Wrenching GM brake pins

Seems to me you answered your own question. Torch it first perhaps give it a shot of PB Blaster let it soak and then hive it heat.

Then remember the anti-seize putting the suckers back together.

Or get a Ford. No pins to mess with, knock one key out and the caliper is loose(some have two keys). Takes about 5 minutes to change pads, longest time is spent jacking the piston back in.

On my 2001 Ranger..remove (2) 15mm bolts from the back of the caliper..and the thing comes off in your hand. Jack the pistons (2) back in with a large pair of Channel locks, put antiseize on the two bridge pins and stick it back on after setting the pads in place. Takes less than 5 minutes..probably closer to 3 if you have an air wrench.

Did both the Ranger and the exes Saturn yesterday afternoon in about 1.5 hours total..fronts AND rears. 8 wheels.

Or buy a set of bolt out extractor sockets. They don't care about rust or rounded bolt heads...

Also the easy way to break GM pins loose is to strike the head straight on with a good hammer. Usually that shock is enough to break the rust free.

My 96 Blazer had allen head bolts.

As did/do my '84 LeSabre, '86 Suburban, '96 Roadmaster, '96 and '99 Saturns, and my son's '96 Firebird. Don't remember what the '78 Cutlass had...

Depends on the make/model. Some are standard bolts, some allen, some torx. Others use a single or dual pin to retain the pads and there are even a few with just clips.
