A slack adjuster assembly and systems, components, and methods can comprise a sensing piston assembly that includes a housing, a piston slidably provided in the housing, and a biasing member provided in the housing. The biasing member can be configured to bias the piston away from an end wall of the housing. The piston can have an end wall opposite the end wall of the housing, where the end wall of the piston can have at least one orifice that extends from a first side of the end wall of the piston to a second side of the end wall of the piston.

A brake system for a motor vehicle, having a first hydraulic brake device configured to brake wheels on a first axle of the motor vehicle, a first control unit configured to control the braking operation of the wheels on the first axle; and a second hydraulic brake device configured to brake the wheels on a second axle of the motor vehicle, and a second control unit configured to control the braking operation of the wheels on the second axle. The first control unit is coupled with the second control unit via a communication channel. The first control unit and the second control unit are each configured to receive data that are relevant for the control of the braking operation, the first control unit furthermore being configured to transmit a data signal on the basis of the received data via the communication channel to the second control unit.

A simulator valve includes a housing having a pedal simulator passage and a master cylinder passage extending therethrough. The master cylinder passage is located longitudinally between the first housing surface and the pedal simulator passage. An armature is located at least partially within the housing for selective longitudinally reciprocating motion with respect thereto between first and second armature positions. A poppet is located within the housing for selective longitudinally reciprocating motion with respect thereto between first and second poppet positions. The poppet defines a first valve and a second valve the poppet includes a poppet bore extending longitudinally therethrough and selectively occluded by the first valve. A damped flow fluid path selectively permits fluid communication therethrough from the master cylinder passage to the pedal simulator passage. A free flow fluid path selectively permits fluid communication therethrough from the pedal simulator passage to the master cylinder passage.

A vehicle includes at least one brake assembly configured to brake at least one wheel of the vehicle in response to an applied voltage. A power supply is in signal communication with the at least one brake assembly. The power supply is configured to operate in a first mode that outputs a first voltage and a second mode that outputs a second voltage greater than the first voltage. A brake control system is in signal communication with the at least one brake assembly and the power supply. The brake control system is configured to determine a driving state of the vehicle, and is configured to output a brake boost request signal to initiate the second mode of the power supply in response to detecting the driving state, wherein a braking response time of the at least one brake assembly is improved in response to applying the second voltage.

The actuating device for a vehicle brake system comprises a force input member, which can be coupled to a brake pedal, and a brake master cylinder. The brake master cylinder has at least one force transmission member. The force transmission member is coupled to the force input member in an articulating fashion. The force transmission member is positioned to transmit a force, which has been exerted onto the force input member, to the brake master cylinder. The actuating device has at least one elastically deformable positioning element. The at least one positioning element produces a holding force with which the at least one positioning element holds the at least one force input member in an installation position relative to the brake master cylinder.

A quick replace axle for use on the non-drive axles of a vehicle comprising an outer sleeve and an inner axle wherein the inner axle fits into the outer sleeve and is held in place with a plurality of secure pins. The quick replace axle may also be hydraulic and may include a disk break assembly or a drum break assembly.
