Remarks
|
Scratches, rust, saturated lining materials and wear
|
- If the vehicle is not driven for a certain period, the sections of the discs that are not in contact with lining will become rusty, causing noise and shuddering.
- If grooves resulting from excessive disc wear and scratches are not removed prior to installing a new pad assembly, there will momentarily be inappropriate contact between the disc and the lining (pad).
|
Run-out or drift
|
Excessive run-out or drift of the discs will increase the pedal depression resistance due to piston knock-back.
|
Change in thickness (parallelism)
|
If the thickness of the disc changes, this will cause pedal pulsation, shuddering and surging.
|
Inspection items

Overheating and improper handling while servicing will cause inset or warping.
