Trouble Replacing Front Brake Pads!!!

Trouble Replacing Front Brake Pads!!!
I am trying to replace the front brake pads on my 1994 Toyota Pickup. My first problem was getting the calipers off due to rust. I was finally able to get them off with a little PB Blaster and banging on the wrench with a hammer. Now, I cannot get the cylinder in either caliper re-compressed. I was able to get the driver side caliper compressed some, but not enough to get it back on. It took A LOT of effort to turn the c-clamp I was using to compress the cylinder as much as I did, and I cannot compress it any further. In fact, I will have to get a new clamp since I broke the one I was using while trying to compress the cylinder. I don''t remember compressing the calipers ever being this hard on any other vehicle. Is there a trick to Toyota calipers that I am unaware of? I really hope that the calipers are not done for. Any help will be greatly appreciated.

x2 i had the same proble when i did mine, if you take i to shucks, give them your old core and they will give you a new about $50 per side

While it sure sounds like a stuck caliper, before you trade them in you might disconnect them from the brake line and then try to push the caliper in. I had a different make truck where the flex-line clogged inside; you couldn't push the caliper in because the fluid had nowhere to go.

Make sure the cover is off the master cylinder.
Also, rent or borrow a proper caliper compression tool.
It works way better than a c-clamp. I think cause it presses evenly.

If the caliper is fully removed from the vehicle, lines and all, and the pistons will not compress rather easily- should realistically only take a few pounds of pressure to do get the caliper piston moving, your choices are to either rebuild or replace the caliper.
Personally, I'd rather replace the caliper.
New/rebuilt calipers come with warrantees... rebuild kits do not.

My $0.02:
I've done this job a few times. Aftermarket (rebuilt) calipers are so cheap that I just replace them. At about $30 apiece, I can't justify spending the time it takes to rebuild them (BTW,I did rebuild them the first time).

After a little closer examination, I figured out how to get the cylinder to compress. Originally, I was putting the old brake pad against the cylinder and compressing the c-clamp against that to help distribute the pressure a little more evenly. Right before I started taking the caliper off to replace it, I tried eliminating the use of the brake pad and put the end of the c-clamp down into the cylinder. It compressed with ease. I guess the pad was pushing against something that would not let it go anywhere. I really wish I had figured this out before I put so much effort in, but I am glad I got it. Thanks for the input from everyone.

if it gave you resistance with the pad in place... is it going to release from the rotor when you let off the pedal?
...just a thought: it may be 'slow' to compress but you should be able to push the piston in with your fingers. If you need a c-clamp to compress it, I'd still contemplate replacing them.
