New concepts in foundation brake systems have been developed for passenger motor vehicles to meet the growing demands upon vehicle performance, safety and economy including the advent of anti-lock braking systems that require higher operating pressures and load insensitivity.The “pad guided” caliper is a new disc brake which has transferred the housing support function from a pair of guide pins to specially designed backing plates on the pads. This design coupled with a patented slip joint connection between the pads and the housing provides a unique caliper alignment capability reducing brake drag caused by complementary taper pad wear, and/or anchor bracket misalignment.A new integral disc brake has also been developed which incorporates an automatically adjusted parking mechanism based on the principle of a collar locking onto a shaft under an eccentric load. This “lock actuator” integral parkbrake caliper mechanism (1)* is inherently self-adjusting and load insensitive and offers excellent serviceability, reliability, and efficiency.
