Replacing rear brakes

[yhelothar]

So I'm doing this for the first time. I have a 91 miata.
I found several guides and videos, but I haven't found a video specifically for changing miata's rear brakes.

From what I see, you can only push the caliper piston back on the miata and you can't open it up. I find it really hard to change the pads with the piston merely pushed back.

Also some sources suggest cleaning and scrubbing everything down, while some doesn't mention anything about cleaning. Mine doesn't even really look rusty. Should I still clean it? Would just spraying it with some brake cleaner be sufficient?

The brakes came with a packet of brake grease that it says to place where there are moving parts. I don't see any of the sources mention anything about brake grease. Should I just ignore this?

I'm assuming that you have 4-wheel disc brakes. In which case, it should be just like the front and most other disc brake set up. Remove the lower pin bolt, flip the caliper assembly up, remove the pads, use a C-clamp to push the piston back so the new pads will fit, slap on the new pads, drop the caliper assembly back down, and you're done. Clean everything as much as you can but it doesn't have to be all shiny and new. The brake grease goes between the back of each pad and the metal shim to reduce noise.

Rear discs sometimes require one of those piston retractor tools (c-clamp won't work). I don't know if that is the case for the miata, depends on the parking brake setup (self adjusting parking brakes).

Might want to find out if this is the case.
