I was wondering if someone could help me/give me some advice with an issue I am having with my car listed above eco boost 6 gear car? The clutch pedal recently went to the floor and wouldn’t come back up. I took it to a garage that have changed the master cylinder, the flywheel, put a new clutch in, checked everything to do with the clutch like the spring, blown the pipe and that holds its pressure. They have replaced 4 slave cylinders but everytime they try to add the hydraulic fluid again the Slave cylinder blows. They are at a loss to what it could be. Please if anyone could help I am desperate I need a car for my sons hospital appointments.

Good evening,

You have air trapped in the lines and it must be bled correctly.

I attached the procedure below for you.

11. After waiting approx. 30 sec., check the operation of the clutch again. If reverse gear engagement is still excessively noisy, repeat the bleeding procedure.

If they did not follow that procedure, it will not work.

Please explain what you mean by the slave cylinder blows?

If they did then either the new slave or master is no good.

It can only be those 2 things causing this issue. My bet is on the air in the system.
