5. A brake system comprising:
a brake caliper;
a brake pad supported by the brake caliper, the brake pad comprises a first pad section and a second pad section; and
a parking brake system comprising a bridge extending across a first side and a second side of the brake caliper, the bridge comprises fingers;
wherein during a parking brake apply, only the first pad section is moved against a braking surface to create a clamping force, and
wherein during a service brake apply, both of the first pad section and the second pad section are moved against a braking surface to create a clamping force,
wherein the first pad section comprises a friction material having a coefficient of friction that is different than a coefficient of friction of the second pad section.
