I'm a big fan of drum brakes, especially on trucks. They can take more damage from rocks and debris than disc brakes can. A small pebble can disable a disc brake caliper !I do hate to hear that. I'm sure you are
correct but I like drum brakes.
The sad reality is that disc brakes are cheaper to make and have greater stopping power without brake fade then drum brakes. So every manufacture has gone to them now. Even the big boy "over the road" semi-trucks have gone to "air powered disc brakes" . Really cool to see and easy to work on, but sad it's to see the drum brakes go.
