Examination
Check pad thickness. If the pad thickness is less than the limit, replace the inner and outer pads as a set.
- Standard shoe thickness: 11mm
- Maximum pad thickness: 1.6 mm
Without taking into account the thickness of the metal plate.
Replacement
Attention. Make sure that oil does not get on the friction surfaces of the pads and the brake disc.
The procedure for replacing brake pads is considered using the example of 2WD models.
1. Disconnect the brake hose from the steering knuckle.
2. While holding the caliper pin with a hex wrench, unscrew the lower flange bolt (10 mm) and turn the caliper body up.
3. Tie the caliper body with wire.
Attention. Do not hang the caliper body on the brake hose. Do not damage the brake hose with the bracket and other components.
4. Remove the brake pads and shims from the caliper bracket.
5. Remove the shoe holders and clean them.
6. Clean the caliper bracket.
7. Install shoe holders.
8. Apply Morikoto M77 or Daikarubu 528D grease to the areas indicated by the arrows in the figure.
Attention:
- Apply the lubricant so that the lubricant does not squeeze out during the installation of the gaskets.
- Do not apply grease to the friction surfaces of the brake disc and brake pads.
9. Clean the caliper body and carefully push in the piston.
Make sure there is no brake fluid leaking from the reservoir on the master cylinder.
10. Return the caliper body to its original place and, holding the caliper pin with a hex wrench, tighten the flange bolt.
11. Connect a brake hose to a rotary fist.
12. Extend the piston by depressing the brake pedal several times.
Attention. Do not start with the pistons not extended. If the piston is pushed in too far, braking performance may not be sufficient when the pedal is pressed for the first time.
13. Check the brake fluid level in the reservoir.
14. After assembly, check if the brake hose is kinked, if the brake hose is in contact with other components, and if there is any leakage of brake fluid.
