Rear End
Hey everyone I know this might sound dumb... but my 1991 Z28 305 tpi, runs GREAT and strong for a 305! but the weird thing is sometimes when I try to powerbrake it my brakes dont catch and they tires wont even spin... other times I can get it to spin just fine and leave lots of smoke and posi marks any help please? Also I hear a screeching noise sometimes when I try it.. thanks everyone

Re: Rear End
If you try to powerbrake, what happens if your tires don't spin? You just drive forward? Hold the brakes harder. Even a V6 should be able to brakestand.
Screeching sounds like your tires are smoking. What's the problem?
