dual redundant braking systems among them — can help braking system components respond more predictably under load. These new technologies tend to improve stopping accuracy and reduce wear on cables and other mechanical components, though the right choice still depends on the individual lift.
Which components are most critical in a lift braking system?
The key elements include the machine brake, overspeed governor, safety gear and supporting mechanical components such as cables and the traction wheel. Together they form a fail-safe chain designed to stop and hold the lift safely, even if one element doesn’t act as intended.
