Leaky Brake Caliper (on a GOlf)

I would pop over to one of the VAG forums, bet there is a trick to it.

But if your clamp was leaking air a bit it could be anywhere. The resi didn't run low did it?

No resi always up near the max and the bottle on the easibleed also was at least 3/4 full at all times.

Worst case seems to be if there is air in the ABS system then it needs some VAG COM process to follow to clear it (dealer job...). I've posted up on a few VW forums too, but they ain't half as helpful or quick to respond as the SEers!

John,

I know of some systems that use a single rear brake line - it's possible (but improbable) that there's air been introduced to this single rear line and that the other side needs bled.

Thanks Mac - sounds possible. I've been told that there's a balancing valve on the rear brakes which means that I need to bleed both rears at the same time, so I'll give that a shot. I have already bled both rears independantly but that didn't make any difference.

Wish me luck!

If you can find the balancing valve then giving that a tap whilst bleeding can also help.

I have to admit though - I only use presure bleeders for 80% of the job and leave the last 20% to the old fashion method where I can play around with the bleed screw to get the last wee bits of air out.

WHen you say the old fashioned method, do you mean pushing the brake pedal and then opening the bleed nipple, closing the bleed nipple, and lifting the brake pedal back up?

The pressure bleeder i'm using effectively does just that, but removes the need for someone to sit in the drivers seat while i play with the bleed nipples on the calipers. Anyway, I'll be having another play tonight to try and get to the bottom of the problem!

Thanks

John
