Abstract
An axially, slidable brake disc system employs leaf springs between a hub of a suspension casting or knuckle to float the brake discs for axial sliding movement, while holding the discs against wobbling, and employs brake pads which are biased by springs to float on a stationary bridge so that the contact between the brake pads and discs is a light random contact thereby resulting in reduced residual torque drag and disc thickness variation. The rotating brake discs will shift axially, slightly from the braking position to the off-brake position with the brake pads urged by their spring forces to keep their pad faces parallel to and slightly spaced from adjacent brake disc surfaces to prevent corner engagement and localized rubbing contact thereby reducing pad wear, residual drag torque and disc thickness variation. The brake force applicator may be mounted at a 12:00 position and in an integral bore in the suspension knuckle to reduce the size, weight, and space envelope of the braking system. Less braking pressure is needed with two brake discs and four brake pads and the system will pass the AMS fade test.
