Spoon reservoir tank covers serve three purposes. One, they help keep the reservoir tank caps in place during racing and spirited driving, helping prevent spillage of vital fluids. Second, even if the caps are jarred the tank covers help contain the spill and minimize fluid loss. Third, the tank covers prevent dust and debris from accumulating on the tanks and potentially contaminating the brake fluid. Furthermore, they help prevent the brake fluid from absorbing moisture from the atmosphere, which otherwise leads to erosion of braking performance and components. Sold in pairs.
