- Braking Power:
- Drum brakes are often said to apply more force due to self-servo effect. However, they suffer from inconsistencies and brake fade. Disk brakes, though slightly less powerful, offer more consistent performance, cool down quicker, and are less prone to pulling to one side.
- Pedal Force:
- The force required at the pedal depends more on whether the brake system is power-assisted or manual, as well as factors like the master cylinder piston bore size. Neither system inherently requires more force.
- Maintenance and Costs:
- Drum brakes may last longer between replacements due to more friction material volume. However, they often need more frequent adjustments and maintenance. Disk brake components require precise machining, making them less tolerant of errors but easier to service.
- Resistance to Corrosion: In regions with road salt use, drum brakes may exhibit better resistance to corrosion as most moving parts are internal, unlike the exposed components of disk brakes.
