Air HONDA CIVIC 1998 6.G Workshop Manual

Front Brake Caliper
Reassembly (cont'd)
2056 Type:
. Never use an air hose or dry b.ush to clean brake assemblies.. Uso an OSHA approved vacuum cleansr to avoid breathing brake dust.. Contaminated brake discs or pads reduce stopping ability.t when reusing the pads, always r6instsll the brake pads in their original positioos to prevent loss ol braking efficiency.
CAUTION:
' Do not spill brake tluid or th€ vehicle; it m8y damage the paint; if brake fluid does contact the paint, wash it off imme-diately with water.
. Clean all parts in brake tluid and air dry; blow out all passages with compr63ed air.. Beforo reassembling, check that all parts are fr€e of dust and other foreign particles,. Replace parts with new ones whenevea specified to do so.. Make sure no dirt or other foreign matter is allowad to contaminato the brake fluid,' Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can caus€ corrosior and decrease thelife ol the system.
NOTE:
. Coat the piston, piston seal, and caliper bore with clean brake fluid.. Replaceall rubber parts with new ones whenever disassembled.

Inspection and Replacement
Never use an air hose or dry brush to clean brakeassemblies.
Use an OsHA-apptoved vacuum cl€aner to avoidbreathing brake dust,
Block the front wheels, loosen the rear wneet nutsslightly, support the rear of the vehicle on safetystands, then remove the rear wheels.
Release the parking brake, and remove the calioersh ield.
CALIPER SHIELD
Remove the brake hose clamp bolt from the trailingarm first, then remove the two caliper mountingbolts and the caliper from the bracket.
CAUTION:
. Thoroughly clean the outside of the caliDer toprevent dust and dirt trom entering inside.. Support the calipor with a pieco of wire so thatit does not hang fuom the brake hose.
NOTEr Check the hoses and pin boots for damageor deterioration.

Using vernier calipers, measure the thickness ofeach brake pad lining. The measurement does notanclude the pad backing plate thickness.
Brake Pad Thickness:
Standard: 7.0 - 8.0 mm {0.28 - 0.31 in}Service Limit: 1.5 mm {0.06 in}
lf the pad thickness is less than the service limit,replace the pads and shims together as a set.

Kickback
1. The motor operates when the ABS is functioning, and the fluid in the reservoir is forced out to the master cylinder
causing kickback at the brake pedal.
2. TheABScontrol unit operates the solenoid valve when the brake pedal is released afterthe initial diagnosis Youmay
hear the faint solenoid valve operation sound at this time. but it is normal.
Pump Motor
1. The pump motor operates when the ABS is functioning
2. The ABS control unit checks the pump motor operation during acceleration. You may hear the faint operation sound
at this time. but it is normal.
Brake Fluid Replacament/Air Blsading
1. Brake fluid replacement and air bleeding procedures are the same as for conventional brakes
Troubleshooting
1. The troubleshooting flowcharts explain the procedures on the assumption that the cause of the problem is still pre-
sent and the ABS indicator light is still on.
Note that troubleshooting following the flowchart when the ABS indicator light does not come on can result in incor-
rect judgment.
2. Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
self,diagnosis is made at various times such as the initial diagnosis, except ABS control. during ABS control, during
acceleraiion, during the specified vehicle speed, etc. Therefore, the symptom cannot be checked unless the check
conditions match with the problem conditions
3. When the ABS indicator light does not come on during the test drive, but the troubleshooting is performed based on
the DTC, check for the loose connectors. poor contact of the terminals, etc, before troubleshooting.
4. After troubleshooting, erase the DTC and test-drive the car. Be sure that the ABS indicator light does not come on.
5. The connector illustrations show the female connectors with a single outline and the male connectors with a double
ouflrne.
6. The connector terminal cavities containing female terminals are always numbered by looking at the connector from
the wire side. and the cavities containing male terminals are always numbered by looking at the connector from the
terminal side.
