futura 3 Posted February 25, 2007 When I stripped my beam, I discovered that the LH rear caliper beeding nipple had been broken. I drilled it and tried to extract it but broke the extractor in, which meant more drilling. The original thread is still there, but for the housing to match the shape of the nipple for it to seal, I had to use some metal repair epoxy paste. Is it safe to use, or will brake fluid eat the repair paste? Share this post Link to post Share on other sites
lagonda 42 Posted February 25, 2007 Just broken one of these on my front caliper, oh joy. At least it's not leaking. Will try Ezi-out. Be a first if it actually undoes it. Anyway, brake fluid is a pretty good paint stripper, so you are wise to be concerned. Obviously much depends on what is in the filler. Presumably you've bled the brakes successfully. If the area around the nipple is dry, I'd leave it until tomorrow. Then I'd start the engine so the servo's working, & pump the pedal HARD a few times. Then check. If still dry, go for a short drive & do a few emergency stops, go back home & check. If still dry you're probably OK, but would be wise to check again once brakes are thoroughly hot, as heat may increase chemical reaction. If the area around the nipple is still wet it might just be because of recent bleeding. As brake fluid is water soluble, spray the area with water & once that is dry the fluid should have "dried" as well. If it's still wet after that then you do have a problem.

futura 3 Posted February 25, 2007 Thanks for the reply. I haven't fitted the calliper back on but will follow the steps you mentioned Share this post Link to post Share on other sites
dommorton 0 Posted February 25, 2007 I got a 206 gti rear caliper from ebay for £10. Nearly all pug ones are the same and are readily available. Share this post Link to post Share on other sites
sorr 0 Posted February 25, 2007 Given how inexpensive a rear calliper will be it really is not worth taking any risk of it not sealing. Yes you may get the warning light on if the fluid gets low but that is not the point. Brakes are a vital system so do it right and get another caliper.

Grim.Badger 15 Posted February 26, 2007 Make up some more of the epoxy stuff in a jam jar lid and fill it with brake fluid. Leave this overnight and if the epoxy stuff is still absolutely solid (araldite rapid steel is brake fluid resistant and will remain solid) then it should be okay. Saying that I wouldn't use it as a long term option but if you are desparate then it should be okay, it's not like the epoxy is holding anything together.

BuD 0 Posted February 26, 2007 From the description it sounds like the epoxy would have to withstand the fluid pressure in the braking system, if so I wouldnt do it as the pressure could cause it to pop. Share this post Link to post Share on other sites
futura 3 Posted February 26, 2007 Thanks for the replies guys, I'll go for the safe option and get another caliper I got a 206 gti rear caliper from ebay for £10.
