I was bleeding my calipers and the bleeder broke just below the hexagonal part on the rear right Ate caliper . This is a rebuilt caliper intalled only last summer by a supposed reputed service station belonging to a national chain. Since it is recommended to change the brake fluid every two years, I am surprised that after only one year this one gave me trouble.

The Volvo dealer sells the bleeder for a litttle over ten dollars canadian and so does UAP NAPA. The bleeder for a VW Ate caliper of the same vintage looks exactly the same except that the hexagonal part is 7 mm not 8 mm and costs me $1.10 at another auto parts chain ie: Canadian Tire

I tried putting vinegar and later Liquid Wrench in and around the stud of the broken bleeder.... in vain. My vise grips bite the metal away but there is no movement out of the hole. WHAT SHOULD I DO ? Try to drill out the bleeder hoping not to wreck the inner thread or just forget about bleeding that caliper until it needs to be changed - this will be probably after the car has fallen apart from the salty winters

I had no problem whatsoever with the other rear caliper which was changed at the same time.Is there any risk in using a VW bleeder on this Ate caliper.I have an old bleeder retrieved from a factory intalled caliper. I tried the VW bleeder in this old caliper and it works fine. Is there any risk of galvanic reaction. I am wondering if that is what happened in my one year old rebuilt.
