A brake assembly including a first brake piston; a second brake piston; and a parking brake assembly. The parking brake assembly includes a power transfer mechanism and a motor providing power to the power transfer mechanism. During a parking brake apply, the power transfer mechanism provides the power to both the first brake piston and the second brake piston so that both the first brake piston and the second brake piston are moved until a resistance of the second brake piston becomes higher than a resistance of the first brake piston. The power transfer mechanism then transfers the power from the second brake piston to the first brake piston so that the second brake piston ceases to move and additional power is supplied to the first brake piston.

The aim of the invention is to ensure a reliable lift of both brake pads of a floating-caliper brake (1) after releasing the brake. This is achieved in that a lifting part (20) is hinged to the brake caliper (2) at a hinge point (21), and the lifting part (20) is supported on the support structure (7) at a contact point (23) at least partly at releasing the floating-caliper brake (1), wherein a lift drive (22) is provided which rotates the lifting part (20) about the hinge point (21) such that a support for the lifting part (20) is produced on the contact point (23), whereby the hinge point (21) and the brake caliper (2) are moved.

A disc brake caliper has a caliper body arranged straddling a brake disc having a rotation axis defining an axial direction and opposite friction surfaces, pads accommodated in the caliper body, a cylinder forming a cylindrical wall and a bottom wall, a piston, and a parking-braking system having a rotating member accommodated within a rotation housing formed in the bottom wall. The cylinder defines a first annular housing and a second annular housing both made in the bottom wall, and extending in a direction transverse to the axial direction and leading into the rotation housing. The second annular housing is distinct from the first annular housing and positioned in a direction opposite to an inner surface of the bottom wall. The first annular housing accommodates a first seal. The second annular housing accommodates a second seal. The first and second seals act between the rotating member and the bottom wall.
