1G ‘90 rear caliper rebuild parts

[drrotor]

Frustrated after calling ALL the local parts stores looking for caliper rebuild kits for the rear of my early ‘90 GSX. Finally, a NAPA guy came through for me, but the kits he found weren’t even from NAPA. He found them from an outside supplier. The part number is Dorman D352030. These fit the early versions with the 30mm pistons. Once I had that number, I found that eBay has plenty of ‘em available.
Also needed one piston— again, really hard to find. Got the (obsolete) part number from Mitsubishi and eBay came through again- with the supplier in Latvia, of all places… (I couldn’t remember where Latvia was, looked it up. It’s next to Estonia FYI). Waiting for it to arrive. Tracking says it’s “shipped”, so that’s encouraging…

That’s another option for me then. I have multiple sets that I’d like rebuilt.
RTM is also an option as I’ve contacted them recently. I just need to go find them in my stack of parts totes in the shed .

RTM is out of business as far as I know.

Does anyone know if the early FWD’s are the same as the early AWD? My 1990 GST is an October 1989 build date.

I believe the early rear caliper piston is the same as many Toyota Corollas. Toyota part#47701-12030

The 1990 model year AWD rebuild kit, MB857874, is the same kit used for all 1990-1991 FWD models.

The AWD rebuild kit in 1991-1994 was MB857875. This was the same kit for 1992-1994 FWD turbo models.

Remaining FWD models used MB895028.
