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 |

There is a thread with related information but no procedure though... (IMG:style_emoticons/default/dry.gif)
http://www.914world.com/bbs2/index.php?sho...225728&st=0 I find this graph on post #40 of interest for what the you are hoping to achieve. But as mentioneed, one would need a way to put pressure on the valve and meaure it with a gauge to dial in the graph numbers.  |
