1. Rear Brake Caliper Exploded View

Exploded View



Disassembly


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.


NOTE:

Clean all parts in brake fluid and air dry; blow out all passages with compressed air.

Make sure no dirt or other foreign matter gets in the brake fluid.

Make sure no grease or oil gets on the brake discs or pads.

Do not reuse drained brake fluid. Use only new Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.

Refer to the Exploded View as needed during this procedure.


1. Rear Brake Caliper - Disassembly

Reassembly


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.


NOTE:

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 dirt and other foreign particles.

Make sure no dirt or other foreign matter gets in the brake fluid.

Make sure no grease or oil gets on the brake discs or pads.

Do not reuse drained brake fluid. Use only new Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.

Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.

Use recommended greases in the rear caliper set.

After installing the caliper, check the brake hose and line for leaks, interference, and twisting.

Refer to the Exploded View as needed during this procedure.


1. Rear Brake Caliper - Reassembly


NOTE: When disassembling the lever and the shaft, assemble them according to the following procedure, referring to the exploded view beforehand, then install them to the caliper.

Install the lever and a spring washer to the shaft.

Apply new sealant (Loctite 569) to the threads of the parking nut, and install it.

Clamp the lever in a vice, and tighten the nut.


1.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to the caliper pins (A) and the new pin boots (B).


2.

Install the pin boots.


3.

Install the caliper pins.


NOTE:

Make sure that the caliper pins are installed correctly. The upper caliper pin and the lower caliper pin are different. If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid brake pad wear, and possibly uneven tire wear.

Remove air with the inside of the boots.



4.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to a stop pin (A) of the caliper body.


NOTE: Check if notch of the stop pin faces to the cylinder.


5.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to the seal of a new shaft cover (B).


6.

Install the shaft cover.


7.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to the hole (C) in the shaft.


8.

Install the lever/shaft (D).


NOTE:

Rotate the shaft slowly when inserting so as not to damage the seal of the shaft cover.

Fix the lip of the shaft cover to the groove portion of the shaft completely.


9.

Install the return spring (E).



10.

Install the rod (A) to the shaft (B) so that it turns toward the center.


11.

Install the new O-ring (C) to the sleeve piston (D).


12.

Install the two pins (E) of the sleeve piston into the two holes (F) of the caliper body, so that the rod is inserted in the hole in the bottom of the sleeve piston.



13.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to the new cup (C), and assemble to the adjusting bolt (D).


NOTE: Install the cup with the groove facing toward bearing A.


14.

Assemble bearing A, the spacer (E), adjusting spring B, and the spring guide (F),


15.

Install them into the caliper body.



16.

Install the rear caliper spring compressor on the spring guide (A) in the caliper body.


17.

Turn the shaft (B) clockwise until the plate (C) touches the locknut (D).


18.

Check that the bottom (E) of the spring guide is lower than the circlip installation groove (F) in the caliper body.


19.

Install the circlip (A) with the snap ring pliers.


NOTE: Make sure the circlip securely fits in the groove of the caliper body.



20.

Apply a thin coat of Honda silicone grease (P/N 08C30-B0234M) to the new piston seal (A).


21.

Install the piston seal.


22.
