Clutch grabbing or performing inadequately
CLUTCH
Possible Cause Operation
Tear or irregular functioning Check that the masses open and return normally
Check that there is no grease on the masses
Check that the clutch masses' contact surface with
the clutch bell is mainly in the middle with charac-
teristics equivalent on the three masses
Check that the clutch bell is not scored or worn
abnormally
Never operate the engine without the clutch bell
Insufficient braking
BRAKING SYSTEM MALFUNCTION
Possible Cause Operation
Poor braking The rear (drum type) brake is adjusted by regulat-
ing the special adjustment (on the wheel) bearing
in mind that, with the control levers in the rest po-
sition, 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 sim-
ply 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 break-
down, replace
The brake fluid has lost its properties Replace the front brake fluid and top up to the cor-
rect 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
Brakes overheating
BRAKES OVERHEATING
Possible Cause Operation
Defective piston sliding Check calliper and replace any damaged part.
Brake disc or drum deformed Using a dial gauge, check the planarity of the disk
with the wheel correctly fitted or the concentricity
of the rear drum.
