I've just put (P reg)rs2000 discs and callipers onto my modded (P Reg)Escort van, they were bought 2nd hand from a local RS centre ,
Since they have been fitted , I can only manage about 60-100 miles before the pedal pressure fades out , i then have to pump them and eventually they fade out to nothing.
I have blead the system about 5 times ( including jacking the back up with both wheels off the floor to help open the valve), replaced the master cylinder with a new one , fit new cylinders on the back , and still the problem persists
W.T.F. am i doing wrong , or have I been sold a dodgy set of calipers?
There are no leaks coming from the system anywhere , its almost like air is being sucked in somewhere.
Can anyone help ?
Cheers
Dave
