Abstract
The present invention is directed towards a disk braking system for a bicycle having a rear disk coupled to a rear wheel. A rear brake caliper is coupled to a rear brake lever and the rear brake caliper is also coupled to a hydraulic actuator which has a piston that slides within a cylinder filled with hydraulic fluid and hydraulic tubing coupled to the cylinder and a front brake. When the rear wheel and rear disk are rotating, the rear brake caliper can be actuated which causes compresses rear brake caliper against the rear disk to slow the rotation of the rear wheel. The movement of the rear brake caliper can actuate the hydraulic actuator which causes hydraulic fluid to flow through the hydraulic tubing to actuate a front brake.
Claims10
A rear hydraulic braking system for a bicycle, the rear hydraulic braking system comprising:
- a rear brake assembly comprising a first brake pad and a second brake pad disposed on opposite sides of a rear brake surface of a rear wheel, wherein the first brake pad and the second brake pad are configured to releasably engage the rear brake surface to slow a rotation of the rear wheel;
- a rear brake lever operatively configured to actuate the rear brake assembly;
- a hydraulic actuator comprising a cylinder and a piston rotatably coupled to the rear brake assembly, the cylinder configured to hold a hydraulic fluid, and the piston configured to slide within the cylinder to compress the hydraulic fluid;
- and
- a hydraulic tubing fluidically coupled to the cylinder, the hydraulic tubing configured to direct compressed hydraulic fluid from the cylinder to a front brake assembly to actuate the front brake assembly to slow a rotation of a front wheel;
- wherein the rear brake assembly, when actuated, is configured to move due to rotation of the rear brake surface to actuate the front brake assembly to slow the rotation of the front wheel.
