1.
Remove all rust and contamination from the disc surface, and then measure the disc thickness at 8 positions at least.
Rear brake disc thickness
Standard value : 10.0 mm (0.39 in)
Limit : 8.4 mm ( 0.33 in)
Remove all rust and contamination from the disc surface, and then measure the disc thickness at 8 positions at least.
Rear brake disc thickness
Standard value : 10.0 mm (0.39 in)
Limit : 8.4 mm ( 0.33 in)
Thickness variation should not exceed 0.01 mm (0.0004in) (circumference) and 0.01 mm(0.0004 in) (radius) at any directions.
If wear exceeds the limit, replace the discs and pad assemblies for left and right of the vehicle.
Check the pad wear. Measure the pad thickness. replace it if it is less than the specified value.
Pad thickness
Standard value : 10.0 mm (0.39 in)
Service limit : 2.0 mm (0.0787 in)
Check that grease is applied, to sliding contact points and the pad and backing metal for damage.
Place a dial gauge about 5mm (0.2 in) from the outer circumference of the brake disc, and measure the run out of the disc.
Brake disc run out
Limit : 0.05 mm (0.0020 in) or less
If the run out of the brake disc exceeds the limit specification, replace the disc, and then measure the run out again.
If the run out does not exceed the limit specification, install the brake disc after turning it and then check the run out of the brake disc again.
If the run out cannot be corrected by changing the position of the brake disc, replace the brake disc.
