Assembly and Installation

Linings

CAUTION

Replace the linings on both brakes of a single

axle at the same time. Use Meritor parts. The use

of non-Meritor parts can damage the discs and

affect brake operation.

1. Place blocks under the wheels of the vehicle to

keep the vehicle from moving.

2. Install the linings in the caliper housing with

the metal backing plate against the pistons and

not toward disc.

WARNING

Take care when you use Loctite

to avoid serious

personal injury. Follow the manufacturer’s

instructions to prevent irritation to the eyes

and skin.

3. Apply Loctite

271 or equivalent to the threads

of the bolts and fasten the end plates to the

housing.

4. Install the end plates onto the housing. Install

the bolts and tighten them to 165-210 lb-ft

(224-285 N•m). Ensure that the linings move

freely in the housing.

5. Remove the air from the brake system. Refer to

“Remove Air From the System,” below.

6. Apply and release the brakes three times to

ensure the caliper operates correctly. Check for

fluid leaks. Ensure that the linings move freely

in the housing.

6. Check that the housing is installed correctly on

the mounting bracket. The disc must be within

+ 0.06 inches (+

1.5 mm) of being centered

between the lining end plates.

NOTE: Shims must be steel, and ground flat and

parallel.

•

If it is necessary to install a shim: Install the

shim either between the housing and mounting

bracket, or between the hub and disc, to

increase outboard clearance and decrease

inboard clearance.

A shim must cover the entire hub or housing

mounting surface, and the linings must move

freely in the housing and between the end

plates.

7. Remove the plugs from the brake line and the

inlet fitting. Connect the brake line to the inlet

fitting.

8. Remove the air from the brake system. Refer to

“Remove Air from the System.”

fluid leaks. Check that the linings move freely in

the caliper.
