Liberty Rear Disk Brakes for A-Body
73 & up brakes. Yes I agree. Shaving brackets down to 0.100 ? It's your family your putting at risk. The money you safe can go towards a upgrade on a casket.
I think you’re being a bit overly dramatic. The original backing plates for the OE drums on these cars are 11 gauge. That’s .1196” thick.
Now, they were
designed to be that thickness, which is an important distinction because obviously the Liberty mounts were designed to be thicker for some reason. Although that reason may not just be strength, we don’t know. So that doesn’t necessarily mean machining them down to .1” makes the whole thing a death trap. The bracket mounts just like the original backing plates do.
I don’t like it either, but that’s just an opinion so far. I don’t think enough information, or pictures of the final machined brackets, have been posted yet to make a good determination on the viability of that modification. Certainly not on a long term basis. I’m no big fan of Ehrenburg, but I don’t imagine he’d hang his *** out quite that far. Because if it was truly that dangerous he could be liable for any accidents.
What is the brackets original thickness?
Based on the pictures in the article, the original bracket looks at least 3x as thick as that in the area where it’s being machined. But no measurements are given in the article, and there’s no clear picture showing the finished machinework on the bracket either, just what’s shown in picture #7 in the first part of the article. Which is a detail that should have really been included in the article, there’s still a lot of explaining you’d have to do to when you take those parts to your machinist. They didn’t paint a very clear picture of the modification. And it’s an important one!
Like I said, I’m not impressed so far. I’m not saying it won’t work, but I’m not at all sure it’s worth the effort compared to using the kits that are already out there and proven.
