I had a leak on my slave cylinder, had slave and master cylinder replaced by professional shop, when I recieved it back there was about 2 inches of clutch, took it back they checked the hydrolic system for air. There was none I regained some of my pedal but not much. Clutch was replaced about 5 years ago. I had fine preasure before the slave cylinder started leaking. What eles could it be. Thanks

The master cylinder needs to be removed from the vehicle and bench bled . Did the shop do this?.

BENCH BLEEDING (MASTER CYLINDER)
With reservoir and hydraulic line attached to master cylinder, lightly clamp reservoir in vise. Fill reservoir. Hold master cylinder vertically, below reservoir. Ensure clutch line quick connect is below master cylinder. Using small screwdriver, depress internal mechanism of male quick connect coupling to open valve. Pump and hold master cylinder push rod. Close quick connect valve. Release master cylinder push rod. Fill reservoir. Repeat this procedure until no air bubbles are present.

They told me they bled the system how they did it im not sure, when I took it back due to the pedal being almost all the way to the floor before engaging, they told me they opened up the bleeder valve several times with no air. After the second trip back to the shop the clutch pedal was better about half way down before clutch engaged.

It is possible there is still air in the system. Also did they set the clutch pedal after repair !.

ADJUSTMENTS
CLUTCH PEDAL FREE PLAY
NOTE:Clutch pedal is self-adjusting. When clutch system is serviced, clutch pedal must be pumped at least 5 times to set tension.

You are correct it is not adjustable. But as it states in my previous post. The pedal must be pumped at least 5 times after clutch service to reset the pedal position !

Thanks for your help I will call and ask them if they did this, im assuming this is something that is done once all the air is bled out of the system.

They should heve done this when they replaced the clutch. And again after bleeding. I have learnt not to assume anything. We tech's are not infallable and do forget things now and then !. Lol.
