Bleeding the brake system (Focus Turnier 1)

Air in the brake system turns each brake into an air pump, so bleed the system immediately, for example after any work that required removing brake hoses or pipes. It is often enough to bleed only the brake circuit in which the work was performed. But to be on the safe side, bleed both brake circuits. ALWAYS use new brake fluid (DOT4 ESD specification - M6C57A) and a clean, transparent synthetic hose (for the windshield washer system or for supplying air to an aquarium). Also, have an assistant assist you. Park your Focus on a level surface. During the entire bleeding process, keep the reservoir constantly filled to the MAX mark. The brake fluid level should never fall below the MIN mark. If this happens, air will enter the system again through the filler holes.



Make sure that brake fluid does not get on the varnished surface. Otherwise, immediately wash the surface with clean water. Otherwise, the varnish will become dull and soon peel off.

Stages of work

Disconnect the connector of the locking cover. To do this, pull back the fastening loop 1 and press down the clamp 2. Unscrew the cover.



Sequence of actions: bleed valve on the left in front - on the right in the back; bleed valve on the right in front - on the left in the back.

Remove the dust caps from the bleed valves and clean the valve nipples.

Slide a synthetic hose (arrow) onto the nipple and lower the free end of the hose into a collecting container with a small amount of brake fluid.



Loosen the bleeder valve nipple a maximum of one turn. Have your assistant slowly press the brake pedal to the floor and quickly release it.



Wait about 3 seconds, the master cylinder should fill again.

Repeat this process on each wheel until no more air bubbles come out of the bleeder valve and clean brake fluid comes out. Keep the brake pedal pressed to the floor.

Close the bleed valve - release the pedal. Remove the hose from the bleed valve, add brake fluid to the expansion tank up to the Max mark.

Fill the expansion tank, screw on the sealing cap and connect the central connector.

Check the operation of the brakes while driving carefully.
