Hi All. Does the "RH Thread" description mean that it only works on a particular side of the car? & if so which side. If not, then what does it refer to. I have NSR binding. Pads are not stuck, so considering next step. Cheers.

It refers to the thread ie clockwise to rewind. It will work in both calipers. Some other cars have an anti clockwise thread (LH Thread) on one side. That's how I've understood it.
