573726 Gasket, master cylinder rear

Keeping your braking system sealed is critical for both safety and performance on the road. This rear master cylinder gasket from MCS is designed specifically for 2014 to 2022 XL Sportster models. It provides a reliable, leak-proof seal to prevent fluid loss and ensure consistent hydraulic pressure when you hit the rear brake pedal. Over time, heat and exposure to brake fluid can cause the original gasket to perish or swell, so replacing it during a fluid flush or master cylinder service is a smart move. This part is sold individually and corresponds to part number 573726, making it a straightforward and necessary replacement for maintaining your late-model Sportster's braking system.
