Front brake disc thickness check
1. |
Check the brake pads for wear and fade. |
2. |
Check the brake disc for damage and cracks. |
3. |
Remove all rust and contamination from the surface, and
measure the disc thickness at 8 points, at least, of same distance (5mm)
from the brake disc outer circle.
Brake disc thickness
- Standard : 28 mm (1.10 in)
- Service Limit : 26.4 mm (1.04 in)
Deviation: Less than 0.005mm (0.0002in)
|
|
4. |
If wear exceeds the limit, replace the discs and pad assembly left and right of the vehicle. |
Front Brake Pad Check
1. |
Check the pad wear. Measure the pad thickness and replace it, if it is less than the specified value.
Pad thickness
Standard value: 11 mm (0.43 in)
Service limit: 2.0 mm (0.0787 in)
|
|
2. |
Check that grease is applied, to sliding contact points and the pad and backing metal for damage. |
Front brake disc runout check
1. |
Place a dial gauge about 5mm (0.2 in.) from the outer circumference of the brake disc, and measure the runout of the disc.
Brake disc runout
Limit: 0.04 mm (0.00157 in.) or less (new one)
|
|
2. |
If the runout of the brake disc exceeds the limit specification, replace the disc, and then measure the runout again. |
3. |
If the runout does not exceed the limit specification,
install the brake disc after turning it 180° and then check the runout
of the brake disc again. |
4. |
If the runout cannot be corrected by changing the position of the brake disc, replace the brake disc. |
1. |
Installation is the reverse of removal. |
2. |
Use a SST (09581-11000) when installing the brake caliper assembly. |
