Front Driver Disc stuck?

[muddpile]

Since I'm doing a full resto, I decided while I was at it, I'd replace the master cylinder. It leaked a little, and was so rusty you could hardly tell what it was. I bought one from the parts store, hung it on the firewall, hooked up the proportioning valve and brake lines, and bled the prop valve with the little screw on the front. I then bled the remaining brakes until clean new fluid came out (I basically flushed the system. Now, the problem is that the front drivers caliper is now clamped down tight, no movement. The other three brakes are fine, but that one is now stuck. Should I open the bleed screw and use a C-clamp on the piston to clean out more fluid from the caliper and see if that's the problem, or is there another thing that might be wrong? Thanks!

Sounds to me like you might have rust or dirt inside the caliper bore itself, that will cause the caliper to freeze in place. IMHO Id go ahead and rebuild both calipers on the truck, its hard to tell just how much crap is still in those calipers even with new fluid in them. Just my .02

Open the bleeder, & see if that frees up the wheel, You could have a collapsed hose. L

crazy is right, if the brake frees up when you opent he bleeder, then it's a hose that failed internally.
However, my money is on rust and crap in the sylinder.
While rebuilding them is cheap and not all that complicated, I think I'd just replace it with a new one.
