DFC Hardware Kits Often overlooked during a brake repair, the disc brake hardware can be stressed, fatigued, or corroded within 1-2 years, which lead to a reduction in spring tension, excessive caliper movement, premature/uneven wear, and noise. To ensure optimum braking performance and total confidence, DFC Disc Brake Hardware kits are precisely designed with the same attention to form, fit, and function as Original Equipment manufacturers. We’ve combined the features of PTFE Coating, Vulcanized rubber, and stainless steel all in one hardware kit.
