Remove:
- Front Caliper [C] (see Caliper Removal)
- Brake Pads
- Front Caliper Assembly Bolts
- O-rings
Using compressed air, remove the pistons. One way to remove the pistons is as follows.
Install a rubber gasket [A] and a wooden board [B] more than 10 mm thick on the caliper half, and fasten them together with a suitable bolt and nut as shown. Leave one of the oil passages [C] open.
Lightly apply compressed air [D] to the oil passage until the pistons hit the rubber gasket. Block the hose joint opening [E] during this operation if the caliper half has the opening.
- [F] Bolt and Nut.
- [G] Oil Passage sealed by Rubber Gasket.
- [H] Push down.
Warning! To avoid serious injury, never place your fingers or palm in front of the piston. If you apply compressed air into the caliper, the piston may crush your hand or fingers.
Pull out the pistons by hand.
Remove the dust seals [A] and fluid seals [B].
Remove the bleed valve [C] and rubber cap [D].
Repeat the previous step to remove the pistons from the other side of the caliper body.
Notes:
- If compressed air is not available, do as follows for both calipers coincidentally, with the brake hose connected to the caliper.
- Prepare a container for brake fluid, and perform the work above it.
- Remove the spring and pads (see Front Brake Pad Removal).
- Pump the brake lever until the pistons come out of the cylinders, and then disassemble the caliper.
