Visual inspection of pad thickness
Fig. 6.43. Visual inspection of brake pad thickness
Check the thickness of the pads. To do this, lift the car, remove the wheel and look through the inspection hole in the cylinder body (Fig. 6.43).
- Minimum thickness of brake pads: 1mm.
- Wear limit: 2.0 mm.
Removal brake pads
Caution: When replacing brake pads, always replace the inner and outer linings and lining caps as a set.
Drain the brake fluid.
Remove the front wheel and temporarily secure the wheel rim with two nuts.
