Bleeder valves

I need to bleed the disc brakes on my '72. Bleeder valves are stuck...any ideas on how to break them loose. 6 pt socket started rounding them off. Should I just get them off and replace the valves? Anyway to save them? Replaced front brakes and have no front brakes now...frustrating.

Re: Bleeder valves

heat them up with a torch I also have good luck hitting them with a hammer to shock them than wrenching them out but you will need to replace the bleaders hope this helps you out

Re: Bleeder valves

Soak with some good penetrating solvent over night, then heat the caliper around the valve with a hand torch. Spray again while hot being careful not to start a fire or breathe the fumes. A cycle or three of that should help immensely. Like Fuzzy said above rap it with a hammer. Also try to work the bleeder back and forth - tighten & loosen etc ...
If that doesn't do it your local shop may have repair kits. You (or they) basically drill out the stuck valve, re-tap new threads, then install a new over size insert which has a new needle seat built in.

Re: Bleeder valves

calipers are pretty darn cheap and sometimes it is better to just get a new pair so you have all new brakes to start off with

Re: Bleeder valves

I think cdowns hit your answer.If the bleeders are that bad then the calipers probably could stand to be replaced.

Re: Bleeder valves

Thanks I'll try the suggestion and buy new if needed. I thought about heating, but wasn't sure if it would ruin any o rings I hadn't thought of.

Re: Bleeder valves

There is always that chance. I have removed countless stuck bleeders that way. One has to be smart and not cook the whole caliper.

Re: Bleeder valves

I used a brazing tip on my torch to concentrate the heat. I see Vautozone has rebuilt calipers for $12+ $10 core charge.
