2000 Caliper piston rusted

[jesilvas]

Got a pass rear piston inside a caliper that had rusted pushed out and wore out the inner pad and chewed on the rotor.
Anyway, replaced all four rear pads, greased slide pins, had to get two new slide pins cause the other one snapped off in the caliper bracket, so got a new caliper braket
Can I use something like this - BrakeBest® 15215 - Disc Brake Caliper Repair Kit | O'Reilly Auto Parts
Will that help with the rusty piston? Can I replace just the piston? Or just the whole caliper?

I'd replace the caliper if it were me.

[jesilvas]

I probably will. But just didn't know what options there were. I've never really knew much about calipers.

[dhanna6powerstroke]

The way I look at it, it's still an old caliper. By the time you remove and rebuild it you could have already replaced it and been done.

Everything but the rotor is new at this point

[dhanna6powerstroke]

Oh, I didn't see that. Thought it had new caliper bracket.

[jesilvas]

I meant everything but rotor and caliper.
Have new slide pins, boots, caliper bracket, pads.
Just saying I was gonna grease pins and replace bad pad/pads. Turned into this. My life.

[dhanna6powerstroke]

I know exactly what you're saying.

Depends on how much money you have, how much a caliper is, and whether you want to rebuild it! Lol
The seals should be all you need. Pull the pistons out, hone bores, and LIGHTLY sand the pistons. On reasembly, use a light coating of grease on the outer dust seal.

Caliper is only 50ish.
I'm fine with rebuilding, but is that all that's involved? How do you hone the bore?
