Servo Brake Mechanism Repair
In vertical (Z-axis) applications the servo motor brake is a safety element. A brake that will not release stops the motor from turning; a brake that will not hold causes the axis to drop and creates a serious safety risk. We overhaul the brake mechanism and restore safe braking.
Brake Fault Symptoms
- Brake will not release: motor shaft locked, not turning
- Brake will not hold: axis slips/drops when stopped
- Burnt or short-circuited brake coil
- Friction noise from the brake
Our Brake Repair Process
We inspect and, where needed, replace the brake coil and lining, re-adjust the air gap and run release/hold tests with 24V supply. See our services.
Why Brake Repair Is Critical
A brake that will not hold on the Z-axis can damage the workpiece, machine and operator, so we test under real supply conditions.
Frequently Asked Questions
The brake will not release and the motor will not turn — why?
The brake coil may not be energised or the lining may be stuck. It is solved by coil and air-gap checks.
The brake will not hold and the axis slips — can it be repaired?
Yes. It is caused by lining wear or coil failure and fixed by part replacement and adjustment.
The shaft will not turn by hand — is the brake the fault?
Often the shaft stays locked because the brake will not release; brake repair solves it.
Is there a warranty after repair?
Yes. The brake mechanism is delivered under warranty after testing.
