DISASSEMBLY SERVICE POINTS
When disassembling the disc brakes, disassemble both sides (left and right) as a set.
<> PISTON BOOT/FRONT BRAKE CALIPER PISTON REMOVAL
CAUTION
Blow air little by little to remove the piston. The piston will rush out if a force of air is applied suddenly.
Place a piece of wood, etc. against the caliper body as shown. Blow compressed air through the brake hose to remove the piston boot and piston.
<> PISTON SEAL REMOVAL
CAUTION
Do not use a flat-tipped screwdriver or similar tool to remove the piston seal. These may damage the inner side of the cylinder.
1. Remove the piston seal with your finger tip.
2. Clean the piston surface and inner cylinder with alcohol or brake fluid DOT 3 or DOT 4.
INSPECTION
^ Check the cylinder for wear, damage or rust.
^ Check the piston surface for wear, damage or rust.
^ Check the caliper body or sleeve for wear.
^ Check the pad for damage or adhesion of grease, check the backing metal for damage.
PAD WEAR CHECK
WARNING
Always replace both brake 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 unreliable brake operation.
If there is significant difference in the thickness of the pads on the left and right sides, check the sliding condition of the piston and slide pins.
Measure thickness at the thinnest and most worn area of the pad.
Replace the pad assembly if pad thickness is less than the limit value.
Standard value: 10 mm (0.39 inch)
Minimum limit: 2.0 mm (0.08 inch)
