I have an 2.4L Audi A6 multitronic 2007 model which is binding rear wheels. I have had the master cylynder changed, discs cahnged, both rear calipers changed, rear break pads changed and the boost also changed. After all this work, I am told by the mechanic working on the car that the car at times does not break at all. At first it was binding, but now I am told the brakes are not holding in certain instances. What could be the problem and how do I resolve it?

Hi joelalthomas, if they replaced your brakes and you never even made it home they had better warranty the work and as for the "it was a common problem on 2002-2004 trucks" well check for Chevy recalls as this is a safety issue that would have been corrected at no expense to the vehicle owner, do a little more research my friend and let me know what happens, I will check around a little as well in the meantime I would find a new garage.Do not pay any more as you said your brakes worked fine until they worked on it good luck to you As for your 4x4 did you look at the left side when you did the right side? and were they bled off properly? you can visually check to see if the calipers are functioning

SOURCE: How To Change Rear Brake Pads on Audi A6 2006

Remove the tires, Remove the calaper bolts, (small heads on them 12mm or so) Remove calaper, Pads are setting in a holder. Lube new pads with litheum grease and place in holder. (look at old pads, one or both may have small metel tab on one end) If the new pads have the tab, put that pad where the old pad with the tab was. (ie. tab to the inside) Press pistion in with a 'C' clamp. If it won't go in easly, it may screw in. If the parking brake cable is hooked to the calaper, it probly screws in. Use large pliers to screw in calaper piston. Place calaper over pads and install bolts (lube bolts) Rember to pump brakes befor driving . to get a solid peddle.

Ouch, I suggest you check the fluid level of the transmission. If the fluid is OK, you need to ask around about a good gearbox repairer.

you cant check the Transmisson oil by yourself it is located under the vehicle. you will need a hoist to lift it up and then go by the transmission and check it there.
