Bleeder screw for disc brake assembly

A disc brake assembly comprising:

• a rotor adapted to be connected to a vehicle wheel for rotation therewith;
• a caliper having a recess and an aperture communicating with said recess formed therein, said aperture including a non-threaded outer portion, a threaded intermediate portion, and an inner chamfered portion, said non-threaded outer portion including a counterbore portion defining an inner diameter;
• a piston slidably disposed in said recess;
• a pair of friction pads earned by said caliper and disposed on opposite sides of said rotor;
• actuation means for selectively moving said friction pads between a non-braking position, wherein said friction pads are spaced apart from said rotor, and a braking position, wherein said friction pads frictionally engage said rotor;
• and
• a bleeder screw threadably disposed in said aperture of said caliper, said bleeder screw including an inner chamfered end, an outer end, and a main body extending between said inner chamfered end and said outer end, a passageway being formed through said bleeder screw which is adapted to bleed air from the disc brake assembly when said inner chamfered end of said bleeder screw is moved from engagement with said inner chamfered portion of said aperture, said main body including a first section adjacent said inner end having an external thread along a portion thereof defining a first section outer diameter, a second section adjacent said first section having an annular recess formed therein defining a second section outer diameter, and a third section adjacent said second section including a cylindrically shaped section and a hexagonly shaped section, said cylindrically shaped section defining a third section outer diameter, wherein said first section outer diameter and said third section outer diameter are greater than said second section outer diameter, and said third section outer diameter is less than said inner diameter of said counterbore portion;
• and
• an elastomeric seal disposed in said annular recess of said second section of said main body, said elastomeric seal adapted to sealingly engage a portion of said non-threaded outer portion of said aperture when said bleeder screw is disposed in said aperture.
