Rear Brake Inspection

Check the cylinder bore and piston for rust or scoring.
If necessary, replace the cylinder and piston.

Using a ruler, measure the pad lining thickness.

Standard thickness:

10.5 mm (0.413 in.)

Minimum thickness:

1.0 mm (0.039 in.)

Check the 2 plates as follows. If necessary, replace the plates.

1. Use brake cleaner to clean the pad of the pad support plate and cylinder mounting contact surface. Inspect for deformation, cracks, rust and foreign matter that is difficult to remove.
   

2. Use brake cleaner to clean the pad support plate contact surface of the cylinder mounting. After installing the pad support plate to the cylinder mounting, inspect for looseness and deformation.
   

3. After installing the pad, inspect if the pad falls off easily (due to the spring force of the pad support plate).
   

Using a micrometer, measure the disc thickness.

Standard thickness:

12.0 mm (0.472 in.)

Minimum thickness:

10.5 mm (0.413 in.)

Check the bearing backlash and axle hub deviation (RAV4_ACA30 RM00000227V003X_01_0005.html).

Tighten the disc with the 5 hub nuts.

Torque:

103 N*m{1050 kgf*cm, 76 ft.*lbf}

Using a dial indicator, measure the disc runout 10 mm (0.39 in.) from the outer edge of the disc.

Maximum disc runout:

0.15 mm (0.0059 in.)

Remove the 5 hub nuts and disc.
