Checking the technical condition

Checking brake discs

1. Check the wear and condition of the brake pads.

2. Inspect the brake disc for cracks and other damage.

3. Clean the surface from rust and dirt and measure the thickness of the disc at least in eight points at the same distance (5 mm) from the outer circumference.

Note:

Brake disc thickness:

2WD:

• Standard value: 26 mm.
• Maximum permissible value: 24.4 mm.

4WD:

• Standard value: 28 mm.
• Maximum permissible value: 26.4 mm.

Deviation: less than 0.005 mm.

4. If the wear exceeds the limit, replace the discs and pads as a set on the left and right sides of the vehicle.

Checking brake pads

1. Check the brake pads for wear. Measure the pad thickness and replace it if the thickness is less than the specified value.

Note:

Brake pad thickness:

• Standard value: 11mm.
• Maximum permissible value: 2.0 mm.

2. Check for grease at the sliding contact points and check the brake pad, including its back side, for damage.

Checking the runout of brake discs

1. Place a dial indicator approximately 5 mm from the outer edge of the brake disc and measure the disc runout.

Note: Brake disc runout: Limit value: 0.025 mm or less (for new disc).

2. If the brake disc runout exceeds the specified limits, reinstall the disc and repeat the measurement.

3. If the runout does not exceed the specified limits, rotate the disc 180° and repeat the measurement.

4. If it is not possible to correct the runout by changing the position of the brake disc, replace the disc.

Installation

1. Installation is carried out in reverse order.

2. Use a special tool to install the caliper assembly (09581-11000).



3. After installation, bleed the brake system.
