•
Apply a low pressure jet of compressed air to the oi-
lway (E) in which the brake fluid union was fitted in
order to cause the two plungers to be ejected from
their seats in the two halves of the caliper; now undo
and remove screws (V2).
•
Separate the two caliper halves, ensuring that the two
plungers (F) and gaskets (G) do not fall.
•
Remove wiper seal (H) and oil seal (L) in both caliper
halves, taking care not to damage the relative grooves.
•
Check that the plungers and their seats are undama-
ged.
•
Clean the parts thoroughly and flush with exclusively
alcohol.
Always fit new wiper seals and new oil seals. Refit
the plungers, the O-rings, the retaining rings, and
the wiper seals, lubricating the parts with brake
fluid.
NOTE After working on the braking system, always
check that:
• the brake fluid lines are not damaged, cru-
shed, or twisted;
• the disc and pads are not contaminated
with oil or grease;
• all screws and unions are fully tightened;
• there are no leaks from any of the unions.
