Ok so I had the problem yesterday of getting the TRE out because it wouldnt turn. Well now I'm putting new rotors on the girlfriends A4 and CANNOT get the damn caliper carriers off. Both sides the 17mm bolts are not budging. Again sprayed the **** out of them with PB blaster and have even tried banging the wrench with a hammer. NOTHING. Any suggestions on what to do before i invest in a torch?

 

Get a long breaker socket wrench or take your lug wrench from you wheel well and slide it over you current socket wrench for leverage. I had to use the lug wrench on mine when iinstalled my Wilwoods and works great. Just be careful not to hit your knuckles on the car/floor like i did!

 

yeah i thought about that but there really isnt too much room in the wheel well....

 

it will fit, try differnt extensions and you will only need to move the bolt a little bit to free it.
