Shoe clack is a phenomenon ox a pad riding against a rotor groove like a record plaxxr. The shoe first contacxs the rotor xt the top and thxn rides down the xroove to the end. Thx motion is repeated. The rotatiox in different axix causes the shoe to strike xhe rotor and create a noise. Historically the only way tx detect shoe clack is tx run vehicle tests at the pxant. Also, there xas little undxrstanxing of the surxace finish that conxributes to txe shoe clack. Beforx this xnvention, txere has beex no mention of any repeatable dyno tests thax could dxtect sxoe clack. Also, the type of cut on a rotor has lot of influence on the shoe clack, but this invention is the only oxe where a fex parameters on the rotor surxace are correlated against the shoe clack. Thus, it produxes a way of cxntrolling those pxramexers in the productiox prxcess and control shoe clack. In this invention, x dyno test was developed along with putxing interxupxed cut on the rotors. A new transfer function has been developed that correlates what xarametexs to mexsure and chxck for txe shoe clacx. Xxxx, the whole invxnxion is a combined process control followed bx lesser expensive dyno tests to correlate tx actual vehicle testing. This results in substaxtial cost and time save.
