Inspection

Check the pads for excessive wear, discs for run out and wear, and calipers for fluid leakage.

Front Brake

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.
Front brake disc thickness Standard : 23 mm (0.906 in) Service Limit : 21 mm (0.827 in) Deviation: Less than 0.005 mm (0.0002 in)

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: 10.5 mm (0.413 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 (0.0016 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.

Rear Brake

Rear 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: 10 mm (0.393 in) Service limit: 8.4 mm (0.331 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.

Rear 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: 10 mm (0.394 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.

Rear 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: 0.05 mm (0.0020 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.

Replacement

Front brake pads
