what is the best way to remove a froze up brake bleeder screw?

Answer 1

i own a shop and you have to soak it as much as you can with wd-40 or a good rust remover and don't heat it ,it will ruin the wheel cylinder or caliper ,what ever its on don't heat it,if the parts soaker wont work you may have to get another part for it,because most likely it will break off in there,good luck with it i hope this helps.

Answer 4

Is it broken off or rounded off? Heat is the best, but not too much. Heat till it smokes, spray with penetrating lube. Tap with a hammer then try a socket with 6 points. Don't force it as it can break off. If it is on a wheel cylinder and it becomes useless, you will have to replace it completely. Federal law prohibits drilling and retapping except if you do it at your own risk. If you get it loose take it all the way out and clean out the hole. You can buy a bleeder if you want to get rid if the rust.

Answer 5

If you haven't tried already use a 6 point socket. Do all the lube stuff suggested. You can try heat too.

If you've already rounded it off get a tiny pipewrench ~4 inches and it'll do the job. If you don't have one handy a small pair of vice grips may work too.

Just make sure you get a new screw so you can tighten it and get it off next time.

Answer 6

take a deep well socket of the right size put over the bleeder and give it a few sharp smacks with a hammer. this will loosen the rust on the threads and allow easy removal.

Answer 7

clean around the treads with a wire brush, heat the bleeder valve just enough to melt some candle wax around the treads, you can use a propane torch, it just has to melt the paraffin so it can seep down the treads of the bleeder, you may want to tap it with a brass hammer to loosen the rust around the treads, use a six point socket or wrench.

Answer 8

good question thats easy apply a lot of wd-40 and let it soak in a little like maybe 20min or so. if that does'nt work make sure the area is dry and apply some heat to the screw not alot but enough because remember if you break it that means new caliper.

Answer 9

You can try something like liquid wrench and let it set a few hours, be patient while trying to remove it if it breaks off you can try using an ease out to remove it which sometimes works. Failing that the replacement isn't so expensive.

Answer 10

a socket made specially for removing stripped nuts, i got a set from sears for like 15 bucks once, has lasted me years.

its like a regular socket but has counter clockwise spiral edges, so when you put it on it and twist to loosen it grabs tight then pulls back... they work very well on those since it is such a soft metal.

you might try a torch and a brake line wrench first, they work better because they grab more of the nut.
