FRONT BRAKE CALIPERS
OVERHAUL
• The caliper must be removed for this operation.
• The complete caliper assembly must be changed if
the bore shows any signs of scoring.
DISMANTLING
• Remove rubber dust cover.
• Push out the piston with compressed air, inserting
a block of wood between the caliper and piston to
prevent the piston from being dam.aged. The
piston must not be re-used if the skirt is scored.
• Use a flexible strip of steel with smooth round
edges (like a feeler gauge) to extract the
rectangular section seal from the caliper groove.
• Change all worn parts and reassemble.
REASSEMBLING
• The piston must never be hammered or forced in
as this would damage the seal.
• Lubricate the caliper bore, groove and the new
seal with clean brake fluid.
• Mount the new seal and the piston, pushing the
piston in by hand.
• Coat the piston skirt and the space between it and
the bore with grease.
• Mount a new dust cover.
• Fill the caliper with brake fluid through the bleed
screw aperture to make the bleeding operation
easier.
Remove the bleed screw, tilt the caliper from side
to side during filling to release any air, then
remount the bleed screw.
Attach the hose to the caliper using a new copper
washer.
