KH brake help
I have the official Miller Special Tool Company, special tool, from back in the dinosaur days, in getting pistons out of the Kelsey Hayes, 4 piston calipers.
So it's no big deal at all for me in getting stuck pistons out of their bores, or ones that will easily come out.
Yes i know of that "trick" method, in removing stuck, frozen, rusted, pistons out of their caliper bores.
Pumping them out hydraulically always works, in getting them out.
But for you one piston already came completely out of it's bore.
Then your screwed unless you put that piston back in the bore, and pump away until the frozen one begins to come free.
But your going to have to block the movement of the one that came out, until the frozen one begins to move.
I put the caliper body between the jaws of my bench vise, and open, little by little, until i see the pistons come out equally.
A block of wood i use on the bigger caliper halve's. A 4x4x4 has been working for me.
Then you also say the bleeder screws are also frozen in place.
Then your really screwed.
If you keep trying, and then round them off, you will have to drill them out.
No other way.
How long have these things been sitting, without being in use?
You get them from a rust bucket state?
I don't want to come across as a personal salesman here, in helping you out.
But if worse becomes worse, for you, i have a pair of rebuilt calipers advertised for sale, here on this forum.
