Brake bleed screws - ZR-1 Net Registry Forums

I've been trying to get the bleed screws opened on my 91. They've never been opened before. I've tried soaking them with liquid wrench, but no luck. Any other suggestions?

You could try heat, but I'm not so sure that's a good idea. I'd be a little worried with hydraulic fluid as it can burn, though not like gas or something. I'd think they'd come loose eventually, maybe try a 6-point socket or box wrench, and tap it with a hammer to try to jar it.

I doubt the ones on my '90 had been opened before, the car had 21k on it and black brake fluid. But they loosened up without too much trouble.

Replace the calipers and rotors with C5 calipers and rotors. Don't mess around with the stock inadequate stuff. Just my opinion...

You can try some heat...but not too much...rubber doesn't do well with heat. (obviously). You may need vice grips to get them out...of course you'll have to install new ones then...

Take a pencil torch and warm the bleed screw and area around where the screw enters the caliper. Then take a plain ordinary candle and melt the wax into the threads. Give it a few minutes and try to open it again. Wax has very small molecules and will get into places many other products will not and it is cheap.

Thanks for the suggestions. I'm going to try applying a minimal amount of heat and see what happens.
