I searched this board and only came up with one mention of Praise Dyno Brake/Muscle Car Brakes.
Here is my experience with their products.
I have a 56 210 with a six and a glide. When I got the car in 1994 the brakes had recently been serviced with fresh shoes that were good factory replacements. I had them checked and adjusted right after I got the car as a precaution. All was as it should be.
I live in Houston and traffic is a mess. People cannot drive here. This car was not fun at peak traffic times. Stopping was on a wing and a prayer. Freeway driving was out of the question.
After driving the car in limited amounts and only when there was little traffic and after about two years I lost a wheel cylinder. Rather than patch the brakes back together I decided I needed an upgrade but could not afford a disc conversion. I had read about Praise Dyno Brake, which is now Muscle Car Brakes (same owners just new name), and called them up.

I had it installed and the drums turned. They were well within spec for thickness.
That was about 12-14 years ago if memory serves. I've driven the car about 13,000 miles since then and I can tell you this.
This one upgrade took the car from frightening to drive in traffic and on the freeway to no worries at all.
She stops straight and true with no lockup. I had at least three different panic situations ranging in speed from 35MPH to 60MPH and every time I was able to confidently avoid a wreck.
Discs are much better. No doubt there.
But for those of you who either want drums for originality or simply don't want or have the money to spend on a disc conversion this is the way to go.
