Still full of air

[dixiebabes]

Cant get rid of the air in the brakes bled them again, felt ok then after 2 miles spongy again. Anyone considering changing to 4 pot calipers and vented discs. Have a think before you do it.

A bit wary of putting the old master cylinder on as that will mean putting more air back into the system. So I bled them again today took it out to test em first press of the pedal it travelled further than it should. Seemed ok for a bit took it back jacked it up again and bled them again. No air at the rear but a few bubbles at the front. Took it out again seemed great then with no warning travelled too far again FFS starting to get on my tits this. It's not going to the floor just every now and then travells further than it should???????

I had a similar problem and it was the master on mine. If you don't want to put the old one on then get another (47 quid I think on the flea) and if it turns out to be something else I'll buy it off you because I put an old master onto mine when the original packed up, and ought to replace it, really.

Ok sounds like a plan Adam. Have to be next month though im going overseas. Remind me on when i get back and we can sort something out bud.

Cheers

Are you certain the discs are running true? If they're not then the pads will get pushed back when you drive and it'll feel just like air in the system.

Could be warped discs or more likely just dirt/rust on the disc/hub flanges.

Everything's brand new Martin thats whats confusing me.

update:

Got the car up in the air again and bled all five nipples about 4 times rear first passemgers frobt then the drivers side last. Possible sucess only one spongy press after a quick blast around. When people said tgey are a bugger to bleed they weren't joking. More like a nightmare.

Just a thought mate...Are you just bleeding the fronts?....Ziga

No Mark done the rear as much as the fronts.

Is the fluid level changing in the reservoir over time?

If it is its hardly noticeable. That's whats baffling me.
