Inspection After Installation INFOID:0000000004305898
CAUTION:
• Always disassemble the parts and retighten their fitti ngs, if a brake fluid leak is detected. Replace
applicable part with a new one, if damaged part is detected.
• If leak is detected at the connections, retighten it or replace the damaged part.
1. Check brake hose, tube, and connections for fluid leak s, damage, twisting, deformation, contact with other
parts, and loose connections.
2. While depressing pedal under a force of 785 N (80 kg-f, 177 lb-f) with the engine running for approxi- mately 5 seconds, check for fluid leaks from each part of the brake hydraulic system. SFIA1120E

3. Hang cylinder body with a wire, and remove pad return spring,
pads, shims and pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.
Installation 1. Apply PBC (Poly Butyl Cuprysil) grease or silicone- based grease to the shims. Install shims to pads.
CAUTION:
Securely install shims according to mounting direction of pads.
2. Install pad retainers, pad return spring, shims and pads to the torque member. CAUTION:
• When installing pad retainer, at tach it firmly so that it is
not lifted up from torque member, as shown.
3. Install cylinder body to torque member. CAUTION:
Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.
NOTE:
Use a disc brake piston tool (commercial se rvice tool) to easily press to piston in.
4. Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to BR-25, " Compo-
nent " .
5. Check brakes for drag.
6. Install front wheel and tire. Refer to WT-7, " Rotation " .
CLZ25VF
Removal 1. Remove the front wheel and tire using power tool.
2. Remove sliding pin bolt (lower side).
3. Hang cylinder body with a wire, and remove pads, shims and pad retainers from torque member.
CAUTION:
When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.

and torque member as an assembly.
INSTALLATION 1. Install the torque member and cylinder body as an assembly and tighten the torque member bolts to the specified torque.
Refer to BR-25, " Component " .
CAUTION:
Before installing torque member to vehicle, wipe oil and
grease on mounting surface of steering knuckle and torque
member.
2. Install the brake hose to caliper assembly with new copper washers. Align the brake hose tab between the protusions (B)

Check piston surface for corrosion, wear, and damage. Replace piston as necessary.
CAUTION:
The piston sliding surface is plated . Do not polish with sandpaper.
Sliding Pin, Sliding Pin Bolt, and Sliding Pin Boot
Check sliding pins, sliding pin bolts and sliding pin boots for wear, damage, and cracks. Replace applicable
part as necessary.

Brake Burnishing Procedure INFOID:0000000004305914
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:
• Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicl e within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
