Caution:

Do not tilt the brake caliper when removing or install-
ing, or the brake pads could be damaged.

•

Take off the brake fluid reservoir cover complete
with the diaphragme.

•

Add brake fluid.

Caution:

While renewing the brake fluid, its level must not
drop below the MIN mark, or else air will be drawn
into the brake circuit.
If this happens, the brake system will have to be
bled.

•

Connect a suitable vessel to the bled screws on
the brake caliper to trap the escaping brake fluid,
and open the bleed screw by half a turn.

•

Using piston resetting tool, BMW No. 34 1 500,
press the pistons fully back into the brake cali-
pers.

•

Take out the piston resetting tool and insert
spacer, BMW No. 34 1 520.

•

Press the pistons back in the second brake cali-
per, but do not remove the piston resetting tool.

•

Close the bleed screw.

•

Apply the hadbrake lever several times until
braking pressure is felt to build up.

•

Hold the handbrake lever in to maintain the
braking pressure and open the bleed screw,
at the same time pulling the hanbrake lever up
firmly.

Caution:

Do not release the handbrake lever until the bleed
screw has been closed.

•

Close the bleed screw, then release the hand-
brake lever.

•

Allow brake fluid to escape from both brake cal-
ipers in succession until it is clear and free from
air bubbles.

•

Close the bleed screw.

•

Install the brake pads/brake calipers.

Note:

When adding brake fluid, note the thickness of the
brake pads. If the pads are new, add fluid up to the
MAX mark.

•

Brake fluid level = Max mark.

•

Place the diaphragm and reservoir cover back in
position.

•

Tighten the retaining screws without using undue
force.

•

Make a functional check on the brakes and bleed
the brake system if necessary.

Renewing rear brake fluid

•
