Fitted all new slave cylinders on the bus last week as I had NOS ones and they had shit themselves and leaked..
Drove it for a few days and everything was great, nice pedal feel ,as I had adjusted the brakes, well on the cruise today I noticed that the pedal got hard and eventually I had to stop as the brakes were stuck on. on all 4 wheels????
I backed them off and everything was O.K. again, I had fitted a new master cylinder last year but I think it might be knackered and not allowing the fluid to return and so locking the brakes on .

Anyone have any other ideas.

Cheers
Dave

is the pushrod to long, which wont allow the piston to return home to fully uncover the return port .get them stuck on again then remove the p/rod and see what happens if nothing release the pressure fitting in the side of the mc and if all is good again then mc is knackered

ya gotta have free- play @master/push-rod !!

Will try,Thanks all

Cheers

Dave i had exactly the same problem, and yep, now you have new cylinders the rod will now be too tight, i scratched and scratched my head for ages when it happened to me, then i realised DOH!, haha, good luck

I will adjust it tomorrow and let you know.
Been too busy latley to have a look.
Thanks again.
