WARNING: Take care not to breath in brake dust. Brake dust is filled with asbestos which causes mesothelioma cancer and could result in development of a tumor. Mesothelioma destroys tissue and organs and have the potential to spread to other parts of the body. Always clean brake parts with a certified brake parts cleaner before working on the brake system. This will reduce the amount of exposure to asbestos.
All Honda Civic 1992-1995 models use front disc brakes. Rear brakes may be either disc type or self-adjusting drum type. Parking brake cable mechanism applies rear brakes.
BRAKE SYSTEM BLEEDING PROCEDURES
Raise and support vehicle. Fill master cylinder to maximum. Check fluid level after bleeding each wheel position. Bleed brakes in following sequence: RR, LF, LR and RF.
BRAKE PEDAL HEIGHT ADJUSTMENT
Loosen brakelight switch lock nut, and back off switch until it no longer touches brake pedal. Loosen brake pedal push rod lock nut, and screw push rod in or out until correct pedal height is obtained.
- Civic and Civic del Sol AUTOMATIC: 6.5 inches (165 mm)
- Civic and Civic del Sol MANUAL: 6.3 inches (160mm)
BRAKE WARNING LIGHT
Brake warning light indicates parking brake is engaged and/or brake fluid level is low. To adjust parking brake light operation, turn ignition on. Bend switch plate down until light comes on when parking brake lever is pulled one notch and goes out when lever is released.
MASTER CYLINDER PUSH ROD
Check and adjust master cylinder push rod-to-piston clearance before installing master cylinder.
- Install Push Rod Adjustment Gauge (07JAG-SD40100) so gauge rod makes light contact with secondary piston of master cylinder. Ensure gasket is in position when adjusting rod clearance.
- Remove push rod adjustment gauge from master cylinder, and install gauge onto brake booster. See figure. Tighten mounting nuts to specification. Using engine or outside vacuum source, apply at least 10 in. Hg vacuum to brake booster. Check clearance using feeler gauge
- Civic and Civic del Sol: 0-.016″ (0-.40 mm)
Before adjusting parking brake, loosen equalizer adjusting nut. Start engine, and depress brake pedal several times to set self-adjusting brakes before adjusting parking brake.
- With rear brakes adjusted, raise and support rear of vehicle. Loosen equalizer nut, and pull parking brake lever up one notch. Tighten equalizer adjusting nut until rear wheels drag slightly.
- Release parking brake lever. Rear wheels should rotate freely. Rear wheels should lock when parking brake lever is pulled up 6-10 clicks.
REAR DRUM BRAKE SHOES
Rear brake shoes will self-adjust through brake pedal action. No in-service adjustment is required.
- Stoplight switch is located under dash, above brake pedal. To adjust, loosen lock nuts and turn switch until plunger is fully depressed (threaded end touching pedal arm pad).
- Back off switch 1/4 turn, and tighten lock nuts. Clearance between threaded end of switch body and brake pedal switch contact pad should be about .012″ (.30 mm). Ensure brakelights go off when pedal is released.
POWER BRAKE BOOSTER FUNCTIONAL TEST
- Start engine. Turn ignition off. Depress brake pedal several times. Depress pedal firmly and hold pressure for 15 seconds. If pedal sinks, master cylinder, brake line or wheel cylinder is faulty.
- With pedal depressed, start engine. If pedal sinks slightly, vacuum unit is working properly. If pedal height does not vary, booster or check valve is faulty.
POWER BRAKE BOOSTER LEAK TEST
- With engine running, depress brake pedal. Turn ignition off. If pedal height does not change while depressed for 30 seconds, vacuum booster is okay. If pedal rises, vacuum booster is faulty.
- Stop engine, and depress brake pedal several times using normal pressure. Pedal height should be low when first depressed. On consecutive applications, pedal height should gradually rise. If pedal height does not vary, check power brake booster check valve.
POWER BRAKE BOOSTER CHECK VALVE TEST
Disconnect power brake unit vacuum hose at booster. Start engine, and allow it to idle. Ensure vacuum is available at booster end of hose. If vacuum is not available, vacuum source or check valve is faulty. Repair vacuum source or replace check valve, and retest.
