I didnt drive the car for almost 2 months because i went on vacation. When i came back the brake pedal was going to the floor and the car was having trouble breaking, then the pedal went back to normal but the brakes got stuck. When you would shut off the car the brakes would slowly release. I took it in to the shop and on the way there only 1 wheel was getting stuck. (right front). I decided to change the master cylinder. Now only 1 wheel is getting stuck (the left front) I also did a full break fluid flush. What could possibly be wrong i need the car running ASAP!!! help!!
ps. none of the break lines are clugged...

Were you able to bleed all 4 corners? It sounds like a caliper is staying shut from corrosion. After replacing the master cylinder is your pedal behaving the same way?

The pedal is back to normal but the left front wheel is now getting stuck before i changed the master cylinder it was the right front wheel getting stuck. I really dont know what it could be....

Pete@ECSTuning

You can take the caliper out and off the car and inspect for corrosion or a torn boot. There is really only 1 moving part in a caliper which moves the rest of the assembly - have a look!

Check the caliper pins. They can get corroded. They need to be cleaned and lubed with caliper grease

well i drove the car today and the brake was only getting stuck a little bit but the ABS light is on now... and the pedal is a little soft but not too much... i dont have a vag com any suggestions on what it could be?????????? helpppppp

A wheel speed sensor, which you will need vagcom to know which one. If you have a laptop with a USB connection you can use VCDS lite (demo VAGCOM) in conjunction with USB OBD II Diagnostic Cables so you can know what is going on with your car! For thirty bucks you'll get a lot of peace of mind.

Have you visually inspected anything yet pertaining to your brakes? It could be an obvious fix!

Ok well I'm gonna check the speed sensors is there any particular way of checking them?? Also is there a possibly it could be the abs pump? ( I dunno what it is called... It's the metal block looking thing that has black metal lines coming out of it and it on the left side of the car by the master cylinder)

Just have a look for obvious cracking, corrosion, or dimpled sensors. They pull out of the knuckle with a little bit of force and some wiggling, but be sure you don't crack them when doing so. Patience is key here.
