Removal

1. CAUTION: Install a new lining if worn to or past the specified thickness above the metal backing plate or rivets. Install new pads in complete axle sets.

If necessary, using a suitable suction device, remove the brake fluid in the master cylinder reservoir until it is half filled.
2. Remove the wheel and tire assembly.





3. Inspect the brake pads for wear or contamination.





4. CAUTION: If the anchor housing spring is to be reused, do not force the anchor housing spring off the brake caliper. Do not install a damaged anchor housing spring.

Remove the anchor housing spring.





5. NOTE: Verify if the anchor housing spring has 1 end with 2 tabs. If yes, the LH side anchor housing spring must be installed with the 2-tabbed end in the upper brake caliper cavity.

For the LH brake caliper, release the lower portion of the anchor housing spring.
^ Apply force at the center of the anchor housing spring and pull outward at the bottom of the anchor housing spring to remove it from the lower brake caliper cavity.





6. Rotate the spring upward then remove it from the brake caliper.





7. NOTE: On the RH side, the anchor housing spring must be installed with the 2-tabbed end in the lower brake caliper cavity. The illustration below shows the anchor housing spring end with 2 tabs.

For RH brake caliper, release the upper portion of the anchor housing spring.
^ Apply force at the center of the anchor housing spring and pull outward at the top of the anchor housing spring to remove it from the upper brake caliper cavity.





8. Rotate the spring downward then remove it from the brake caliper.





9. NOTE: Do not allow the brake caliper to hang from the brake hose.

Remove the brake caliper.
1 Remove the zero-drag spring.
2 Remove and discard the brake caliper-to-anchor plate bolts, guide pins and boots.
10. Remove the brake pads from the brake caliper.

11. NOTE: Use a wood block or used brake pad to protect the brake caliper piston boots.

Compress the brake caliper pistons.





12. Measure the brake disc thickness.
^ Install a new brake disc if it is not within specification.

Installation
1. Using brake parts cleaner, clean the inner surfaces of the brake caliper where the brake pads attach.
2. Install new brake hardware as follows:
^ Install the guide pin bushings into the caliper bores.
^ Apply grease to the inside of the guide pin bushing. Do not apply grease to the guide pin threads.
^ Push the guide pins into the bushing.
3. Install the inboard brake pad into the brake caliper.
4. Remove the protective paper from the outboard brake pad and install it into the brake caliper.
5. Install the brake caliper on the brake disc.
6. Tighten the guide pins and install the dust caps.
7. Install the zero-drag spring.

NOTE: If present, the 2-tabbed end of the anchor housing spring must be installed first.





8. Install the anchor housing spring.
1 Insert tab of the anchor housing spring into the brake caliper cavity.
2 Twist tab into the brake caliper cavity (LH side-upper brake caliper cavity/RH side-lower brake caliper cavity).





9. Rotate the anchor housing spring and position the upper portion onto the anchor plate.





10. Position the other anchor housing spring portion onto the brake caliper anchor plate.
11. Push down and inward until the upper and lower ends of the anchor housing spring are latched and seated in the brake caliper cavities.





12. NOTE: The latch MUST be positioned as shown.

Verify that the anchor housing spring is correctly latched.
13. Install the wheel and tire assembly.
14. Apply the brake several times to verify correct brake operation.
