1. A hydraulic braking system for a vehicle, the hydraulic braking system comprising:
a front brake assembly configured to slow rotation of a front wheel, wherein the front brake assembly is coupled to a front brake hydraulic tubing;
a rear brake assembly configured to slow rotation of a rear wheel, the rear brake assembly comprising a first brake pad and a second brake pad, the first brake pad disposed on a first side of a rear disc, and the second brake pad disposed on a second side of the rear disc opposite the first side;
a rear brake lever coupled to the rear brake assembly, wherein actuation of the rear brake lever causes actuation of the first and the second brake pads of the rear brake assembly to contact the rear disc to slow the rotation of the rear wheel and move the second brake pad forward relative to the first brake pad;
a hydraulic actuator comprising a cylinder configured to hold a hydraulic fluid and a piston configured to slide within the cylinder to compress the hydraulic fluid, wherein the second brake pad is coupled to the piston;
wherein the rear brake assembly is configured to actuate the first and the second brake pads to contact the rear disc to slow the rotation of the rear wheel while the rear wheel is in contact with a ground surface and move the second brake pad of the rear brake assembly forward relative to the first brake pad, causing the piston to move within the cylinder of the hydraulic actuator to compress the hydraulic fluid so that the hydraulic fluid moves through the front brake hydraulic tubing to actuate the front brake assembly to slow the rotation of the front wheel.
