my right rear brake bleeder screw will not move. I soaked it with WD40 for a looong time, multiple "coats", and all my wrench did was strip the head. I tried vice grips, clamped down really tight, all they did was strip it. It's like it's on there real tight, but the metal's too soft for me to give it enough torque to unscrew it. I bought a replacement screw but it ain't doin me any good til I can get the old one off. Any bright ideas?
if i was you i would get a better penitrant then wd40. go to the store and get seafoam DEAPCREAP, or liquid wrench, once you soak it get a special socket for removing bolts with rounded off heads. good luck, sorry if im not more help
Yeah, i've had a really stubburn one before, i soaked it in PB Buster and tapped it for like an hour to let it work in, then i filed down each side so i turned it into a box(another 30 mins) then me and 2 other people clampped down vice grips on it so hard that it left brusies in my hand.... then it stripped.. LOL. So i finaly took it off and the thing that finaly got it to break loose was clampping the end of the bleeder screw in a vice and spinning the wheel cylinder. hope it helps. good luck.
Keep this in mind the next time you toss out those little rubber or plastic covers that go over the bleeder screws. With those on, even cars that have well over 100,000 miles on them don't have stuck bleeders.
Anyway, heat and lubrication are what is going to do the trick here. You should be able to heat it quite a bit and not do any damage. After all, it is a brake caliper, it is designed to take some heat. Use a propane or MAPP torch to heat the screw directly and spray it with Cyclo Break Away or PB Blaster. Toss that WD-40 right in the trash where it belongs. I don't know what that stuff is good for, it is crappy lube and it can't protect worth a chit either. You might as well be using #2 diesel fuel as a lubricant. Heat and lube several times -

Grab it with a pair of Vise Grips while it is still hot after the third or fourth application. It should come out. If it does not, time for a new caliper, some of them can't be saved.

I used PB blaster (got it in my eye too
), but couldn't get ahold of a torch. Cops came by and said I couldn't have my car on jackstands in front of my house any longer so I hadda give it up
. I swear, I don't think anyone ever bled the brakes before I got this thing...the other screws were fine but I don't think this thing's ever been cracked loose...
Oh well, the rest of the brake system is bled, it'll do for now, maybe one of these days when I'm bored I'll borrow a torch or pull the caliper and try the vice technique...
