Installation 

1. Install the rear jounce brake hose. See Fig. 23 . Install the brake hose lower bracket and bolt to the axle. 

Tighten the bolt to specification. See TORQUE SPECIFICATIONS . Remove the caps or plugs from 
the rear jounce hoses and connect the pipes to the junction block on the axle. Tighten the fitting to 
specification.

with any suspension component.

With the weight of the vehicle on the suspension, install the brake hose bracket bolt. Remove the rubber 
cap or plug from the exposed brake pipe fitting end. Connect the brake pipe fittings to the brake hoses. 
See Fig. 22 . Use a backup wrench on the hose fitting. DO NOT bend the bracket or the pipe. Tighten the 
brake pipe fitting to specification.  

3. Ensure that the hose does not make contact with any part of the suspension. If the hose makes contact, 

remove the hose and correct the condition. Bleed the hydraulic brake system. See BLEEDING BRAKE 
SYSTEM . Lower the vehicle.

Removal (Front & Rear) 

1. Inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between 

the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the 
reservoir before proceeding.  

2. If the brake fluid level is higher than midway between the maximum-full point and the minimum 

allowable level, remove brake fluid to the midway point before proceeding. Raise and support the vehicle. 
Remove the tire and wheel assembly. Inspect the caliper operation.  

3. For rear calipers, place a C-clamp as shown. See Fig. 24 . Slowly bottom the pistons of the caliper. It may 

be necessary to reposition the C-clamp to allow both of the pistons to bottom into the caliper bores.  

4. On all calipers, remove the caliper from the mounting bracket and support the caliper with heavy 

mechanic's wire or equivalent. See Fig. 25 . DO NOT disconnect the hydraulic brake flexible hose from 
the caliper.  

5. Remove the brake pads from the caliper mounting bracket. Remove and discard the anti-rattle clips from 

the brake caliper mounting bracket. See Fig. 26 . Inspect the caliper and mounting bracket. 

CAUTION: Avoid taking the following actions when you service wheel brake parts: 

DO NOT grind brake linings. DO NOT sand brake linings. DO NOT clean 
wheel brake parts with a dry brush or with compressed air. Some models 
or aftermarket brake parts may contain asbestos fibers which can become 
airborne in dust. Breathing dust with asbestos fibers may cause serious 
bodily harm. Use a water-dampened cloth in order to remove any dust on 
brake parts. Equipment is available commercially in order to perform this 
washing function. These wet methods prevent fibers from becoming 
airborne.
