Got my rear calipers back from PMB. They sent a couple of splined adjuster screws? I assume these go in the back side of the calipers and engage the few teeth you can see looking down the hole? Once in you turn them to adjust the clearance on the inner pad. Before I screwed this up thought I would check with the experts. Wonder why they didnt put them in as part of the rebuild.Thanks

PMB has an assembly video on their site.

Thanks. Will check it out

Also videos on bedding pads etc. you can also find them on YouTube.

Probably part of their assembly process.
You need to "exercise" after assembly.
PMB rebuilds everything we do. But I have one of those "gears" welded to an allen driver so I don't have to look for it on the floor when it falls out after adjusting.
They just drop them in the box so you have them.
