Don't buy S14 ULTRA-POWER rear calipers from rockauto - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I needed rear calipers and I figured I'd be best off buying new.

Rockauto only has new calipers from a brand called ULTRA-POWER their part numbers are 191904 and 191905.

The parking brake won't work on them, minimal resistance in the handle and it won't stop the car from rolling at full engagement as seen from the cam pawl.

They didn't copy or machine the parking brake cam bolt and pill connecting rod properly.

I was able to swap the cam bolt and pill connecting rod from my old calipers into these to make them work.

If you are up for tearing them down and rebuilding them with your old OEM parts its fine.

They are listed as $82 each on rockauto. Best to gamble with reman calipers, at least you have a shot the parking brake will work.

If you don't have usable OEM calipers, remanufactured ones can be a viable option. However, there's a risk that the parking brake mechanism may not work as well as with OEM parts.

Yes, if you are ready to disassemble them and reassemble them with your old OEM parts, it's fine. It's listed on RockAuto for $82 each. It's best to try your luck with refurbished calipers, at least the handbrake can work. It seems worth a try.

I was impressed with the Nugeon reman caliper I bought. I still held on to my stock one instead of turning it in for the core though. Might try rebuilding it (it leaked).
