CLEANING AND INSPECTION
Use denatured alcohol to clean brake system components.
Do not use mineral-based solvents (such as gasoline or
paint thinner), which will deteriorate rubber parts even
after assembly. Deterioration of these components can
cause brake failure, which could result in death or serious
injury. (00291a)
1. Clean all parts with denatured alcohol or D.O.T. 4 BRAKE
FLUID. Do not contaminate with mineral oil or other
solvents. Wipe dry with a clean, lint free cloth. Blow out
drilled passages and bore with a clean air supply. Do not
use a wire or similar instrument to clean drilled passages.
2. Carefully inspect all components. Replace any parts that
appear damaged or worn. Do not hone caliper piston bore.
3. Inspect brake rotor.
a. Measure rotor thickness. Replace if minimum thick-
ness is less than 0.18 in. (4.5 mm).
b. Check rotor surface. Replace if warped or badly
scored. Refer to
Table 2-24 .
Always replace brake pads in complete sets for correct
and safe brake operation. Improper brake operation could
result in death or serious injury. (00111a)
4. Inspect brake pads for damage or excessive wear.
Replace both pads as a set if the friction material of either
pad is worn to 0.04 in. (1.0 mm) or less.

ASSEMBLY
1. See Figure 2-82 . Place clip (1) inside caliper body as
shown.
NOTE
To verify proper brake pad-to-brake rotor clearance when the
caliper is installed, piston must be pressed all the way into the
bore whenever new brake pads are used.
2. Install pistons and o-rings.
a. Apply a light coat of D.O.T. 4 BRAKE FLUID to o-
rings, piston and caliper piston bore.
b. Place two new o-rings inside grooves of piston bore.
c. Install piston inside caliper body.
NOTE
See Figure 2-84 . Always make sure brake pad retainer is in
place on caliper mount before installing pads and caliper.
3. See Figure 2-82 . Install brake pads (3) using pin plug and
pad hanger (2).
a. Install pad hanger pin (metric). Tighten to 11-14 ft-lbs
(15-19 Nm).
b. Install pin plug. Tighten to 24 in-lbs (2.7 Nm).
4. Install a new bleeder valve (metric) if necessary and
tighten to 36-60 in-lbs (4-7 Nm).
