Brakes help needed urgently
karmannghia60 - April 25th, 2003 at 02:10 PM

Lost all brakes last week. No leaks at all. Bled the whole things but no joy. Noticed that there was no pressure at all at front wheels (not sure about backs because I didn't check). Got the master cylinder recondition (bloody bugger of a job to remove and re-install) but same thing. Just no pressure at all at front wheels. What's going on? Urgent advice needed please. Been without a car for a whole week :(

just a wild guess but worth a check under the circumstances-- has a brake line flattened or bent?, when you say no pressure at all does any fluid come out when you open the bleeders & press?

No fluid is coming out when the value is released. Sound like the master cyl. but just got rebuild.:alien

I suspect you haven't got the air out of the m/cyl & it is air locking. If the pipes to the wheels are connected, remove the stoplight switch & have a helper push the pedal down then put your finger over the stop light s/w hole & get your helper to release the pedal. Repeat till fluid is pushed out on the down stroke then re-connect the stop light s/w switch & bleed the brakes as normal. If this doesn't fix it then the "push" rubber on the master cyl piston may have slipped of its groove & is causing leakage on the down stroke.
If you are solo, then you have to suck the fluid out via the bleed nipple furtherest from the m/cyl. The cheapest way to do this is with a 50ml disp syringe minus the needle & a short piece of plastic or rubber tube from the bleed nipple to the syringe. You can buy the syringe from your local pharmacy- just explain what you're doing so they are not suspicious you're going for the Queen Mother of hits!

Thanks. It turned up to be a comb between master cyl, bad wheel cyl & plenty of air. After I fixed everything (a whole day) took it for a drive and the ^%$# master cyl is now leaking inside the car :cry. Looking for another one. Not looking forward to doing the whole thing again

I think I got it sorted out. Looks ok now but will use it for a week or so to be sure then recheck everything. Will let you know if I needed, thanks for your help
