Disk brake assembly tool

A disc brake assembly tool for use with a disc brake assembly having a caliper body, a piston, and a break pad, the caliper body having a piston cylinder and a side wall, the piston cylinder being spaced apart from the side wall of the caliper body to define a channel for positioning the break pad, the side wall having an opening therethrough into the channel, the piston being disposable within the piston cylinder of the caliper body, the piston body being extendable into the channel of the caliper body, said disc brake assembly tool comprising:

• a base having an elongate center portion, an arm portion, and a foot portion, said arm and foot portions each having a terminal end, said arm and foot portions being extended substantially perpendicular from said center portion, said arm portion being spaced apart from said foot portion;
• a mount member being coupled to said terminal end of said arm portion, said mount member having proximal and distal ends, and a mount bore being extended therethrough, said mount bore being generally parallel with said central portion, said mount bore having an elongate groove being extended along the length of said mount bore;
• a tubular sleeve having a threaded lumen, an outer surface, opposite proximal and distal ends, and proximal and distal portions, said lumen of said sleeve having a longitudinal axis being extended between said ends of said sleeve, said proximal and distal portions of said sleeve forming and abutment therebetween, said sleeve being inserted through said mount bore, said proximal end of said sleeve being extended towards said foot portion, said distal portion of said sleeve being extended from said mount bore of said mount member;
• outer surface of said proximal portion of said sleeve having an elongate ridge, said ridge of said proximal portion of said sleeve being disposed within said groove of said mount bore;
• said outer surface of said proximal portion of said sleeve having a pair of spaced apart holes, said holes of said proximal portion of said sleeve being positioned towards said arm portion of said base one of said holes of said proximal portion of said sleeve being located towards said proximal end of said sleeve, an other of said holes of said proximal portion of said sleeve being located towards said distal end of said sleeve;
• said proximal end of said sleeve having a radial flange being outwardly radially extended therefrom;
• a securing bore being extended through said arm portion from said central portion to said mount member, said securing bore opening into said mount bore of said mount member;
• an elongate securing pin being extended through said securing bore, said securing pin having opposite first and second ends, said first end of said securing pin being positioned towards said central portion, said first end of said securing pin having a knob being extending therefrom, said second end of said securing pin being extendable into said mount bore such that said second end of said securing pin is insertable into one of said holes of said proximal portion of said sleeve;
• first biasing assembly biasing said second end of said securing pin towards said mount bore of said mount member, said first biasing assembly being positioned towards said first end of said securing pin;
• said sleeve being positionable within said mount bore between an extended position and a retracted position, said second end of said securing pin being insertable within one of said holes of said proximal portion of said sleeve when said sleeve is in said extended position, said securing pin being insertable within the other hole of said proximal portion of said sleeve when said sleeve is in said retracted position;
• an elongate threaded rod having opposite proximal and distal ends, said threaded rod being threadingly extended through said threaded lumen of said sleeve, said distal end of said threaded rod extending from said distal end of said sleeve, said proximal end of said threaded rod extending from said proximal end of said sleeve, said threaded rod being extendable towards said foot portion;
• said proximal end of said threaded rod having a rectangular stub extending therefrom;
• a second biasing assembly biasing said sleeve away from said foot portion, said second biasing assembly having a second spring, a stop washer, and a snap ring;
• said stop washer of said second biasing assembly being disposed around said distal portion of said sleeve, said stop washer abutting said distal end of said mount member, said stop washer abutting said abutment of said sleeve when said sleeve is positioned in said retracted position;
• said outer surface of said distal portion of said sleeve having a radial groove;
• said snap ring of said second biasing assembly being disposed around said distal portion of said sleeve and positioned in said radial groove of said distal portion of said sleeve;
• said second spring of said second biasing assembly being disposed around said distal portion of said sleeve and interposed between said stop washer of said second biasing assembly and said snap ring of said second biasing assembly;
• said foot portion having proximal and distal surfaces, and a slot therethrough between said surfaces of said foot portion, said slot of said foot portion being extended from said terminal end of said foot portion towards said central portion;
• said threaded lumen of sleeve being aligned with said slot such that said longitudinal axis of said lumen of said sleeve extends through a portion of said slot of said foot portion, said proximal end of said threaded rod being extendable through said slot of said foot portion;
• and
• an piston adapter plate being generally rectangular and having a mounting hole interposed between a pair of guide pin holes, said piston adapter plate being mountable to said proximal end of said threaded rod such that said stub of said proximal end of said threaded rod is inserted into said mounting hole.
