Hi,

Can anyone help re: Audi Allroad brakes.

Problems started a while ago when right hand front caliper seized (pistons were stuck) and brakes started to lose feel.

I fitted new caliper, and overhauled the rest. Bled the brakes over an over again, even used VAGCOM to run the pump, but still it had the lack of feel and pulled to the left.

Finally today got round to fitting new master cylinder, bled again and again with VAGCOM, pressure bleeder, even directly on the pedal, but I couldn't belive the brakes were exactly the same.

While it was up on ramps, I wedged the brake pedal, to the point where the brake lights come on. I was confused, I could move the front right and rear left (same circuit), but the other two, front left and rear right were biting. Apply further pressure and you could start to feel the other circuit starting to work, but the others would be locked. The circuit does eventually lock too, but not at the same time.

I know all the calipers are free, even the slide pins.

It seems the original caliper seizing may have been a symptom of something else failing.

Anyone have any ideas? Please help! I need to be sorted, as it seems to be getting worse.
