Abstract:
1. A caliper brake system operable on a rotor of a vehicle comprising a housing, a bore within said housing, a piston slidably positioned within said bore, a spring assembly biasing said piston in an actuated position to engage the rotor, a fluid chamber defined by said bore and said piston, an end plug having a cylindrical body and an annular projecting rim, said spring assembly abutting said cylindrical body, and said annular rim providing an axial stop for said piston, an axial slot in said bore adjacent said end plug, and a set screw extending through said cylindrical body of said end plug and projecting into said axial slot of said stepped bore to selectively lock said end plug against rotation, and a hydraulic fluid supply network adapted to provide pressurized fluid to said fluid chamber to selectively overcome the biasing force of said spring assembly and move said piston to an unactuated position to release the rotor, said bore including a threaded portion, and said annular projecting rim including a threaded portion to matingly engage said threaded portion of said bore to selectively position said cylindrical body of said end plug within said bore, thereby adjusting the force applied by said spring assembly on said piston.
