● Remove brake pad pin
●Remove brake pad
●Remove spring
●Remove the front brake mounting bracket
●Remove the piston with compressed air. The method
for removing piston is as follows:
○Install a rubber washer and a board with a thickness of
10mm (0.4 in.) or more in the middle of the caliper
○Inject the compressed air into oil port slowly, and pull
the piston out when the piston touches the rubber
washer.
WARNING
To avoid serious injuries, do not put your fingers
or palms in front of the piston! Otherwise, the
piston may crush your hands or your fingers
when the compressed air is injected into the
caliper.
●Take out the dust ring and seal.
Notes
Except brake pad and disc brake, other brake
parts can only be cleaned with disc brake fluid,
isopropyl alcohol or ethanol. Dot not clean the
above parts with other liquid. Gasoline, oil or
other gasoline distillates may corrode rubber
parts. If oil spills onto any part, it will be difficult
to clean thoroughly and eventually corrode the
rubber parts inside the disc brake.
Remarks
○If compressed air is not available, remove the piston
from both calipers as follows (connect brake hose to
caliper).
○ Prepare a container to hold the brake fluid.
○ Press the brake lever until the piston is pushed out of
the brake cylinder, and then remove the caliper.
