Default Rounded my bleeder screw, ack. What now?

Hey all,

I went to bleed my brakes today and my right rear bleeder screw was a bit stuck. I used the box end 10mm and I had to put a little extra arm in to it. Sure enough, it rounded right off.

So what can I do to replace the thing?

I JUST did brake jobs on 3 of my vehcials. They ALL has bleeded issues. I used a propane torch to heat up the CALIPER (the area around the bleeder) then douched it with PB Blaster. Then I reheated it and clinched on a pair of vise grips with curved jaws. It came loose without too much issue. Just heat it to about 200-250 deg. Thats all it takes.

If you need a little more grip, you can use a dremel cutoff wheel to make small nicks in the edges of the head for the vice grips to grab onto

try a six point socket. may need to clean up the head a little bit but its hard to round a nut or bolt with a six point. If not, as said previously, soak overnight, then use heat and vice grips. Hope you got strong hands. You don't need a new caliper though unless you twist the bleeder in half. A six point or vice grips should be all you need. And get a new bleeder!

You unsrew the bleed screw until it comes out of the caliper. Then you screw the replacement in ......

No! No! No!, You STILL won't need a new caliper if the bleeder screw breaks off.

Just drill out the center of the broken bleeder screw, and remove it with an easy out. Heating it first, like Bill Curlee suggested, will help the easy out break it loose.

You can buy a six corner box end wrench from Sears. I only use six corner on bleed screws............way to easy to round off the corners on those puppies. Also agree that PB Blaster is great, given a little time to work, on breaking loose, rusted bolts and screws.

Almost any parts store will carry the speed bleeder screws, or a similar named screw. They have a check ball built in to make bleeding a one man job, you just crack them and then go and pump the brake pedal, they won't backflwo because of the ball valve.

Cost is about $20 for all 4.

Don't worry too much about heating them or torquing on them to get the old one off. They take a lot more heat and abuse than that on the track

If we have misunderstood, and you damaged the threads in the calipar, then I think the best thing would be new calipars. They are all the same, you can get non-z06 and just paint them.

Wow....you must do some serious driving to get your brakes to 2000 degrees. Just using a propane torch, you have to be careful...

So in other words.......do worry about it...

You nailed it. I never have backed out a bleed screw all the way, so I wasn't sure if it came out all the way.

Thanks. I bought a pair of speed bleeders for the back and gonna find a store with the fronts.

Are the back bleeder screws different from the front?
When I bled my brakes, I used the same wrench on all of them????

As far as I know they are the same for front & rear speed bleeders.
