Check the brake pad thickness through the caliper body inspection hole.
ITEM | Standard value | Service limit |
Pad lining thickness mm (in.) | 10.0 (0.39) | 2.0 (0.08) |
If the pad lining thickness is out of specification, left and right pads must be replaced as a complete set.
When the thickness difference between the left pad and the right pad is large, check the sliding condition of the piston, the lock pin andthe guide pin.
Remove the guide pin, lift the caliper assembly up and suspend it with a wire.
Be careful not to contaminate the lock pin and the guide pin with grease.
Remove the following parts from the caliper support.
Pad and wear sensor assembly
Pad assembly
Clip
Outer shim
Install the pads and brake cylinder.
Install the brake hose to the caliper.
Bleeder screw tightening torque :
7-9 Nm (70-90 kg·cm, 5.2-6.6 lb·ft)
Fill the brake reservoir with brake fluid.
Bleed the system.
Install the pad clips.
Install the pads on each pad clip.
All four pads must be replaced as a complete set.
When replacing the brake pads, check for deformation. When replacing the guide spring, use a new one or thoroughly clean the used one.
Press in the piston with a hammer handle or the special tool.
Lower and insert the brake cylinder carefully so as not to damage the boot.
Tighten the two guide rod bolts to the specified torque.
Guide rod bolt :
22-32 Nm (220-320 kg·cm, 16.2-23.6 lb·ft)
Front disc brakes should be disassembled separately.
Do not mix right-hand and left-hand parts.
Remove the piston boot/piston.
Blow compressed air into the brake hose seating hole. Remove the piston and the piston boot.
Remove the piston using a plastic hammer handle. Blow air slowly, adjusting the heights of the two pistons to pushthem out equally.
The secondary piston should not be removed before the primary piston is removed completely. Otherwise the secondary piston can't be removed.
Remove the piston seal.
Remove the piston seal with your finger.
Do not use a screwdriver or another tool because it may damage the cylinder.
Clean the piston surface and cylinder using the alcohol or the specified brake fluid.
Brake fluid : DOT 3 or DOT 4 |
Check the cylinder for wear, damage and rust.
Check the piston surface for wear, damage and rust.
Check the caliper body and sleeve for wear.
Check that grease is applied, and the pad and backing metal are not damaged.
Check the pad wear. Measure the pad thickness and replace it if it is less than the specified value.
Pad thickness Specification : 10.0 mm (0.39 in.) Service limit : 2.0 mm (0.08 in.) |
Clean all components with isopropyl alcohol except for the pad and shim.
Install the piston seal.
After applying the specified brake fluid to the piston outer surface, install the piston into the cylinder.
Install the piston boot and boot ring.
Install the guide pin boots and guide pin.
Check the cylinder for wear, damage and rust.
Check the piston surface for wear, damage and rust.
Check the caliper body and sleeve for wear.
Check that grease is applied, and the pad and backing metal are not damaged.
