    Bleeding Brakes Problem - Bleeder Screw Stripped

    Guest-only advertisement. Register or Log In now!
    Hello Everyone,

    Over the weekend my friend and I tried to bleed my brakes, since they haven't been done in 2 years, and ran into an issue. We were trying to loosen the "vent screw" (The screw you loosen to actually get the fluid out of the brakes) on the front passenger side the actual head got ripped off:

    Picture #1:


    Picture #2:


    Anyone have any ideas on how to get this out?

    We tried using a screw extractor, but no good the screw is in there. Luckily we didn't loosen anything, so no fluid is coming out and we were able to successfully bleed the brakes from the other 3 points (The rears and driver's side we bled successfully with no issues), but ultimately I'd like to get this screw out for future bleeding or brake maintenance that may arise.

    Also, since we were able to get the other 3 brake points bled, is there anything really "bad" about leaving the passenger side as-is without a flush?

    If anyone has any ideas, please let me know. Thanks!

    Yes, you will probably have air in your lines as you are supposed to bleed.. in this order. Back passenger, Back driver, passenger, driver.

    Probably a little bit of heat and some vise grips. If that fails, you may need to weld a bolt head onto the remaining portion of the bleeder to get it out. Worst case would be drilling it out and retapping the hole. I don't think you'll get that far though.

    Replace the caliper with a reman part. A caliper is not very expensive, and will save a lot of time and hassle. BTW, the rubber caps help prevent the bleeders from seizing in the calipers by keeping water out of the bleeder screws. If the caps are missing, replace them.

    According to rxrep's post in the following thread you bleed our brakes in reverse, i.e. driver front, pass front, driver rear, pass rear.

    I'm with Diagnosticator here on buying another caliper. But I see you have a painted caliper, so a reman won't match, and any high heat or flame would torch the paint. I would give it your best shot with a set of vice-grips, and don't be cheap on the brand, get the real ones. The cheap ones will slip. And remove the caliper from the car so you can get it in a vice or hold it on a bench so its easier to work with.

    If it fails, then do a reman or used, and paint to match.

    On the bleed order, it's traditionally longest brake line -> shortest brake line from the reservoir. So it would be Right (passengers) Rear -> Left (drivers) Rear -> Front Right -> Front Left. I'd like to know why they should be bled in the reverse order. Remember they drive on the 'wrong' side of the street over there.

    You should be able to get a bleeder screw off with an ez-out

    BTW, had the same thing happen to me on both sides, but the bolt snapped flush with the caliper. Had to order some new ones

    It really doesn't matter which order you use to bleed the brakes. Bentley states one way, "standard" practices suggest the opposite. What matters is that you do it approximately every 2 years. Be sure to include the slave cylinder if you have a manual. Hands down, the easiest method is with a Motive Power Bleeder or similar.
