| | Test results |
| 0 | PRELIMINARY CHECKS | All OK | Problems encountered | Operation |
|---|
| First of all check whether the problem is accompanied by poor braking action. | Move on to Step 1 | There is also poor braking action. | Proceed as instructed in the diagnosis See table F001 POOR BRAKING ACTION |
| 1 | FLUID LEAKS CHECK | All OK | Problems encountered | Operation |
|---|
| Visually inspect for fluid leaks in the braking system circuit. | Move on to Step 2 | 1. Fluid leak detected.2. Component defective. | 1. Retighten the connectors.2. Replace the defective component. |
| 2 | CHECK FOR FLUID LEAKS FROM BRAKE PUMP | All OK | Problems encountered | Operation |
|---|
| Disconnect the non-return valve connector from the brake servo and introduce a pipe cleaner in order to reach the lowest part of the brake servo chamber. Check that there is no fluid in the chamber. | Move on to Step 3 | Fluid in the brake servo chamber. | Replace brake servoOp. 3330D02 |
| 3 | CHECK FOR AIR IN THE CIRCUIT | All OK | Problems encountered | Operation |
|---|
| Check for any air in the braking circuit. | Move on to Step 4 for the 1.4 16v versionMove on to Step 5 for the 1.2 8v and 1.3 Multijet 16v versions | Air in the circuit. | Bleed the air from the system Op. 0010T65 HYDRAULIC BRAKE SYSTEM - BLEED AIR |
| 4 | REAR BRAKE CLEARANCE RECOVERY DEVICE CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the rear brakes clearance recovery device is working efficiently. | End of diagnosis | Rear brake caliper faulty. | Replace the rear brake caliper involvedOp. 3310B36 REAR BRAKE CALIPER (ONE), LEFT OR RIGHT - R.R |
| 5 | CHECK THE CLEARANCE BETWEEN THE DRUM AND THE SHOES | All OK | Problems encountered | Operation |
|---|
| Check the clearance between the shoes and the drum, measuring the difference between the diameter of the drum and the diameter of the brake measured on the centre line axis of the shoes. | Move on to Step 7 | Drum / shoe clearance not correct. | Move on to Step 6 |
| 6 | CHECK THE SELF-ADJUSTING PLAY TAKE-UP DEVICE BETWEEN THE SHOES AND THE DRUM | All OK | Problems encountered | Operation |
|---|
| Check efficiency of the self-adjusting play take-up device between the shoes and drum. | Move on to Step 7 | Fault in the play take-up device. | Replace the micrometric recovery device. |
| 7 | CORRECT OPERATION CHECK | All OK | Problems encountered | Operation |
|---|
| Check that the fault is no longer present. | End of diagnosis | The fault is still present. | Check the operation of the other parts of the braking system (caliper, pipes, brake pump). |
