Disc vs. Drum
So I've looked through some threads on the subject but couldn't find my answer. I thought drum breaks were going the way of the dinosaur b/c disc breaks have better stopping power and reliability but I was recently at a car show in Vegas (just a show for car dealers showing off 2004-5 models). Now I admit I don't know what trucks use, but I was shocked to see a 2004 PT Cruiser (i think) and another similar size car using rear drum breaks. What's the advantage of drum breaks?

smaller vehicles only need tiny rear brakes - sometimes even small discs can be too much - or they want to same money

Re: Disc vs. Drum

![]() Another aspect to drum brakes is full retraction of the brake shoes from the drum, sometimes resulting in less potential for drag. Disc brakes often rely on hydraulic suction to pull the pads back a bit from the rotor surface. Fuel efficiency goals push automakers to lessen drag as much as they can these days. Having said all that, however, disc brakes are also generally more efficient since they dissipate heat better than drums. This provides more brake fade resistance-- a good thing. Since the front brakes produce the brunt of the stopping force for a vehicle, they are used almost universally on the front end of vehicles these days. Just my 2 cents... Kevin
