Caution! Do not remove the secondary cup from the piston since removal will damage it.
Check that there are no scratches, rust or pitting on the inner wall [A] of each master cylinder and on the outside of each piston [B].
★ If a master cylinder or piston shows any damage, replace them.
Inspect the primary cup [C] and secondary cup [D].
★ If a cup is worn, damaged softened (rotted), or swollen, the piston assy should be replaced to renew the cups.
★ If fluid leakage is noted at the brake lever, the piston assy should be replaced to renew the cups.
Check the dust covers [E] for damage.
★ If they are damaged, replace them.
Check the piston return spring [F] for any damage.
★ If the springs are damaged, replace them.
Check that relief port [G] and supply port [H] are not plugged.
★ If the relief port becomes plugged, the brake pads will drag on the disc. Blow the ports clean with compressed air.
