Same 1970’s Ford truck as has the fast idle problem. It’s a four wheel drive. One of the front brake bleeder valves is situated in a way that makes it difficult to get a combo wrench (3/8 inch) on it squarely. It has now rounded off so much that the 3/8 inch is of no use. But the next lower one (5/16 inch) is too small. I’d like to remove it and replace it with a new bleeder screw. I can fit a socket over it, and I think I could with that, but there’s no room for the socket wrench to fit.
I’m thinking vise grips directly on the bleeder screw, but I worry it may crush. What if I put a socket on it, then used vise grips on the socket? I’ve already used the stuff that frees up rusted bolts and let it sit 24 hours. No go.
My fall back is to remove the brake line and change out the brake wheel cylinder with a new one, but I’d like to avoid that much work as it involves the four-wheel drive stuff and takes a lot of time. Any ideas?
