What are the advantages of disc brakes over drum brakes?
MAINTENANCE:
Fewer moving parts. Compare the caliper with one moving part, to a drum brake, with between 9 and 12 moving parts.
Longer life due to fewer moving parts and more effective heat dissipation.
Friction pads are easily accessible for replacement or inspection.
Easy access to caliper for cleaning and maintenance.
Entire caliper can be removed for maintenance without removing rotor and hub. (Kodiak’s caliper components can be replaced at any automotive parts store stocking GM replacement parts.)
Entire rotor can be removed for maintenance* without removing hub.
PERFORMANCE:
Calipers are self-adjusting to eliminate unequal braking from one side to the other, resulting in smoother braking. Brake adjustment headaches are eliminated.
Braking performance is less likely to be affected by dirt, water, or rust contamination.
Much less sensitive to premature lock-up or wheel skid than corresponding uni-servo or duo-servo hydraulically operated drum brakes, or electrically operated drum brakes.
Fade resistant.
VALUE:
Disc brakes represent a better value to the consumer in that they have a lower owning cost over the expected life of the trailer.
