Parking Brake Switch Test
1. Remove the rear console, and disconnect theconnector (A)from the switch (B).
Check for continuity between the switch terminal
and body ground:
. With the brake lever up, there should be
continuity.. With the brake lever down, there should be no
continuity.

Brake Fluid Level Switch Test
Check for continuity between the terminals (A) with thefloat in the down position and the up position.
. Remove the brake fluid completely from the reservoir.
With the float down, there should be continuity.. Fjllthe reservoir with brakefluidto MAX(upper) level(B). With the float up, there should be no continuity.

Rear Brake Pads Inspection and Replacement
Frequent inhalation of brake pad dust, regardless ofmaterial composition, could be hazardous to your
hea hh.. Avoid breathing dust particles.. Never use an air hose or brush to clean brake
assemblies, Use an OSHA-approved vacuum
cleaner.
Inspection
'1. Raise the rear of the vehicle, and support jt with
safety stands in the proper location (see page 1-8).Remove the rear wheels,
2. Check the thickness of the inner pad (A) andouterpad (B). Do not include the thickness of the brakepad backing plate.
Brake pad thickness:
Standard: 8.5 9.5 mm {0.33-0.37 in.}
Service limit: 1.6 mm (0.06 in.)
B -::--
lf the brake pad thickness is less than the servicelimit, replace allthe pads as a set.
3.

Replacement
1. Remove the bolt (A) and brake hose {B} from themounting bracket.
Remove the caliper bolts (C), and remove thecaliper (D) from the caliper bracket.
Remove the pad shims (A) and pads (B).3.

Rear Brake Disc Inspection
Runout
1. Raise the rear of the vehicle, and support it with
safety stands in the proper location (see page 1-8).Remove the rear wheels,
2. Remove the brake pads (see page 19-20).
3. Inspect the disc surface for damage and cracks.
Clean the disc thoroughly, and remove all rust,
4. lnstall suita ble f lat washers (A) and wheel nuts, andtighten the nuts to the specified torque to hold thebrake disc securely against the hub.
108 N.m (11.0 kgf.m,80lbf.ft)
Set up the dial gauge against the brake disc as
shown. and measure the runout at 10 mm (0.4 in.)
from the outer edge of the disc.
Brake Disc Runout;
Service Limit: 0.10 mm {0.004 in.)
lf the disc is beyond the service limit, refinish thebrake disc.
Max. Refinish Limit: 9.0 mm (0.35 in.)
NOTE:. lf the brake disc is beyondtheservice limitfor
refinishing, replace it (see page 18-26).. A new disc should be refinished if its runout isgreater than 0.10 mm (0.004 in.).
19-22
Thickness and Parallelism
1. Raise the rear of the vehicle, and support with
safety stands in the proper location (see page l-g).Remove the rear wheels.
2. Remove the brake pads {see page 19 20).
3, Using a micrometer, measure disc thickness ateight points, approximately 45'apart and 10 mm
{0.4 in.) from the outer edge of the disc.
Brake Disc Thickness:
Standard: 9.9-10.1 mm (0.389 0.397 in.l
Max. Retinishing Limit: 9.0 mm (0.35 in.)
Brake Disc Parallelism: 0.016 mm 10.0006 in.)
max.
4.lf the smallest measurement is less than the max.
refinishing limit, replace the brake disc (see page
18-26).
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.

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.

NOTE:. The parking brake cables must not be bent or
distorted. This will lead to stiff operation and
premature failure.. Refer to the Exploded View as needed during this
proceoure.
1. Release the parking brake lever fully.
2. Remove the rear console (see page 20-57).
Remove the parking brake cable clip (A) from the
brake cable (B).4.
6.
Disconnectthe parking brake cable from the lever
{c).
Remove the parking brake cable mounting
hardware, then remove the cable.
7. lnstallthe new cable in the reverse order of
removal. and note these items:
. Be careful not to bend or distort the cable.. Make sure the parking brake cable clip is fully
seated on the cable housing.. Do the parking brake cable adjuslment (see page
19-7 ).
