Reference: Rear Brake Components

CAUTION:
Take care not to damage piston and caliper cylinder of rear brake caliper.

DISASSEMBLY

Caliper cylinder
1) Clean around caliper cylinder.
2) Remove return spring (1).
3) Remove parking nut (2), washer (3), lever (4) and shaft cover (5).





4) Loosen piston (1) by turning in arrow direction using special tool.
Special Tool
(A): 09945-16060








5) Remove cylinder boot, piston seal and bleeder plug.

Slide pin
Remove slide pins (2) and pin boots (3) from caliper rear brake caliper carrier (1).





Reassembly

CAUTION:
^ Wash parts with specified brake fluid before assembling.
^ Do not use other brake fluid or volatile solvent.

Caliper
1) Perform the following procedures before installing brake piston to rear brake caliper.
a) Check entire periphery of brake piston and inside face of cylinder for rust, corrosion and any other damage. If any faulty is found, replace rear brake caliper.
b) Apply brake fluid to new piston seal (1) and install into groove in cylinder of rear brake caliper without twisting.

Brake fluid
Refer to reservoir cap of brake master cylinder or owners manual.





c) Apply brake fluid to new cylinder boot (1) and fit into cylinder boot groove of rear brake caliper as shown below.

Brake fluid
Refer to reservoir cap of brake master cylinder or owners manual.








2) Expand cylinder boot (1) and install piston (2) into caliper cylinder (3).





3) Turn piston (1) in arrow direction using special tool to screw piston into caliper cylinder.
4) Fit cylinder boot into boot groove of piston.

CAUTION:
Cylinder boot should not be twisted when installing piston.

NOTE:
Check that cylinder boot is securely fitted to entire boot groove of cylinder inner face of rear brake caliper and that of piston.

Special Tool
(A): 09945-16060





5) Apply grease to new shaft cover (1) inner surface and install to rear brake caliper.

NOTE:
Use rubber grease of which viscosity varies very little even at -40 degrees C (-40 degrees F).

6) Install lever (2) and washer (3) and tighten parking nut (4) to specified torque.

Tightening torque
Parking nut (a): 27 Nm (2.8 kg-m, 20.0 lbf-ft)

7) Install return spring (5) and engage it with lever.





8) Install bleeder plug to rear brake caliper and tighten to specified torque.

Tightening torque
Bleeder plug (a): 7.0 Nm (0.71 kg-m, 5.5 lbf-ft)

Slide pin
1) Check the following points before installing slide pin to rear brake caliper carrier.
a) Check slide pins for rust, corrosion and other damage and replace them if defective.
b) Apply grease to inner side of new pin boot (1).
c) Direct pin boots (1) as shown and install them to rear brake caliper carrier (2).

NOTE:
Use rubber grease of which viscosity varies very little even at -40 degrees C (-40 degrees F).





d) Apply grease to slide pin (1).

NOTE:
Use rubber grease of which viscosity varies very little even at -40 degrees C (-40 degrees F).





2) Install slide pin with three grooves (upper side) (1) and slide pin without groove (lower side) (2) to rear brake caliper carrier (3) as shown.
