Brake bleeding problem.

Recommended Posts

OK, now in my quest to get my Mk3 back on the road I need to bleed my brakes, because a while back the seals on the reservoir leaked the contents all over the servo. I fitted new seals and put some fluid back in the res' to stop the seals drying out and cracking. Today I go to the lockup, get the car out of the garage, with it's binding brakes, 'cos it's stood for so long. I get my new Eeezibleed kit the wife bought for me a couple of years back and hook everything up. Off comes the back wheel and I crack open the bleed nipple................... nothing. I open it a bit more, still nothing! I take the nipple out completely and still nowt! I blow through the nipple and it's clear. I have a prod around inside the hole on the cylinder and guess what? Nothing! Time to delve deeper into the system I think. I back off the pipe union connecting the right side to the left and fluid starts coming out! So in the end, I refit everything and do the usual, put it away cos' it's a job for another day! Now has anybody got any ideas as to why the fluid isn't getting through the brake cylinder to the bleed nipple? The brakes were fine when it passed its last MOT in 2014 and it's only been rolled out of and back into the lockup on various occasions since then!

If fluid is going into the cylinder & back out ,then the across axle pipe must be blocked/squashed. If there's no physical damage try blowing through it ( an airline would be best) try both directions.

If it was going in but not out then I'd have suspected wheel cyl was blocked..

Yeh, it's not the pipe across the axle because, as I said, it's coming out of the drivers side when I undo it and that's the one with the bleed nipple. No damage to the pipe since leaving the MOT station which is only 2.3 miles away from the lockup, therefore I'm thinking it must be a seized piston in the cylinder. :rolleyes: :unsure: I was kind of hoping it would be something a bit simpler. Mind you, I have a new set of springs for the rear shoes, so a strip down is called for anyway.

Ah I thought you ment fluid was at pass side but not drivers.

See if both pistons move but it does sound like it's seized.

Agreed.  Pop the pistons out of the brake cylinder and check the fluid flows.
