Component Tests and General Diagnostics

Front Disc Brake Mounting and Hardware Inspection

1. Use a siphon in order to remove half of the brake fluid from the reservoir.




2. Install a large C-clamp over the brake caliper (10). Position the ends of the C-clamp against the rear of the caliper body and against the outer brake pad.
3. Tighten the C-clamp in order to compress the caliper piston into the caliper bore.
4. Remove the C-clamp from the caliper.
5. Attempt to move the caliper up and down. Verify the caliper is not loose.
6. Attempt to move the caliper in and out. Verify the caliper slides smoothly with minimal force.
7. Inspect the caliper bolts (11,18) for the following conditions:
^ Corrosion
^ Damage
^ Looseness
^ Seizing
8. If any of the conditions exist, replace the caliper mounting hardware.
9. Inspect the caliper bracket (14) for damage.
10. If the bracket is damaged, replace the bracket.
11. Gently pull the caliper slide pins (17,21) outward without disengaging the slide pins from the boots (15,20).
12. Gently push the slide pins inward.
13. Inspect for the following:
^ Caliper bolt damage
^ Caliper bracket damage
^ Looseness in the caliper mounting bracket
^ Missing components
^ Cracked or torn slide pin boots
^ Binding
^ Seizing
^ Corrosion
14. If any of the conditions exist, replace the caliper mounting hardware.




15. Inspect the disc brake pad hardware (1,2,3,4,5,7,8,9) for the following:
^ Bent components
^ Excessive corrosion
^ Looseness at the disc brake pads
^ Missing hardware
16. If any of the conditions exist, replace the disc brake hardware.
17. Verify the pads slide easily and without binding on the hardware.
