Test results

First of all, check the type, condition and pressure of the tyres.

Check that the wheel bolts are correctly fastened

Move on to Step 1

1. Tyre inflation pressure not correct

2. Tyres unsuitable or worn

3. Wheel bolts not correctly tightened

1. Make sure tyres are inflated to the correct pressure

2. Replace the tyres

3. Tighten the wheel bolts to the correct torque

Check:

- the condition of the front pads braking surfaces;

- the condition of the rear pads braking surfaces

Move on to Step 2

1. Brake surfaces vitrified or with traces of grease, oil or water

2. Front pads damaged or not the recommended type

3. Rear pads damaged or not the recommended type

Check the condition of the rear brake discs.

Check the condition of the rear brake caliper pistons

Move on to Step 4

1. Rear discs worn or damaged

2. Rear calliper pistons worn or seized

1. Replace the rear discs

 Op. 3310B48 REAR BRAKE DISC (ONE), LEFT OR RIGHT - R.R.

2. Replace the rear brake callipers

Connect the Examiner diagnostic equipment to the diagnostic socket.

Check that there are no faults in the ABS control unit

Move on to Step 5

1. Error detected in the control unit

2. No communication with the control unit

1. Continue following the instructions on the diagnostic equipment

2. Restore connection between the ABS control unit and the diagnostic connector

 See E7020 ABS

Keeping the Examiner diagnostic equipment connected, carry out active diagnosis of:

- pump motor;

- solenoids

Move on to Step 6

Pump and/or solenoids faulty
