Front Brake Caliper Removal and Installation

B940H24206004

NOTE
The right and left calipers are installed
symmetrically and therefore the removal
procedure for one side is the same as that for
the other side.

Removal

1) Drain brake fluid. Refer to “Brake Fluid Replacement

in Section 4A (Page 4A-6)”.

2) Remove the brake hose from the caliper by

removing the union bolt (1) and catch the brake fluid
in a suitable receptacle.

NOTE
Place a rag underneath the union bolt on the
brake caliper to catch any spilt brake fluid.

3) Remove the caliper by removing the caliper

mounting bolts (2).

Installation

Install the brake caliper in the reverse order of removal.
Pay attention to the following points:
• Tighten each bolt to the specified torque.

Tightening torque
Front brake caliper mounting bolt (a): 39 N·m (3.9
kgf-m, 28.0 lbf-ft)

• After setting the brake hose union to the stopper,

tighten the union bolts to the specified torque.

CAUTION

!

The seal washers should be replaced with
new ones to prevent fluid leakage.

Tightening torque
Brake hose union bolt (b): 23 N·m (2.3 kgf-m, 16.5
lbf-ft)

• Bleed air from the brake system after installing the

caliper. Refer to “Air Bleeding from Brake Fluid Circuit
in Section 4A (Page 4A-4)”.

• Check the brake fluid leakage and brake operation.

WARNING

!

Brake fluid, if it leaks, will interfere with safe
running and discolor painted surfaces.
Check the brake hose and hose joints for
cracks and fluid leakage.

Front Brake Caliper Disassembly and Assembly

B940H24206005

Refer to “Front Brake Caliper Removal and Installation
(Page 4B-3)”.

NOTE
The right and left calipers are installed
symmetrically and therefore the disassembly
procedure for one side is the same as that for
the other side.

Disassembly
Brake caliper

1) Remove the brake pads. Refer to “Front Brake Pad

Replacement (Page 4B-2)”.

2) Remove the pad spring (1).
