Howdy!

Short and not-so-sweet - ABS warning light and terrible brake grab happened as I was pulling into my garage. I had been warned they were close to going, but had no idea that close!

So I have already put new rotor on driver side:



and now I go to work on getting the new brake pads installed and the inside piston seems frozen!



I was able to get the outside piston in ok; but that inside one just won't budge. As you can see in the above photo I have the brake fluid drained - I thought that would relieve the pressure allowing both pistons to go in easily. I've tried using a very large wrench to fit inside the piston and push it in, but no go.

I really don't want to mount the caliper back on the hub(?) - I fear I'll risk damaging the new rotor.

So what is the right way to fix this situation? I'm not looking for the easy way, I'm looking for the right way. Should I pull the new rotor off and put the old back on? Is this where I went wrong in the process - I should have changed the pads first, then the rotor?

Thank you for the guidance.
