Rain coming so I thought I would explore my rear brake again. The CB750 is 509 lbs dry. It has a real good rear brake, for not being hydraulic. I'm sure I could lock the rear wheel easily. The XS, it really sux. There is not that much difference between the brakes on both bikes that I can tell but I haven't matched spec to spec. All Jim's work and others, getting a good set of shoes, matching, centering and getting the dimple in the right direction, well if one heads over to the TECH section, the XS doesn't have a rear brake. There ain't jack. My hub was smooth and not tapered and all seemed like factory. I just can't get my head around making a bike with a rear brake this bad. Under a few items, my bike is still stock and I plan on keeping it that way. The factory manual (74-77) has only a few more sentences than our Tech section along with wear limits. It would be interesting to hear what you other non-hydraulic, un-modified, rear brakers have to say? Might ought to hunt up Jim's and others rear brake work and slip it into the Tech Brake section because doing all that looks like the best it's gona get with the stock setup. I figured the brake would take a "set" and get better after a few miles. 1800 miles and it's still takes a good amount of pressure to tell it's doing anything. I drive far enough down the road, with engine braking and down shifts, I'm always light on the brakes. But If I needed all the braking I could get, and NOW, I feel I would be stubbing my toe on the pavement before I got much out of that back brake. The adjustment nut is tight as I can get it without it dragging. Shoes are just making light contact. So maybe Jim's setup is as good as it's gona get.
