Rear Brakes

Torque/Inspection

• Never use an air hose or dry brush to clean brake

assemblies.

• Use an OSHA-approved vacuum cleaner to avoid

breathing brake dust.

• Contaminated brake discs or pads reduce stopping

ability.
CAUTION:

• Do not spill brake fluid on the vehicle; it may damage

the paint; if brake fluid does contact the paint, wash

it off immediately with water.

• To prevent spills, cover the hose joints with rags or

shop towels.

• Clean all parts in brake fluid and air dry; blow out all

passages with compressed air.

• 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 DOT 3 Brake Fluid. Using

a non-Honda brake fluid can cause corrosion and

decrease the life of the system.

NOTE:

• Coat piston, piston seal, and caliper bore with clean

brake fluid.

• Replace all rubber parts with new ones whenever dis-

assembled.ProCarManuals.com

Inspection/Replacement (cont'd)
Rear Brake Pads

11. Install and tighten the two caliper mounting bolts.

12. Insert the cable through the arm, and connect the

cable to the lever with the clevis pin and new lock

pin. Install the new cable clip securely.

13. Install the caliper shield.

14. Depress the brake pedal several times to make sure

the brakes work, then test-drive the vehicle.

NOTE: Engagement of the brake may require a

greater pedal stroke immediately after the brake

pads have been replaced as a set. Several applica-

tions of the brake pedal will restore the normal

pedal stroke.

15. Install the rear wheels and torque the wheel nuts.

NOTE: Clean the mating surfaces of the wheel and

hub before installing the wheel.ProCarManuals.com

Ignition System

Spark Plug Inspection

1. Inspect the electrodes and ceramic insulator for:

Worn or deformed

electrodes

Cracked

insulator

Burned or worn electrodes may be caused by:

Advanced ignition timing

Loose spark plug

Plug heat range too hot

Insufficient cooling

Fouled plug may be caused by:

Retarded ignition timing

Oil in combustion chamber

Incorrect spark plug gap

Plug heat range too cold

Excessive idling/low speed running

Clogged air cleaner element

Deteriorated ignition coil
2. Replace the plug if it is fouled or worn. Do not use

spark plugs other than those listed below.

Spark Plug:

PFR6L-11 (NGK)

PK20PR-L11 (DENSO)

3. Make sure that the 1.3 mm (0.051 in) plug gauge

does not go into the gap for the platinum tip plug. If

the gauge goes into the gap, do not attempt to

adjust the side electrode; replace the plug with a

new
one.

Electrode Gap:

Platinum tip plug:

Check and confirm that the

1.3 mm (0.051 in) plug

gauge does not go into the

gap.

Anti-seize compound

applied to threads

4. Apply a small quantity of anti-seize compound to

the plug threads before installing each plug. Screw

the plugs into the cylinder head finger-tight, then

torque them to 18 N-m (1.8 kgf-m, 13 Ibf-ft).
Improper gap

Oil-fouling

Carbon deposits

Cracked center

electrode insulator
Damaged
