Rear Drum Brake Hardware Kit by Dynamic Friction Company®. Often overlooked during a brake repair, the drum brake hardware can be stressed, fatigued, or corroded within 1-2 years, which leads to a reduction in spring tension, premature/uneven wear, and noise. To ensure optimum braking performance and total confidence, DFC Drum Brake Hardware kits are precisely designed with the same attention to form, fit, and function as Original Equipment Manufacturers.
