11. Pivot the caliper down into position. Being carefulnot to damage the pin boots, install the bolt (B), and
tighten it to the specified torque.
12. Press the brake pedal several timestomakesure

NOTE: Engagement of the brake may require agreater pedal stroke immediately after the brakepads have been replaced as a set. Several
applications of lhe brake pedal will restore thenormal pedal stroke.
13. After installation, check for leaks at hose and linejoants or connections, and retighten if necessary.

SpecialTools Required
Pushrod adjustment gauge 07JAG-SD40100
NOTE: Brake booster pushrod-to-piston clearance mustbe checked and adjustments made, if necessarV, beforeinstalling the master cylinder.
1. Setthespecial tool (A) onthe mastercylinder bodv(B), push in the center shaft (C) until the top of itcontacts the end of the secondary piston {D) byturning the adjusting nut (E).
Without disturbing the center shaft's position,
installthe specialtool (A) backwards on the booster.
Install the master cylinder nuts (B), and tighten
them to the specified torque.
Connecl the booster in line with a vacuum gauge
{C) 0-101 kPa {0'-760 mmHg, 30 in.Hg) to thebooster's engine vacuum supply, and maintain anengine speed that will deliver 66 kPa (500 mmHg,20 in.Hg) vacuum.

5. With a feeler gauge (A), measure the clearance
between the gauge body and the adjusting nut (B)
as snown,
lf the clearance between the gauge body and the
adjusting nut is 0.4 mm (0.02 in.), the pushrod-to-
piston clearance is 0 mm. However. if the clearance
between the gauge body and the adjusting nut is
0 mm, the pushrod-to-piston clearance is 0 4 mm
{0.02 in.) or more. Therefore it must be adjusted
and rechecked.
Clearance: 0-0./t mm (0-0.02 in.)
lf the clearance is incorrect, loosen the star locknut
(A). and turn the adjuster (B) in or out to adjust.
. Adjust the clearance while the specified vacuum
is appiied to the booster.. Hold the clevis (C) while adjusting.

lf you are reusing the pads, always reinstall the
brake pads in their original positions to prevent a
momentary loss of braking efficiency.
11. Rotate the caliper piston clockwise into the cylinder,
then align the cutout (A) in the piston with the tab
{B) on the inner pad by turning the piston back so
the caliper can be installed on the pad. Lubricate
the boot with rubber grease to avoid twisting the
Diston boot. lf the piston boot is twisted, back it out
so it is positioned properly.

Rear Brake Caliper Overhaul
Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
' Avoid breathing dust particles.
. Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner'
Remove, disassemble, inspect, reassemble, and installthe caliper, and note these items:
. Donotspill brake fluid on the vehicle; it may damage the paint; if brake f luid gets on the paint, wash it off
immediately with water.. To prevent dripping. cover disconnected hose joints with rags or shop towels.
. Cleanall partsinbrakefluidandairdry;blowoutall passageswith compressed air'
. Before reassembling, check that all parts are free of dust and other foreign particles
. Replace pans with new ones as specified in the illustration.. Make sure no dirt or other foreign matter contaminates the brake fluid.
. When reusing pads, always reinstallthem in their original positions to prevent loss of b ra king efficie ncy.
. Do not reuse drained brake fluid.
. Use only clean Honda DOT 3 brake fluid. Non-Honda brake fluid can cause corrosion and shorten the life of the
system.. Do not mix different brands ot brake fluid as they may not be compatible.
. Coatthe piston, piston seal groove, and caliper bore with clean brake fluid.
. Make sure no grease or oil gets on the brake discs or pads.
. Replaceall rubber parts with new ones whenever disassembled.
. After installing the caliper, check the brake hose and line for leaks, interference. and twisting.
