Title: HYDRAULIC BICYCLE DISC BRAKE HAVING TWIN DISCRETE FLUID CIRCUITS TO OPPOSING CYLINDERS OF A CALIPER
Abstract:
A bicycle hydraulic disc brake having opposing caliper pistons riding in a pair of opposing caliper cylinders. Each caliper piston is configured to advance a brake pad operatively associated therewith into contact with a disc operatively received therebetween upon delivery of pressurized hydraulic fluid to the respective opposing caliper cylinder. A master cylinder is configured, upon actuation, to deliver pressurized hydraulic fluid to the caliper cylinders. An equalizer is provided in fluid communication with the caliper cylinders, the equalizer being configured to provide an equal volume of pressurized hydraulic fluid to each caliper cylinder upon actuation of the master cylinder.
