rear caliper XT 600

**bolla** · #1 8 Sep 2005

Hi
I have managed to snap the bleed nipple off my rear brake caliper.Have tried to remove whats stuck but think I will damage the caliper.
I want to get another caliper sacondhand, does any one know what yamaha uses the same caliper as a XT 600 Tenare 3AJ.
Thanks

I have done the same thing before. A good engineering firm, will easily remove it by brazing a rod to the broken stub, and twisting it out. The heat should break the seal. They can then either fit a new nipple, or depending how the thread is, retap it, and fit an oversized nipple.
Good luck Dave

Alterativly, you can buy a special banjo bolt that includes a blead nipple which you fit in place of the one that holds the brake pipe to the caliper (using new copper washers).
Then blead via this new nipple and forget all about the old nipple - it will still be closed .

Thanks for replys
I have tried to remove bleed nipple by banging a torex drive in and using an impact driver ,its still stuck and now theres nothing to weld to.
The caliper still works and I have bleed brake by undoing banjo bolt.I will get a banjo bolt with bleed nipple but would really like to get the old nipple out.
I have been told not to drill out as if you go to far the caliper will be damaged and wont seal.
I am going to a bike rally at weekend so should be able to pick up another caliper, does any one know what other yamahas use the same caliper?
I also had a bit of play on the rear brake pedal it moved side to side.I was quoted £34 for new pedal, the shaft would also need replacing.
I removed pedal wrapped a bit of tin can around shaft and replaced pedal,its now perfect.
