Do a quality turning on them and tru arc some quality shoes to fit them, and they were very impressive even if they were still on that land yacht Buick.
Getting rid of drums on the front made such a huge improvement that the makers found that they could get by with leaving the drums on the rear, because they had a minimal effect.
In the fifties when the mid level and high level cars, e.g, Buick, Olds, Cadillac, Mercury, Lincoln, etc. started getting really heavy, the drums really started being marginal. I remember my Dad ca. 1956 invested in a quality drum lathe and a TruArc machine. He would turn the drums and the use the TruArc machine to fit some quality shoes to the drums. If one were to simply use normal wear to make the shoes fit the drums, they would have hot spots and would not break in as effectively. He had a reputation in town as being someone who could do a really good brake job.
A few years back I was at a Friday night cruise where a young fellow had a well done rat rod. I made a comment about the Buick brakes on the front and he asked me how I knew that they were Buick brakes. I didn't really know how to answer the question. He said that they did work really well. Of course the car probably didn't weigh much more than 2,000 pounds.
Another set of superior drum brakes I remember were the ones I put on my '69 Roadrunner. These were relatively light cars with components meant for heavier cars. When it came brake time, a friend of mine at a local brake and alignment shop told me that he would make a set of great brakes for it for nothing.
I took him the drums and shoes. He took scraps of quality lining material and riveted them in place on the shoes in three sections per shoe with about a 1/2" between each section. He then turned the drums and Tru Arced the shoes to fit the drums. When I got it all back together I was amazed. Up until that point I had never owned a car with better brakes. I don't think I ever did until my new 240D in '77.
Like anything else, there are good and bad within the category. I still prefer disc brakes hands down, but there are some drums that are better than others.

My first auto was a 1964 Chevrolet Chevelle.
A factory option for these cars was sintered metallic brake lining.
I did not know this when I got the car. I would have added them at the time were it possible.
Most consumers did not know or care about this option. Few were sold with them. And front discs were still about 3 model years ahead, for GM to offer.... |
