Question

what are the two types of drum brake assemblies?
a) duo - servo
b) fixed anchor
c) leading - trailing
d) floating anchor

Explanation:

Drum brake assemblies are classified based on their design and operation. The duo - servo drum brake assembly uses the force of the brake application to enhance braking power. The leading - trailing drum brake assembly has one shoe that leads (in the direction of wheel rotation) and one that trails, each with different braking characteristics. Fixed anchor and floating anchor are not the two main types of drum brake assemblies in terms of the fundamental classification of drum brake designs.

Answer:

A. Duo - servo, C. Leading - trailing
