Measurement of thickness of overlays of forward disk brakes
Large brake overlays of forward disk brakes often maintain a run more than 50 000 km. Control of thickness of slips is of great importance for safety, – easily "forget" about brakes, in view of such high hodimost of slips, – as in Audi A4 is not present to more alarm bulb of wear of brake slips as it was in the previous models:

Measurement of a brake slip on brakes of a forward wheel:
1 – slip material;
2 – the bearing plate from metal. |
|
|
- The minimum thickness of a slip makes 7 mm, including the bearing plate. The bearing plate – a metal detail on which the slip is pasted – has thickness about 5 mm, at the same time material of a direct slip has to have the minimum thickness of 2 mm.
- At fluent control with the taken-off cap of a wheel light a lamp in an opening of a rim and estimate slip thickness.
- More exact control at the removed wheel.
- Apply a ruler to a slip and measure, do not forget about a brake slip on inside!
