WARNING
Clean brake system components using denatured alco-
hol. Do not use mineral-base cleaning solvents, such as
gasoline or paint thinner. Use of mineral-base solvents
causes deterioration of rubber parts that continues after
assembly. This may result in improper brake operation
which could result in death or serious injury.
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 pas-
sages.
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. See

WARNING
Always replace brake pads in complete sets for correct
brake operation. Never replace just one brake pad. Fail-
ure to install brake pads as a set could result in death or
serious injury.
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
Place clip (1) inside caliper body as
shown.
NOTE
To ensure 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
Always make sure brake pad retainer is in
place on caliper mount before installing pads and caliper.
3.
Install brake pads (3) using pad hanger
and pin plug (2).
a. Install pad hanger pin (metric). Tighten to 11-14 ft-
lbs (15-19 Nm).
b.
Install pin plug. Tighten to 22-26 in-lbs (2-3 Nm).
4.
Install a new bleeder valve (metric) if necessary and
tighten to 36-60 in-lbs (4-7 Nm).
