any idea for stubborn brakes
Turbo Mini Forums

Any ideas for brakes which just will not work right and bleed fully! just can't seem to get the air out of the lines. why do metro 4 pots have soo many bleed nipples! i've been though them all onces with a power bleed and then twice with pumping the pedal and still needs two pushes to get the car to stop. grrrrrrrrrrrrrrrrrrrrr
Need to get the car MOTed this week and this will hold me up.
thanks

alrite mate, always work from the furthest point away from the master cylinder back. i personally always do it by hand not with a pump. just get another pair of hands to work the pedal as you go round the bleed nipples. are you holding the pedal down before you nip the nipple back up?

are you remembering to do them one side at a time? eg one side of the caliper at a time, have you got surficient break fluid in your resivior, have you pumped the breaks before bleeding? is everything done up tight and no leaks? have you tryed bleeding the rears as well?

Searching is all you need on TurboMinis

I'm sure i remember you have to bleed 2 nipples at the same time, then the 3rd one on metro callipers.

I'll double check in the metro haynes when i go for a smoke in the garage in a bit.

stupid question but are the calipers on the correct way up? Only say it because a customer came in a few years ago for the same problem

yeah caliper are the right way up, never tryed bleeding 2 nipples at once. If it is leaking i can't find it, i was wondering if it does have a small leak and is drawing in air but i can't find any fuild leaked out. think i will just have to try try and try again. i'll let you know how i get on.

are your rear wheel cylinders leaking?

this can cause the same effect.

my brothers was doing exactly the same and it turned out the seals in the master cylinder were knackerd. Swaped it for another and it bled first time. Sometimes the seals go when new brake fluid is added. Just an idea.

you can plug the rear lines..or clamp if on rubber hose not aeroquip. that will at least show wher the problem is

That sir, is not rust, it is the progressive mass reduction system
