HYDRAULIC BRAKE SYSTEM
First Claim
1. A hydraulic brake system for a vehicle, comprising:
- a cylinder; and
a piston movably arranged inside the cylinder,wherein the piston has a closed end, an open end and a piston wall surrounding a cavity of the piston between the closed end and the open end, the piston being movable along a longitudinal axis of the cylinder by hydraulic pressure within the cavity for pressing at least one brake pad against a brake disc,characterized in thatan outer diameter of the piston is smaller in a central section between the open end and the closed end than at the open end and at the closed end so that, in the central section, a space remains between the piston wall and an inner wall of the cylinder.

Abstract
The invention relates to a hydraulic brake system for a vehicle, comprising a cylinder (3) and a piston (4) movably arranged inside the cylinder (3), wherein the piston (4) has a closed end, an open end (6) and a piston wall surrounding a cavity (8) of the piston (4) between the closed end and the open end (5), the piston (4) being movable along a longitudinal axis (5) of the cylinder (3) by hydraulic pressure within the cavity (8) for pressing at least one brake pad (9) against a brake disc (2). An outer diameter of the piston (4) is smaller in a central section (13) between the open end (6) and the closed end than at the open end (6) and at the closed end so that, in the central section (13), a space (14) remains between the piston wall and an inner wall of the cylinder (3).
