Liberty Rear Disk Brakes for A-Body

RLF Cuda said

I would be good to have some solid information on Green Bearings. Especially how the design changed to improve bearing life. Having a product fail early in its introduction is bad for image. So my experience Early On keeps me from even thinking about them. I would also like Richard Ehernberg's input before I would consider them in any application.

DoctorDiff did a little write up on his blog about the difference in the new “green” bearings, and why the old ones used to fail.

I personally still prefer the tapered bearings. There are pros/cons to each kind, just like anything.

As for Ehrenberg, while I think he definitely has made some really useful contributions, I personally don’t blindly trust his opinions without an independent fact check after his whole “ball joint overangling” BS in his “disk-o-tech” article about using the F/M/J/B/R spindles on an A body. It was total speculation on his part, and he published it without ever bothering to check the actual suspension geometry that results. Of course it turned out he was completely wrong about it, the suspension geometry change you get by using FMJ spindles on an A body are both minor and arguably beneficial depending on how your car is set up.

I’ll have to take a look at the Liberty rear disk conversion. Ehrenberg tends to come off as a bit of a purist (just my opinion), so I’m a little surprised he’s doing a rear disk conversion. Machining brake parts down to a tenth of an inch thick seems a bit marginal if they’re parts that see braking load. But I haven’t seen the coversion so maybe it’s no big deal. I’ll have to take a look at the article.
