Slide new brake shoes into the brake caliper a fasten with the screw [5].
Tighten the screw to 10 Nm and mount the locking screw [4].
Mount the rear wheel and actuate the foot brake lever until you can feel the
pressure point.
– It is very important to keep the brake disk free from oil and fatty matters.
Otherwise, the braking effect would be strongly reduced.
– After assembly, check if circlips have been fitted correctly.
– After working on the braking system, one must always actuate the hand
brake lever or foot brake lever, respectively so as to ensure that the brake
pads will lie against the brake disk and the pressure point is established.

Refilling the rear brake fluid reservoir (50 SX) *
Remove the screws [1] and take off the cover [2] and diaphragm [3].The brake
pistons must be pushed back to their basic position. Fill DOT 5.1 brake fluid
(e.g. Motorex Brake Fluid DOT 5.1) up to 10 mm under the upper edge of the
reservoir.
Remount the diaphragm, cover and screws and actuate the foot brake lever
until you feel the point of pressure again. Wipe any overflowing or spilled brake
fluid off with water.
– Actuate the foot brake lever until you feel the point of pressure again.
– Never use DOT5 brake fluid! It is based on silicone oil and of a
purple color. Seals and brake hoses must be especially adapted to it.
– Store brake fluid out of reach of children.
– Brake fluid can cause skin irritation. Avoid contact with skin and eyes. If
you get brake fluid in your eyes, rinse with plenty of water and consult a
doctor.
– Don’t let brake fluid get in contact with paint, it is an effective paint remover.
– Use only clean brake fluid taken from a tightly sealed container.

Replacing the rear brake pads (50 SX) *
Dismount the rear wheel (see "Dismounting the rear wheel").
Press the brake shoes apart with a suitable screwdriver to allow the brake
pistons to return to their basic position.
Remove the locking screw [4], unscrew the screw [5] and pull the brake shoes
out of the brake caliper.
Checking the rear brake pads
(50 SX)
The brake pads can be inspected from the rear. The thickness of the linings
may not be less than 1 mm (0.04 in).
At their most worn point brake pad linings should not be thinner than 1 mm,
otherwise they could lead to brake failure. For your own safety don’t put off
having your brake pads changed.
If the brake pads are replaced too late so that the lining is partly or entirely
worn, the steel components of the brake pad will rub against the brake disc,
thereby imparing the braking effect and destroying the brake disc.
