One e-brake shoe is dragging on wife's '02 Tahoe, and the caliper-bracket bolts are so tight I can't get them off to get to the e-brake.
Took the 'Hoe to the local fix-it shop and asked them if they would at least loosen the bolts, and/or do the rear brakes for me. I got this big speech about how the aluminum calipers on that model will likely warp once they've been removed/replaced during a brake-job, and how I'll therefore need to have new calipers installed. 'Quote' came to $500 just for the rear.
This is my first GM product in many years but I never heard of a caliper issue, and would like to hear if it's true. Anyone?


While I'm on the subject... how DO you get those bolts loose? I tried my impact-driver as well as my socket-wrench with a cheater-bar, but no joy. What's the trick?

Thanks!

 

Was unaware that they were using aluminum calipers. That being said, I have good luck using Kroil which is available only online. Let it soak for at least several hours if not a day. Also you can try a heating and then soaking again.
