145 - MiTo   1.4 16v TJet   HYDRAULIC BRAKE SYSTEM - BLEED AIR   0010T65   

Detail     Detail

This procedure is valid only for the 120 HP version

The air in the hydraulic circuit acts as a pad, absorbing a large amount of the pressure exerted by the master cylinder and reducing the efficiency of the braking.

The air present is felt at the brake pedal, making it seem spongy and reducing the braking capacity.

- Position the vehicle on a lift.

- Check that the brake/clutch fluid is between the MIN and MAX levels.

Use solely the specified brake-clutch fluid.

1. Remove the brake/clutch fluid reservoir cap and connect a suitable equipment to the reservoir.

To ensure the braking system is bled fully, the equipment excess service pressure must be adjusted to 1.0 bar.

1. Remove the protective cap for the bleed valve on the brake caliper.

2. Connect the recovery device (pipe and reservoir) to the brake caliper bleed valve.

3. Open the bleed valve.

- Open the fluid reservoir tap slowly.

- Wait for all the air in the hydraulic system to escape.

- Retighten the bleed valve on the brake caliper to the specified torque.

Whilst bleeding the air, refill the brake fluid reservoir as necessary.

The brake fluid collected should not be reused. The level should always be topped up using new fluid.

If the system is not fully operational after having carried out the bleeding operation, repeat the entire procedure after waiting a few hours for the brake fluid to settle down in the system.

- Remove the vehicle from the lift.

1. Remove the brake/clutch fluid reservoir cap and connect a suitable equipment to the reservoir.

To prevent impurities entering the brake-clutch fluid reservoir, before undoing the cap clean it and the entire upper surface of the reservoir next to the filler thoroughly.

To ensure the braking system is bled fully, the equipment excess service pressure must be adjusted to 1.0 bar.
