Front Brakes – Judder and Vibration
Customer complains of judder and vibration of the steering wheel when braking.
This is caused by seized brake pads.
In case of customer complaint the free movement of the brake pads has to be checked.
If a sticking condition of the brake pads is found the brake pads should be removed. Clean the lateral guide and side surfaces of the brake pads with a suitable tool.
Lubricate the lateral guides with special lubricant (details below).
Note: Make sure that the friction surface is not contaminated with the special lubricant
A replacement of the brake discs or brake pads is only necessary if the “Disc Maximum Allowable Assembled Lateral Run-out – with Wheel Attached” is exceeded (see TIS2Web info) and steering wheel vibrations or brake juddering is detected.
