Calibration

CALIBRATION

• Prepare the vehicle in running order and position it on a flat surface with the wheels on the ground to set the suspensions.

1. Loosen the brake force distributor rod fastening screw.
2. Apply a 3.5 kg weight (2 kg from chassis no. 2039142 and 4030708) for versions with rear drum brakes or a 8 kg weight (7 kg from chassis no. 2039142 and 4030708) for versions with rear disc brakes to the rod eye.
3. - Keep the rod in this position and tighten the fastening screw to the prescribed torque.

20 ÷ 25 Nm
2.1 ÷ 2.6 kgm

BRAKE SYSTEM AIR BLEEDING

• Fill the brake-clutch fluid reservoir to the max. level with the prescribed fluid.
• If required, remove the relevant wheel.

1. Fit a clear pipe to the bleeder valve. Place the other end of the pipe in a bowl containing the prescribed fluid.
2. Loosen the bleeder valve and press the brake pedal repeatedly (waiting a few seconds between presses). When fluid without air bubbles flows into the bowl, press the brake pedal fully and tighten the bleeder valve at the prescribed torque.

4 ÷ 6 Nm
0.4 ÷ 0.6 kgm

BRAKE SYSTEM PIPES

TESTS AND CHECKS

• Check the pipes and hoses are not enlarged, cracked or rusted. Check there are no leaks.
• To replace a pipe, drain the brake-clutch reservoir with a syringe and close the pipe ends to avoid dirt from getting inside the system.
• After refitting, bleed the air from the brake-clutch circuit (see specific chapter).

Never bend nor twist pipes.

HANDBRAKE WARNING LIGHT SWITCH

REMOVAL/REFITTING

• Disconnect the (-) battery terminal.
• Remove the central oddment tray (see GROUP 70).

1. Disconnect the switch electric connection.
2. Remove the fastening screw and remove the switch.

NOTE: Bleed each wheel separately.

IMPORTANT: Check that during bleeding operations the fluid level does not drop under the minimum level. Never re-use the fluid discharged during this operation. Make sure the fluid does not drip on painted parts to avoid damaging them.
