DISASSEMBLY AND REASSEMBLY





Lubrication Points

Disassembly Service Points
When disassembling the disc brakes, disassemble both sides (left and right) as a set.

Piston Boot/piston Removal

Protect caliper body with cloth. Blow compressed air through brake hose to remove piston boot and piston.

Caution: Blow compressed air gently.

Piston Seal Removal

1. Remove piston seal with finger tip.

Caution: Do not use a flat-tipped screwdriver or other tool to prevent damage to inner cylinder.

2. Clean piston surface and inner cylinder with trichloro-ethylene, alcohol or specified brake fluid.
Specified brake fluid: DOT3 or DOT4

Reassembly Service Points
>A< Boot/bushing/lock Pin/guide Pin Installation

Lubrication Points On Caliper:

1. Grease parts as illustrated with specified grease.
Specified grease: Repair kit grease (orange)

2. Install the guide pin and lock pin as illustrated so that each head mark of the guide pin and the lock pin matches the indication mark ('G" or "L") located on the caliper body.

INSPECTION
- Check cylinder for wear, damage or rust.
- Check piston surface for wear, damage or rust.
- Check caliper body or sleeve for wear.
- Check pad for damage or adhesion of grease and check backing metal for damage.

Pad Wear Check

Measure thickness at the thinnest and worn area of the pad. Replace pad assembly when pad thickness is less than the limit value.
Standard value: 10 mm (0.39 inch)
Limit value: 2.0 mm (0.08 inch)

Caution:
1. Always replace both pads on each wheel as a set (both front wheels or both rear wheels). Failure to do so will result in uneven braking which may cause an unpredictable vehicle condition.
2. If there is a significant difference in the thicknesses of the pads on the left and right sides, check the sliding condition of the piston, lock pin and guide pin.
