Whilst attempting to bleed the brakes after fitting braided hoses to my bike, the bleed nipple on the rear caliper was seized and sheared off. Whats the best way to remove it with out wrecking the entire caliper?

--Remove caliper from the bike
--Remove the piston - air blow gun, or grab with a pair of pliars (use a rag so you don't scratch it).
--Remove the seal
--Completly wash and dry it (no brake fluid left)
--Put caliper in vice using "soft jaws" (to prevent scratching).
--Heat around the bleeder valve with a torch
--Then gently try to remove it with an "easy out" (gently, cause small "easy outs" break easily). If you feel the "easy out" twisting, STOP turning, remove it and apply more heat.
--Good luck

good luck getting it out and not having a leak if you do. The caliper is alum and the bleeder is stainless it seals with a taper fit into the caliper and the face is very easily damaged when drilling. If you need to get the air out thake the caliper off and turn it so that the brake line is th ehighest point and crack the line, the air always goes to the top.Be sure to use a spacer when doing this to prevent pushing the piston out of the caliper.

Speedbugg is the daddie. I have recently removed a similar broken valve with screw extractors, long, time consuming job! be patient, tap in the extractor, slight ANTI clock turn, another tap and turn and so one. It would have helped to heat the body of the objects its in, but with a caliper thats NOT an option, rubber seals and all. BEST OF LUCK.

leave it in place and bleed the brakes on the remaining wheel nipples.If that doesn't completely bleed the system bleed the brake with the sheared nipple by carefully backing off the brake pipe line whilst an assistant pumps the brakes don't forget to re tighten the pipeline

Real carefully, take a small screw extractor, and once it is started in the hole, lightly tap the end of the extractor while turning it counter clockwise. If there is not a big enough hole there, take a small drill to get you started. Just don't rush the job, it can be very time consuming, but will save you a lot in the long run...

Get an extractor and get it out. You can get them at any parts store, some may actually loan them out. Before you do it though, spray a little break-free or liquid wrench on it to help loosen it up.

if you cant get it out with an ezy out....get a tap for cutting threads from an engineering supplier. & carefully drill the old bleed screw to the recomended tap size & re tap the hole...you may also be able to drill it out & retap it to the next size bleed screw bigger..... Hitting the old bleed screw with a pin punch first may help in breaking the "seal " on the caliper body...try the Ezy out first It may be your lucky day...

Speedbug got it spot on.

use an easy out (screw extractor) and hope for the best.
