A brake assembly has a lever configured to press a knee against a pushrod of a piston of a master cylinder assembly. The knee is configured to receive removable inserts that allow a user to modify the angle at which the lever activates the master cylinder assembly. The master cylinder assembly can include protrusions on the outer surface of the cylinder to protect the cylinder from impact damage.

A brake booster for a brake master cylinder of a motor vehicle, including a drive motor, which is connected/is connectable via a transmission to a pressure piston for the brake master cylinder, the transmission including a rotatable spindle nut having an inner thread, and a rotatably fixed axially displaceable spindle rod having an outer thread, the threads engaging with one another in order to convert a rotational movement of the drive motor into a translational movement of the spindle rod, and the spindle nut including an outer toothing, which is engaged with a toothing of a drive wheel of the transmission. It is provided that the spindle nut is displaceable axially relative to the drive wheel.

A modular non-linear spring system capable of simulating traditional brake pedal feel when incorporated into a hydraulic and/or electro-hydraulic vehicle braking system. The system can include a first spacer having a top surface and a bottom surface and an optional second spacer having a top surface and a bottom surface. In one arrangement, a first mechanical spring is in abutting engagement with the top surface of said first spacer, a second mechanical spring is in abutting engagement with the bottom surface of said first spacer and the top surface of said second spacer, and an optional third mechanical spring is in abutting engagement with the bottom surface of said second spacer. The springs are arranged to be progressively compressed using a brake pedal of the braking system.

To prevent occurrence of contamination at the time of press-inserting and fixing a guide ring that guides sliding of a piston.

In a brake hydraulic pressure control apparatus (1) including: a base body (2) having a cylinder hole (3); a piston (5) fitted to the cylinder hole (3) in a freely slidable manner; and a guide ring (8) attached to an opening (9) of the cylinder hole (3) and guiding sliding of the piston (5), the guide ring (8) has: a flange portion (8e) in a lower surface (8b) opposing the cylinder hole (3), the flange portion (8e) expanding in a radial direction of the guide ring (8); and bulged portions (8c) arranged at equally-spaced intervals to an outer circumferential surface (8d) of the guide ring (8) and each bulged outward in the radial direction of the guide ring (8) when compared to the flange portion (8e). When seen from a cross section in an axial direction (Ax) of the guide ring (8), each of the bulged portions (8c) has a tapered portion (8f) expanding in the radial direction of the guide ring (8) from the lower surface (8b) toward an upper surface (8a) of the guide ring (8).

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.
