Why would you need to remove the cap when compressing the calipers? There is a vent in the cap to release any displaced air from the rising fluid and no fluid should need to be removed as it is a closed system.

As the pads wear, the fluid level will decrease, but this is normal. I have never removed the cap or opened the bleeders while compressing the calipers and never had a problem.

after you lathed the rotor what did you do about honing the rotor? i thought they needed the cross hatching to insure proper break in for the pads.

Just buy rotors, they are mega dirt cheap. Who reuses rotors? I see it all the time yet i dont understand not spending 50-100 on new rotors.

Default Need to Loosen E-brake Cable?

My Haines manual wants me to loosen the e-brake cable, which is a multi-step PITA when replacing rear brake pads. Is this necessary? The OP and commenters did not mention it. My online shop manual does not mention it.

Any advice?

No need to remove the handbrake cables when doing rear pads. The only difference from the front is that you need to rotate the pistons while compressing them.

That sucks! I hate having to rotate caliper pistons. I don't understand why some are engineered that way.

The pistons have to be rotated because they are threaded onto the adjusters for the handbrake. It's a pretty common system for a handbrake and IMHO far less complicated than an internal drum brake.

I suppose if you'd rather not have to rotate the pistons, you could disassemble the calipers and remove the adjusters. This would also leave you without a handbrake of course.

I understand, but I'm sure there's a much easier, cheaper and more efficient way of engineering that setup.
