and pump out the brake fluid carefully.
1. Remove:
• Brake caliper piston “1”
• Brake caliper piston dust seal “2”
• Brake caliper piston seal “3”
a. Blow compressed air into the brake hose joint
opening “a” to force out the piston from the
brake caliper.
WARNING
b. Remove the brake caliper piston seal and
dust seal.
CHECKING THE REAR BRAKE CALIPER

Scratches/wear
→
Replace the brake caliper
assembly.
• Brake caliper body “3”
Cracks/damage
→
Replace the brake caliper
assembly.
• Brake fluid delivery passages
(brake caliper body)
Obstruction
→
Blow out with compressed air.

ASSEMBLING THE REAR BRAKE CALIPER
WARNING
Before installation, all internal brake com-
ponents should be cleaned and lubricated
with clean or new brake fluid.
Never use solvents on internal brake com-
ponents as they will cause the brake caliper
piston dust seal and piston seal to swell
and distort.
Whenever a brake caliper is disassembled,
replace the brake caliper piston dust seal
and piston seal.
INSTALLING THE REAR BRAKE CALIPER
1. Install:
• Brake caliper “1”
• Copper washers
• Brake hose “2”
• Union bolt “3”
WARNING
Proper brake hose routing is essential to in-
sure safe vehicle operation. Refer to “CABLE
ROUTING” on page 2-33.
CAUTION:
When installing the brake hose onto the
brake caliper, be sure to position the brake
pipe “a” into the slot “b” in the brake caliper.
2. Install:
• Brake pad spring
• Brake pads
• Brake pad retaining bolts
• Rear brake caliper
Refer to “REPLACING THE REAR BRAKE
PADS” on page 4-30.
3. Install:
• Rear wheel
Refer to “REAR WHEEL” on page 4-10.
4. Fill:
• Brake fluid reservoir
(with the specified amount of the recom-
mended brake fluid)
WARNING
Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
Refill with the same type of brake fluid that
is already in the system. Mixing brake fluids
may result in a harmful chemical reaction,
leading to poor brake performance.
When refilling, be careful that water does
not enter the brake fluid reservoir. Water
will significantly lower the boiling point of
the brake fluid and could cause vapor lock.
CAUTION:
Brake fluid may damage painted surfaces
and plastic parts.Therefore, always clean up
any spilt brake fluid immediately.
