Someone please help me!
I replaced the rear calipers on my 300Tdi (non ABS) about a week ago.
After bleeding the brake lines & replacing all the brake fluid with new stuff with an eazibleed,i found that my brake pedal was going to the floor with a whooshing sound-only to return to firm after a few pumps.
The brake pedal needed to be pumped a few times to regain it's firmness.
I got the wife to pump the brakes while i bled each corner (several times)
manually.This still didn't help and i noticed that with the engine off,the brakes could be pumped to full "firmness" but with the engine on ie. a vaccuum applied to the servo,the brake pedal was at the floor again when pumped.The vaccuum pump is working correctly,the t-peice and associated pipework is o.k,there's vaccuum getting to the non-return valve (which is working properly).
I read through lots of threads and decided a second-hand servo would help...... .WRONG!
After reading a lot more threads,i decided a new master cylinder would be the answer.......WRONG AGAIN!
I still have the same symtoms and am currently waiting for the wife to come home and do the pedal pumping while i bleed....... AGAIN!
Hopefully,all that's needed is to bleed the system now but i suspect that it's not the case.
Could anyone suggest a possible cure in the meantime?
Thanks in advance.
