[Vwdiesel] '01 Golf TDi binding rear brake

[Tony and Lillie]

There are two things that commonly cause a sticking rear brake. One is the 
ebrake mechanism sticking, and the other is the pressure being held 
hydraulically.

The first is usually either the mechanism in the caliper, or the cables 
themselves. I've done both on MK4's, so it's hard to guess which is more 
common. Check by pulling the tires and check if the lever on the caliper 
fully retracts against the stop. You will see what I mean when you get in 
there.

If it's not that, you can usually find the culprit for the hydraulics 
holding pressure. Push the brakes good and hard, then release them. Open the 
bleeders and see if there is still pressure held, IOW fluid squirts out. If 
not, it's a caliper problem. If fluid does come out pretty hard, either a 
line or the master cylinder is not releasing. You can further determine this 
by breaking the line loose where the rubber line meets the hard line that 
comes from the front of the car. Do this in the same manner, push the 
brakes, release, and see if fluid comes out.

HTH,
Tony
