ROUTINE TESTING
FRONT BRAKE
Pulling in the front brake lever operates the front brake by
pumping brake fluid from the master cylinder to the front
brake calliper. The brake pads are pushed by the calliper
pistons against the front disc. Slowing the bike down.
The braking surface of the disc should be free of oil and
dirt to ensure maximum braking efficiency. If for any rea-
son the master cylinder is empty of brake fluid after chec-
king for pad wear it should be topped up as necessary. If
there is air in the system the brakes will need to be bled.
Loosen the bleed nipple on the front calliper, putting a
petrol tube onto the nipple. This tube should be put in a
recipient so as not to spill brake fluid. Undo the brake nip-
ple on the calliper 1 or 2 turns only and gently operate the
front brake lever so that the brake fluid goes down, until it
comes out through the tube without any air bubbles. At this
point, hold the brake lever in and close the bleed nipple.
Top up the master cylinder reservoir as necessary with DOT
4 brake fluid. Replace the top and check brake efficiency.
