Inspection 

Check the thickness of the inner and outer pads "A". See Fig. 49 . Do not include the thickness of the backing 
plate. See DISC BRAKE SPECIFICATIONS . If the brake pad thickness is less than the service limit, replace 
all the pads as a set.

Disc Runout Inspection 

1. Inspect the disc surface for damage and cracks. Clean disc thoroughly, and remove all rust. Install 

suitable flat washers "A" and wheel nuts, and tighten the nuts to the specified torque to hold the brake 
disc securely against the hub. See DISC BRAKE SPECIFICATIONS . See Fig. 50 .  

2. Set up the dial gauge against the brake disc and measure the runout at .4" (10 mm) from the outer edge of 

the disc. See DISC BRAKE SPECIFICATIONS . See Fig. 50 .  

3. If the disc runout is beyond the service limit, refinish the brake disc. 

NOTE:

If the brake disc is beyond the service limit for refinishing, replace it. A 
new disc should be refinished if its runout is greater than .004" (.10 mm).

Brake Disc Thickness & Parallelism Inspection 

1. Using a micrometer, measure disc thickness at 8 points, approximately 45 degrees apart and .4" (10 mm) 

in from the outer edge of the disc. See Fig. 37 . Replace the brake disc if the smallest measurement is less 
than the minimum thickness. See DISC BRAKE SPECIFICATIONS . 

2.  

If the disc is beyond the service limit for parallelism, refinish the brake disc. If the brake disc is beyond 
the service limit for refinishing, replace it. See DISC BRAKE SPECIFICATIONS .  

Installation 

NOTE:

Parallelism is the difference between the thickness measurements.

WARNING:

Contaminated brake discs and pads reduce stopping ability.

1. Clean and install the pad retainers. Apply Dow Corning Molykote M77 grease to both sides of shim "A", 

the back of the pads "B", and the other areas indicated by arrows. See Fig. 51 . Wipe excess grease off the 
shim and pads. 

2.  

Install the brake pads and pad shims correctly. Install the pads with the wear indicators "C" on the inside. 

3. Rotate the caliper piston "A" clockwise into the cylinder, then align the cutout "B" in the piston with the 

tab "C" on the inner pad by turning the piston back. See Fig. 52 . Lubricate the boot with rubber grease to 
avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly.  

4. Install the caliper. Install the flange bolts "D". Tighten flange bolts to specification while holding the pin, 

"E" with a wrench. See TORQUE SPECIFICATIONS . Be careful not to damage the pin boot. 

5.  

Press the brake pedal several times to ensure the brake works, then test drive. After installation, check for 
leaks at hose and line joints or connections, and retighten if necessary. 

WARNING:

If reusing the pads, always reinstall the brake pads in their original 
positions to prevent a momentary loss of braking efficiency.

NOTE:

Engagement of the brake may require a greater pedal stroke immediately 
after the brake pads have been replaced as a set. Several applications of 
the brake pedal will restore the normal pedal stroke.
