Honda Civic Service Manual: Front Brake Disc Inspection (Except Natural Gas models)


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.


1. Vehicle Lift

1.

Raise the vehicle on a lift, and make sure it is securely supported.


2. Front Wheel

1.

Remove both front wheels.


3. Front Brake Pad


1.

Remove the flange bolt (A).


2.

Pivot the caliper body (B) up out of the way.


NOTE:

Be careful when pivoting the caliper body up or the spring could pop out of position.

Check the hose and pin boots for damage and deterioration.


3.

Remove the pad return springs (A).


-1:caliper-2in

4.

Remove the pad shims (A) and the brake pads (B).


1. Front Brake Disc Thickness and Parallelism - Inspection


1.

Using a micrometer (A), measure the brake disc thickness at eight points, about 45 ° apart and 10 mm (0.39 in) in from the outer edge of the brake disc.


Replace the brake disc if the smallest measurement is less than the maximum refinishing limit.


Brake disc thickness:

 

Standard:

   

14 inch brake caliper:

21.0 mm (0.827 in)

   

15 inch brake caliper:

23.0 mm (0.906 in)

   

16 inch brake caliper:

25.0 mm (0.984 in)

 

Maximum refinishing limit:

   

14 inch brake caliper:

19.0 mm (0.748 in)

   

15 inch brake caliper:

21.0 mm (0.827 in)

   

16 inch brake caliper:

23.0 mm (0.906 in)

Brake disc parallelism*:

0.015 mm (0.00059 in) max.


*: This is the maximum allowable difference between the thickness measurements.


2.

If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a Honda-approved commercially available on-car brake lathe.


NOTE: If the brake disc is beyond the service limit for refinishing, replace it.


3.

Inspect the brake disc runout.


2. Front Brake Disc Runout - Inspection


1.

Inspect the brake disc to wheel surface for damage and cracks.


2.

Clean the brake disc thoroughly, and remove all rust.


3.

Install suitable flat washers (A) and the wheel nuts (B).


4.

Tighten the wheel nuts to the specified torque to hold the brake disc securely against the hub.


5.

Set up the dial gauge (C) as shown.


6.

Measure the runout at 10 mm (0.39 in) from the outer edge of the brake disc.


Brake disc runout:

 

Service limit:

0.04 mm (0.0016 in)


7.

If the brake disc is beyond the service limit, refinish the brake disc with a Honda-approved commercially available on-car brake lathe.


Maximum refinishing limit:

 

14 inch brake caliper:

19.0 mm (0.748 in)

 

15 inch brake caliper:

21.0 mm (0.827 in)

 

16 inch brake caliper:

23.0 mm (0.906 in)


NOTE:

If the brake disc is beyond the service limit for refinishing, replace it.

If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is out of specification, refinish the disc.



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.


1. Front Brake Pad


1.

Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of the shims (A), the back of the brake pads (B), and the other areas indicated by the arrows.


NOTE: Wipe off the excess assembly paste from the pad shims and brake pads friction material.


2.

Install the brake pads and the pad shims.


NOTE: Install the brake pad with the wear indicator (C) on the upper inside position.


3.

Install the pad return springs (A).



4.

Pivot the caliper body (A) down into position.


5.

Install the flange bolt (B).


6.

Press the brake pedal several times to make sure the brakes work.


NOTE: Engagement may require a greater pedal stroke immediately after the brake pads have been replaced as a set. Several applications of the brake pedal will restore the normal pedal stroke.


2. Front Wheel

mmmln-mnomm

1.

Install both front wheels.


NOTE: Before installing the wheel, clean the mating surfaces between the brake disc and the inside of the wheel.
