Title: Clutch sticky pedal
Post by: bertyboy on November 05, 2016, 10:21:38 AM
Hi I have experienced my clutch pedal not returning fully on a return run from Spain. It did this for a period of two days. I was able to hook it back with my foot. On going to the Ford agent they could find nothing wrong. There were no fluid leaks that they could see. Although I took out an extra warranty they now claim that in the event they drop the gear box to inspect the cylinder the warranty will not cover this unless they can prove that this is the offender and if it isn't the cost is down to me. Has anyone experienced this and if so what was the answer.?

Such faults are usually to do with defective seals on either the clutch slave cylinder (within the gearbox) or the master cylinder (behind the clutch pedal). Master cylinder is preferable as it's not a gearbox out job to replace it! There is a return spring on the cutch pedal as well but if it's an intermittent fault it's very unlikely to be anything to do with that. If the garage checked for leaks I assume they would have made sure the fluid level and condition was ok. If it's behaving itself for now then you could just see how it goes but it's always a worry as there must have been some underlying issue to cause it, the problem is a garage can't diagnose a fault if it's not present at the time of test!

Thank you for your answer insanitybeard. I have read your answer and that is basically what the Ford agent said. Although I took out an extended warranty they will not agree anything until the gearbox has been removed and it is proved to be the slave cylinder. If the agent is wrong then the cost of removing said gearbox etc. is down to me. As it occurred on my return trip from Spain and hasn't happened since it would seem it is to do with the heat generated over a long journey. Does this make sense? At the moment it seems to be ok but might have to bite the bullet and have the ''box'' dropped before undertaking any long journeys.

As the fault is intermittent I seriously doubt they will find a fault just by looking at the slave cylinder,so you are in a catch 22 situation.
Can you suggest leaving the car with them and authorise one of the techs to use car for a few days in hope it faults for them?

When I worked at Vauxhall I used to take customers cars home and basically use them if they had faults that I could not recreate on a road test at work,and then if they played up you could confirm there is a fault and go from there

Thanks for reply Johnny have in fact been driving it for over a week now on short runs
 up to 30 miles and not experienced it happening again. I can only think that it is heat related as it has only happened on long trips of 200 miles plus.

Have you had the system blead to eliminate fluid issues? Brake fluid is hygroscopic so attracts moisture and loses its hydraulic properties that become more evident with high temperatures causing it to be compressible.
