Inspection

Rear Brake Disc Thickness Check

1.	Check the brake pads for wear and fade.

2.	Check the brake disc for damage and cracks.

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.

Rear Brake disc thickness

Standard: 10 mm (0.39 in)

Service limit: 8.4 mm (0.33 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.

Rear Brake Pad Check

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 (0.393 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

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: 0.03 mm (0.00118 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 exceeds 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.
