1. Check the brake fluid level in the expansion tank of the master brake cylinder.
- If the brake fluid level is halfway between the lower and upper marks, no additional operations with the brake fluid are required.
- If the brake fluid level is above the midpoint between the lower and upper marks, it is necessary to remove some of the brake fluid using a syringe before starting work.
2. Raise and secure the vehicle.
3. Remove the front wheel from the vehicle.
4. Compress the brake caliper body and try to move it up and down and back and forth relative to the caliper bracket. If excessive play is detected, the brake caliper bracket bushings and/or brake caliper bolts must be replaced.
5. Compress the front brake caliper pistons:
- Install a large C-clamp through the top of the caliper body against the back of the outer pad.
- Slowly tighten the C-clamp to fully compress the pistons into the caliper bores.
- Remove the C-clamp from the caliper.
6. With the pistons pressed into the caliper bores, compress the brake caliper body and move it back and forth on the brake caliper mounting bolts. Check for smooth movement. If a lot of force is required to move the caliper body or the caliper body does not move smoothly, check the brake caliper mounting bolts and/or caliper bracket bushings for wear or damage. If defects are found, replace the brake caliper mounting bolts and/or caliper bracket bushing.
7. Remove the brake caliper mounting bolts from the caliper bracket and secure the caliper with strong wire. Do not disconnect the brake hoses from the caliper.
8. Remove the brake pads from the brake caliper bracket.
9. Check the brake shoe mounting hardware for the following:
- Loss of fastening elements.
- Excessive corrosion.
- Deformation of mounting keys.
- Looseness in the brake caliper bracket.
- Weakness in the brake pads.
- Excessive contamination of the mounting surfaces on the caliper bracket and threads.
10. If any of the listed defects are detected, the brake pad mounting equipment must be replaced.
11. Make sure the brake pads are securely locked into place on the caliper bracket but move easily over the mounting elements without binding.
12. Check the caliper bolts (1) for the following:
- Jamming.
- Grasping.
- Looseness in the caliper bracket (3).
- Deformation or damage to the brake caliper mounting bolts.
- Cracking or lifting of anthers (4).
- Absence of anthers.
- Deformation or damage to the caliper bracket (3).
13. If any of the listed defects are detected, the brake pad fastening elements must be replaced.
14. Install the brake pads onto the caliper bracket.
15. Install the brake caliper onto the mounting bracket.
