cleaning and lubricating.
• Never use solvents on internal brake com-
ponents as they will cause the piston seals
to swell and distort.
• When the brake caliper is disassembled, re-
place the brake caliper piston seal and the
brake caliper piston dust seal with new
ones.

INSTALLING THE FRONT BRAKE CALIPER
1. Install:
•
Front brake caliper bracket
•
Front brake caliper
(temporarily)
•
Copper washer
•
Brake hose
•
Union bolt
WARNING
EWA13531
Proper brake hose routing is essential to in-
sure safe vehicle operation.
NOTICE
ECA24460
Make sure that the pipe portion “a” of the
brake hose touches the projection “b” on the
brake caliper.
2. Install:
•
Front brake caliper
•
Brake pad spring
•
Brake pad
•
Brake pad pin
•
Plate
Refer to “CHECKING THE FRONT BRAKE
PADS” on page 3-24.
3. Tighten:
•
Plate bolt “1”
TIP
Make sure that the plate “2” is installed with its
upper end “a” aligned with the paint “b” on the
brake hose.
4. Pour brake fluid to the brake master cylinder
reservoir up to the specified level.
WARNING
EWA13090
• 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.
NOTICE
ECA13540
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean up
any spilt brake fluid immediately.
