HELP brake problems

[croket]

Please help , my brakes have gone soft as **** over night no visible leaks either.

It takes a couple of pumps to get them hard but fades fast and when i stomp them the front right locks.

Ive just bled them and still no better , im at a loss now im not sure where to look now. Only thing i can think of is abs unit faulty but im not getting abs light up . :unsure: Im thinking of pulling the abs relay to see what happens

Did you check inside the cabin against the firewall on the drivers side for leaks?

 

[croket]

No i didnt just looked over the calipers , lines and master cylinder , what would it be leaking from under there ?

Master cylinder diaphragm??

 

[LumpyVR4]

Master cylinder gets my vote. Check where the master cylinder bolts to the booster in the engine bay. Try to think of anywhere the fluid could be hidden from view, like inside a boot. Are you losing fluid from the resovoir? If it is a leak that will confirm it.

 

[croket]

Yeah its slowly loosing fluid but i didnt think master coz it was replaced not long ago , ive got another master so ill try that first . Cheers guys

If its losing fluid its gotta be going somewhere. If it ran out of fluid its going to have air in the system.
You have to get a good pedal and I dont think its to do with the abs.
Good luck

Check the rear calipers too, normally see a lot of them leaking out of the handbrake spindle thing.

Your spot on the money george right rear is leaking from the hand brake bit , cheers for the advice . Lucky ive got some spare rears

Awesome. The years tooling away behind the lathe at Perth Brake Parts has paid off!
