Disc brake repair means and method

A method for remounting a caliper assembly of a disk brake onto a supporting structure having a selectively sized threaded caliper bolt receiving aperture defined therein which has a stripped thread, the caliper assembly having mounting ears for floatable mounting on at least first and second axially aligned pin mounting surfaces having selected first and second diameters, respectively, the method comprising:

• providing a replacement bolt having a selectively configured threaded portion which defines a primary retention means, said bolt threaded portion being made of a material which is harder than the portion of the supporting structure wherein said bolt receiving aperture is defined, said bolt threaded portion having a diameter of at least 0.008 inches greater than said bolt receiving aperture to enable said threaded portion to cut a new thread having a depth of at least 0.004 inches in said bolt receiving aperture, said bolt threaded portion having a selectively defined channel defined therein to facilitate the thread cutting action of said threaded portion in said bolt receiving aperture, said replacement bolt further including a pin portion having a diameter equal to said first selected diameter;
• providing a bolt sleeve having an outside diameter equal to said second selected diameter, said sleeve having an inside diameter at least 0.008 inches greater than said bolt receiving aperture of the supporting structure;
• aligning the mounting ears of the caliper assembly with said bolt receiving aperture defined in said supporting structure;
• inserting said replacement bolt with said sleeve into the aligned ears and bolt receiving aperture such that said replacement bolt pin portion is positioned as said first pin mounting surface and said bolt sleeve is positioned as said second pin mounting surface of said caliper assembly and such that said bolt threaded portion is positioned for engaging said bolt receiving aperture of said support structure;
• and
• forcibly rotating said bolt to tappingly, threadingly engage said support structure such that said bolt threaded portion cuts a new thread in said bolt receiving aperture of at least 0.004 inches in depth thereby defining a primary bolt retention means.
