Why Do Some Cars Still Use Drum Brakes? Drum brakes lock-up the wheels easier and make better parking brakes than disc brakes.
Those who enjoy doing handbrake turns may also favour rear drum brakes since they lock-up easier (self-energizing).
Drum brakes are also smaller and lighter but these are not reasons why modern cars still use them.
Why are drum brakes so bad? You need to adjust the drums so there is drag, if the wheel moves freely its too loose. Drums are 3 times lighter than discs. Calipers are 4 times heavier than wheel cylinders, and the brake surface area of a drum brake shoe is 6 times larger than a disc pad.
Why do some cars have drum brakes instead of disc brakes? One of the main advantages of drum brakes is that they’re less costly than disc brakes. This is reflected in the cost of the vehicles which choose to use them on some or all wheels. Drum brakes do not require ABS brakes or assistance in the same way that disc brakes do.
Why do a lot of vehicles still have drum brakes in the rear?

What are the disadvantages of disc brakes?
The disadvantages of disc brakes outweigh the advantages; they’re expensive, heavier than caliper brakes, more complicated and raise compatibility issues. Disc wheels are not going to work in your current bikes, and vice versa. There is also the risk of problems with heat dissipation on long descents.
Do rear drum brakes stop the car?
