Time to figure out my braking system. I have two old and crusty rear pressure regulators. I'm going to tear them down and refurbish one. I noticed that their adjuster screws are set at different depths.
Is there a way to determine proper preload? Thanks. George |

Take note of how many threads are exposed so you can put it back together the same way . Better yet, send it to PMB for a rebuild.
