  Cap Filler, brfc28

• Description:

  Genuine Ford brake master cylinder reservoir cap for the 2019-2023 Ford Ranger T6 mid-size pickup. This original-equipment cap seats onto the top of the brake master cylinder fluid reservoir and seals the DOT-specification brake fluid against moisture, dust, and airborne contamination while its integral rubber diaphragm flexes to follow the fluid level as the front and rear disc brake pads wear down. The Ford catalog name is Reservoir Cap and it belongs to the brake hydraulic group, not the engine group, so it should never be confused with an engine oil filler cap despite the visually similar shape. A buyer typically needs this part after the original cap has cracked, warped from underhood heat, lost or torn its rubber diaphragm, or been damaged during a brake fluid top-off, any of which lets humidity and debris reach the fluid, lowers the fluid boiling point, and can eventually cause a spongy pedal or moisture-driven internal corrosion of the hydraulic system. Fitting a fresh, correctly sealing cap restores a clean, closed reservoir and protects the fluid between services. This cap is dimensioned and vented for the Ranger master cylinder reservoir; a loose, mismatched, or missing cap allows contamination and can set a brake fluid warning. Keep the sealing surface and diaphragm clean and grease-free during installation and confirm the cap seats fully and squarely. As a genuine Ford component it matches the fit, materials, and function of the factory-installed cap on the 2019 through 2023 Ranger.

• Notes: Included with reservoir assembly.
