Insufficient braking
BRAKING SYSTEM MALFUNCTION
Possible Cause
Operation
Poor braking
The rear (drum type) brake is adjusted by regulating the special
adjustment (on the wheel) bearing in mind that, with the control
levers in the rest position, the wheels must turn freely.
The braking action should begin when the brake levers are
pressed by about a third.
Check the brake pad wear.
If it is not possible to remove any problems by simply adjusting
the transmissions, check the brake pads and front brake disc,
the brake shoes and the rear drum. If you encounter excessive
wear or scoring, make the necessary replacements.
Air bubbles inside the hydraulic braking system
Carefully bleed the hydraulic braking system, (there must be
no flexible movement of the brake lever).
Fluid leakage in hydraulic braking system
Elastic fittings, piston seals or brake pump breakdown, replace
The brake fluid has lost its properties
Replace the front brake fluid and top up to the correct level in
the pump
Defective sliding of the cables in their sheathes
Lubricate or substitute
Brake noise
Check the wear of the brake pads and/or shoes
