Product Description
The 1040521/A Rear Brake Hose is a factory-original replacement designed for Royal Enfield models equipped with a rear disc brake. Unlike standard rubber hoses that can expand under high heat—leading to a “spongy” brake feel—this genuine hose features reinforced internal braiding. This construction maintains constant diameter under pressure, providing a crisp and immediate response at the brake pedal.
As an OEM part, it features factory-crimped end fittings that provide a 100% leak-proof connection to the banjo bolts. The hose is specifically routed and sized to accommodate the swingarm’s movement, ensuring it doesn’t rub against the tire or chassis during suspension travel.
Key Features:
-
Reinforced Durability: Multi-layer construction prevents hose expansion and “brake fade” during heavy use.
-
Corrosion-Resistant Fittings: Features high-quality plated banjo connectors to withstand road grime and moisture.
-
OEM Precision: 100% original part (PN: 1040521/A) ensures exact length and correct mounting angle.
-
Safety First: Tested to handle extreme hydraulic pressures far exceeding normal braking conditions.
-
UV Protected: Outer casing is designed to resist cracking and degradation from sunlight and weather.
