A disc brake includes: an inner pad and an outer pad; a pressing device configured to press the inner pad and the outer pad against a rotor, the pressing device including a first presser member and a second presser member that are movable parallel to a rotational axis of the rotor, and a frame that is a frame-shaped rigid body and is movable in the direction parallel to the rotational axis; and a housing mounted on a non-rotating body, the housing holding the pressing device, the housing including a pad pin that hold the inner pad and the outer pad so as to be movable in the direction parallel to the rotational axis, the pad pin being held by the housing at both ends of the pad pin in the direction parallel to the rotational axis.

A disc brake assembly for a wheel of a transportation vehicle having a brake disc and a brake caliper support for holding a brake caliper with friction brake pads. To reliably reduce corrosion of the brake disc, a bimetallic plate is provided on the disc brake assembly, wherein a sacrificial anode is secured on the bimetallic plate. The bimetallic plate adopts at least two positions, depending on the temperature of the bimetallic plate. In the first position, the sacrificial anode rests at least partially against the brake disc and, in the second position, the sacrificial anode is at a distance from the brake disc.

A method of forming a B.sub.4C layer as a component of an oxidation protection system as component of oxidation protection system on a carbon-carbon composite material may include forming a liquid mixture comprising a boron-compound and a carbon-compound. The method may further include applying the liquid mixture on the carbon-carbon composite material. The boron compound may comprise boric acid (H.sub.3BO.sub.3). In various embodiments, the carbon-compound comprises phenolic resin. In various embodiments, the method further includes heating the carbon-carbon composite material after applying the liquid mixture on the carbon-carbon composite material to from a boron carbide (B.sub.4C) layer.

The invention relates to a disc brake (1) for utility vehicles, having a brake caliper, a brake disc (37), an actuating lever (4) arranged axially to a disc brake axis (A) of the brake disc (37), an adjusting device (36) comprising an adjusting spindle (12), a pressure collar (13) and an adjusting spindle head (27), wherein the adjusting device (36) is arranged at least partially within an interior (7) of the brake caliper (2), a primary seal (8) for sealing the interior (7) of the brake caliper (2), an annular space (10), which is delimited by an inner wall (6) of a through-opening (19) of the brake caliper (2) and the adjusting device, and a secondary seal (9) for at least partially sealing the interior (7) of the brake caliper (2), characterized in that the primary seal (8) and the secondary seal (9) are designed as a piston protection cap (14).

In a method for producing a brake disc for a motor vehicle, a base disc, which is made of cast iron or aluminum in particular, is provided and equipped with an anti-corrosion layer. The anti-corrosion layer is applied using a wet chemical or galvanic method.

A disc brake and an adjuster system for a disc brake. The adjuster system may include a piston, a chamber, and a wear adjustment mechanism. The wear adjustment mechanism may be located within the chamber. The chamber may contain lubricant for lubrication of at least part of the wear adjustment mechanism.

A system, and associated method, for reducing oxidation of a friction disk may include a braking assembly comprising the friction disk and a conduit coupled to the braking assembly, with the conduit being in selectable fluid providing communication with the braking assembly. That is, the conduit may be configured to deliver inert fluid to the braking assembly, thus reducing the concentration of oxygen in the vicinity of the friction disks and thus reducing/mitigating oxidation of the friction disks.

Corrosion inhibiting hydraulic fluid additives, kits, and methods are disclosed. The hydraulic fluid additive may be adapted for use with brake fluid in vehicular brake systems. The kits may include an additive, a hydraulic fluid tester, and/or correlated information on test results and hydraulic fluid service actions.

A brake rotor assembly is provided. The brake rotor assembly includes a brake rotor portion formed from a first material.
