Provided is a caliper unit for a brake of a vehicle, in particular, a compact caliper unit capable of reducing a size, a weight, and a production cost of a component and improving fuel efficiency. The caliper unit for the brake includes an inner pad and an outer pad, which press both surfaces of a disc to generate braking force, a torque member fixed to a vehicle body and coupled to be movable forward and backward so that the inner pad and the outer pad press the disc, or the pressing of the inner pad and the outer pad to the disc is released, a caliper housing including a cylinder to which a brake hydraulic pressure is applied and a reaction force support part configured to press the outer pad to the disc, and a piston installed in the cylinder and moving forward and backward depending on a state of the brake hydraulic pressure applied to the cylinder to press the inner pad to the disc. Each of the inner pad and the outer pad has a circular shape, and a contact surface of the piston, which is in contact with the inner pad to press the inner pad during braking, has a circular shape.

An improved brake assembly having brake pads that are biased against a rotor using a caliper. Caliper mount brackets bolt to the caliper and hold the brake pads in position. The caliper mount brackets receive and retain replaceable contact plate inserts. The contact plate inserts contact and support the brake pads within the brake assembly. The contact plate inserts each have a first plate and a second plate that extends from the first plate at a perpendicular. The caliper mount brackets receive and retain the contact plate inserts in positions where each first plate and each second plate are positioned to support the brake pads when installed within the caliper mount assembly. The contact plate inserts are harder than the back plates of the brake pads. Accordingly, the contact plate inserts are not rapidly worn by the brake pads and can last much longer than do the brake pads.

A braking system that includes a translatable braking mechanism selectively engageable with a wheel assembly, one or more artificial muscles contacting a support plate and disposed adjacent the translatable braking mechanism. Each of the one or more artificial muscles includes a housing having an electrode region and an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair positioned in the electrode region of the housing, the electrode pair having a first electrode and a second electrode. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region, expanding the expandable fluid region thereby applying pressure to the translatable braking mechanism, inducing frictional engagement between the translatable braking mechanism and the wheel assembly.
