Brake bleed nipples broken off, now what?


Hello all,
when installing new brake hoses I found that both front bleed nipples were broken off on the calipers.
I dont really like to do all the work to replace them... any ideas for bleeding without using those nipples?

You'll need to get the broken nipples out. Drilling and using an "easy-out" would be my first choice. Make sure you use the largest size easy out that you can. If you break-off (a smaller sized) one it is a real PITA to get the broken piece out.
Replacing calipers is not that big of a job. Pretty easy actually, just expensive...

Thanks Fred, I managed to bleed it somewhat by loosening the connection on the top of the calipers. Brakes work fine now except that the pedal stroke is quite large. Replacing the calipers is the right way, I agree, but I dont have much time or money at the moment. I will probably try to drill out the nipples when I have the time.

So you did not remove the air from the pistons. You might also have a bit of condensation in the fluid, add a bit of heat on that to become steam and you will have no brakes. If you press the pedal a few times, does it rise? If yes you have a lot of air.
As long as you only kill yourself and no-one else fair enough.

Who said I DRIVE the car? I understand what you say, and agree too BTW, but why that TONE? Have any better idea for me? Richard.

If you do not feel lucky enough to try the easyout solution -- I know I suck at it -- you could take the caliper to a trusty machine shop and have them take it out for you.

Hi again,
If you read what you wrote it sounds very much as if you are driving the car. "Brakes work fine now". Therefore the TONE was extremely mild by usenet standards :-)

PS. Replacing the calipers because of broken nipples is not the right way. The chances are by the time you drill the nipple to put the extractor in it will loosen itself.

Charles, the car is my second car, I dont need to go anywhere because I work from home anyway, it was on the lift in someone elses garage, and I needed to get it out of the shop. If you dont like me driving it out then next time I suggest you come over and help me push it out. No, there is no air in the pistons, no the pedal does not stiffen up much and no there is no moisture in the pistons. I just dont like it that I can not bleed the normal way, so will replace the nipples. How did they get it bled last time without the nipples is why I am asking.
Dont you have your own standards? Your statements say a lot about ... you.
