Transmission and brakes
Clutch grabbing or performing inadequately
IRREGULAR CLUTCH PERFORMANCE OR SLIPPAGE
Possible Cause Operation
Faulty clutch Check that there is no grease on the masses. Check that the
clutch mass contact surface with the casing is mainly in the
centre with equivalent characteristics on the three masses.
Check that the clutch casing is not scored or worn in an anom-
alous way
Insufficient braking
INSUFFICIENT BRAKING
Possible Cause Operation
Inefficient braking system Check the pad wear (1.5 min). Check that the brake discs are
not worn, scored or warped. Check the correct level of fluid in
the pumps and change brake fluid if necessary. Check there is
no air in the circuits; if necessary, bleed the air. Check that the
front brake calliper moves in axis with the disc.
Fluid leakage in hydraulic braking system Failing elastic fittings, plunger or brake pump seals, replace
Brakes overheating
BRAKES OVERHEATING
Possible Cause
Operation
Rubber gaskets swollen or stuck Replace gaskets.
Compensation holes on the pump clogged Clean carefully and blast with compressed air
Brake disc slack or distorted Check the brake disc screws are locked; use a dial gauge and
a wheel mounted on the vehicle to measure the axial shift of
the disc.
Defective piston sliding Check calliper and replace any damaged part.
Braking vibrations or noise
VIBRATIONS OR NOISE WHEN BRAKING
Possible Cause
Operation
Brake disc slack or distorted Check the brake disc screws are locked; use a dial gauge and
a wheel mounted on the vehicle to measure the axial shift of
the disc.
