For Oil Disc Brake Handle Cam Modification Parts Bearing Turning Point Modification Servo Wave Turning Point Modification Solve the abnormal noise of the brake handle Two sets, one car, using eight precision miniature bearings, 1 set includes two CNC -shafts and two stainless steel bearing sleeves, to achieve a non-destructive and perfect replacement of the brake lever cam, to solve the problem of brake lever springback abnormal sound, Slow bounce, improve brake feel. Applicable to: MT500 ZEEM640, DEORE series MT501 M6000 M6100 series M666 M675 M7000 M7100 series M785 M8000 M8100 to xtr series and saint series, For 's servo wave technology is essentially a system that uses cams and guide rails to achieve variable brake lever ratios, which brings wide pad clearance, high force and delicate brake feel to the brakes, but its shortcomings are also obvious. Increased the cost and complexity of the brake lever, and in order to save costs, for used plastic bushings and solid metal cams at the key turning points of the servo wave. The precision is low and the friction is , and it is easy to absorb dust and cause the brake feel to decline. There are problems such as slow rebound and abnormal noise. So a set of cam modification parts was carefully designed and equipped with high-cost precision bearings to improve the above problems of for Colour:Silver Material:Stainless steel Package Contents: 2 * -shafts 2 * Bearing sleeve Only the above package content, other products are not included.
