Rear Brake Caliper Disassembly and Reassembly
Precautions: Precautions for Brakes · General safety (00)
Disassembly
Caliper
1)Clean surfaces around caliper cylinder.
2)Remove piston (1) by turning in arrow direction using special tool.
| 2. | Cylinder boot |
3)Remove cylinder boot (1) and bleeder plug (2).
4)Remove piston seal (1) from caliper cylinder of rear brake caliper (3) using flat-bladed screwdriver (2) or the like.
NOTICE:
If the inside surface of the cylinder (bore wall) and outside surface of piston are damaged, brake fluid leakage may result.
Be extremely careful not to damage the inside surface of the cylinder and outside surface of piston when removing the piston seal.
Slide pin
Remove slide pins (2) and pin boots (3) from rear brake caliper carrier (1).
Reassembly
WARNING:
Failure to take proper precautions when assembling the brake caliper can result in brake system failure, which could lead to an accident.
•Clean each part before installation using the same brake fluid as that in the master cylinder reservoir. Never use any other brake fluid or volatile solvent.
•Before installing the piston seal and cylinder boot to the cylinder, apply rubber grease included in the piston seal set or brake fluid to them.
•Fit a new piston seal securely into the groove of the cylinder checking that it is not twisted.
•Before installing the piston seal and cylinder boot to the cylinder, apply rubber grease included in the piston seal set or brake fluid to them.
•Fit a new piston seal securely into the groove of the cylinder checking that it is not twisted.
NOTE:
Use rubber grease whose viscosity varies very little even at –40 °C (–40 °F).
Caliper
1)Perform the following steps before installing brake piston to rear brake caliper.
a)Check entire periphery of brake piston and inside surface of cylinder for rust, corrosion and any other damage. If check result is not OK, replace rear brake caliper.
b)Apply grease included in piston seal set of supply parts or specified brake fluid to new piston seal (1), and then fit the seal into groove in caliper cylinder taking care not to twist the seal.
c)Coat new cylinder boot (1) with grease included in piston seal set of supply parts or specified brake fluid, and then fit the boot into groove in caliper cylinder as shown below.

2)Expand cylinder boot (1) and install piston (2) into caliper cylinder.
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.
NOTE:
Check that cylinder boot is completely fitted both in groove in caliper and groove in piston.
Slide pin
1)Check the following points before installing slide pins to rear brake caliper carrier.
a)Check slide pins for rust, corrosion and other damage and replace them if defective.
b)Apply rubber grease included in pin boot set of supply parts to inside of new pin boot (1).
c)Install pin boot (1) to rear brake caliper carrier (2) with its end directed as shown below.
d)Apply rubber grease included in pin boot set of supply parts to slide pins (1).
2)Install slide pin with three grooves (1) into rear side and slide pin with bushing (2) into front side of rear brake caliper carrier (3) as shown.
