Which statement describes the hydraulic brake system principle for a non- servo drum brake?
A. Actual braking force at the wheels depends on mechanical force.
B. Application force is multiplied hydraulically by the wheel cylinder.
C. Actual braking force at the wheels does not depend on mechanical force.
D. Application force is multiplied hydraulically by the operator's foot.
Answer (1)
In a hydraulic brake system, the force applied by the driver's foot on the brake pedal is transmitted through hydraulic fluid to the wheel cylinders. At the wheel cylinder, this force is magnified due to the difference in piston area between the master cylinder (where the initial force is applied) and the wheel cylinder. This magnified force then pushes the brake shoes against the drum, creating the braking force.
