Rear Brake Pads
Inspection and Replacement
Never use an air hose or dry b.ush to clean brake
assemblies.
Use an OSHA-approved vacuum cleaner to avoid
breathing brake dust.
Block the front wheels. loosen tha rear wheel nuts
slightly, support the rear of vehicle on sstety
stands, then remove the rear wheels.
Relaase the parking brake,
Remove the caliper shield.
Remove the two caliper mounting bolts and the
caliper trom the bracket.
CAUTION:
. Thoroughly clesn the out3ide ol tho csliper to
prsvent dust and dirt from entering in3ido,
. Support the caliper with a pi€c€ ot wire so that
it doss not hang lrom ths brako hose.

VINNER PAD SHIMCheck for weakness.(All exc.pt Type Rmod.ll
Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickn..s:
Standard:
Typo R Model:
8.5 - 9.5 mm (0.33 - 0.37 in)
All except Type R Model:
7.0 - 8.0 mm {0.27 - 0.31 in)
Sorvie Limit: 1.6 mm {0.06 inl

lf the pad thickness is less than the service limit,
replace the pads and shims together as a set.

Rear Brake Disc
Disc Runout Inspection
Loosen the rear wheel nuts slightly, then raise the
vehicle and support it on safety stands. Remove the
rear wneers.
Remove the brake pads (see page 19-16).
Inspect the disc surface for damage or cracks. Clean
the disc thoroughly and remove all rust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and measure the runout at 10
mm (0.4 in) in from the outer edge of the disc.
Brake Disc Runout:
Se.vice Limit: O.1O mm {0.0O4 in) max.
ll the disc is beyond the service limit, refinish the
brake disc.
Max. Refinishing Limit: 8.0 mm (0.32 in)
DIAL INDICATOR
NOTEi A new disc should be refinished if its runout
is greater than 0.'10 mm (O.O04 in).
Disc Thickness and Parallelism
Loosen the rear wheel lug nuts slightly, then raise
the vehicle and support it on safety stands. Remove
the rear wheels.
Remove the brake pads (see page 19-16).
Using a micrometer, measure disc thickness at
eight points, approximately 45" apart and 10 mm
(0.4 in) in from the outer edge of the disc. Replace
the brake disc if the smallest measurement is less
than the max. retinishing limit.
Bfake Disc Thickness:
Standard: 8.9 - 9.1 mm
(0.35-0.36 in)
Max. Refinishinq Limit:8.O mm (0.31 in)
NOTE: Replace the brake disc it the smaLlest mea-
surement is less than the max. retinishing limit.
Brake Disc Parallelism: O.O15 mm
(O.00O6 in) max.
NOTE: This is the maximum allowable difference be-
tween the thickness measurement.
lf the disc is bevond the service limit for parallelism,
refinish the brake disc.
NOTE: See section 18 for brake disc replacement.

Disassembly/Reassembly
o Never use an air hose or dry brush to clean brake assemblies.o Use an OSHA-approv€d vacuum cleaner to avoid breathing brake dust.. Conlaminated brake discs or pads reduce stopping ability.. When reusing the pads, always reinstall the brake pads in their original positions to prevent loss of braking efficiency,
CAUTION: Do not spill brake fluid on the vehicle; it may damags the paint; it brake fluid does contast the paint, wash itoff immediately with water,
NOTE:
. Coat the piston. piston seal, and caliper bore with clean brake fluid.. Beplace all rubber parts with new ones whenever disassembled.o Clean all parts in brake fluid and air dry; blow out all passages with compressed air.a Before reassembling, check that all parts are free of dust and other foreign particles.
. Replace parts with new ones whenever specified to do so.. Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.. Always use Genuine Honda DOT3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the lifeof the svstem.

Anti-lock Brake SYstem (ABS)
when the brake pedal is depressed during driving, the wheels can lock before the vehicle comes to a stop. In such an event.
the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is reduced if the
rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip rate o{ the wheels to
ensUre maximum grip force from the tires, and it thereby ensures maneuverbiIity and stabiIity of the vehicIe.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed. then it controls the brake
fluid oressure to attain the target slip rate
