About This Product
When you are rebuilding the rear brakes on a classic Ironhead, having the right internal components is critical for safety and performance. This rear brake caliper piston from MCS is a precision-made replacement designed specifically for 1979 to 1981 XL Sportster models. Over time, original pistons can become pitted or corroded, leading to sticking brakes or fluid leaks. This replacement piston restores the smooth operation of your rear caliper, ensuring consistent braking pressure. It replaces OEM numbers 44181-77A and 555445. It is a vital part for any mechanic looking to keep these vintage Sportsters stopping as they should on modern roads.
Manufacturer part number: 555445.
