break calipers

In this section, we will examine the rear wheel braking system.

Similar to the front wheel, one factor that affects the location of the brake caliper is the geometry design of the car’s rear suspension.

For some cars, there are control arm that connects to the rear part of the wheel hub, which takes up places that can fit the brake, therefore the brake caliper must be located in front of the rear wheel axle. For example the Lexus GS350 with rear wheel steering option, the control arm is located behind the wheel hub, therefore the brake must be placed on the other side.
