Sheared off bleeder screw
My fault, sorta.
previous owner shredded the heck out of the bleeder screw, and left me with a rounded nub. I tried vice grips without joy. So I applied some heat, then tried again. Sheared it right off. (Of course.. alloy screw but steel caliper..) Should I even try to drill it and use a bolt extractor, or just plan on a new caliper? Mike D. |

yes - be sure to clean & bleed once repaired BBA |

Mike, the only thing I've ever seen work is drilling it out and installing an over size plug with a bleeder screw in it. See this http://tinyurl.com/5mfo7 Brian |

If it's a popular brand of car, rebuilt calipers will be cheap enough
that all the drilling & carrying on is somewhat senseless. If the bleeder was rounded off then vise gripped & heated & still broke off, that sumbitch is seized REALLY good. Easy outs usually won't affect a cure in these types of situations. Good luck. |

Nope. In over 30 years of wrenching I have never seen an easy out or anything else work on a sheared off bleeder screw. Not to say it 'couldn't' work, I just haven't seen it. Replacement time.

I was cursing bad until I got the price for a replacement caliper. $19.00 not including tax. For that price, I replaced.

How long can you justify farting around with a damaged caliper before you could justify replacing it. Exception might be if you have a rare caliper. I did this to a Fiat 128 some years ago, looked at machining it to remove the bleedcock, and ended up finding a salvageable caliper for near nothing at a junkyard. Would have bought new had it been easily available and cheap enough. |
