Billet Brake Fluid Reservoir Master Cylinder Cap Cover for Mazda

Upgrade the look of the factory brake fluid reservoir tank cap with our CNC machined billet aluminum cover. Each cap is machined in the USA from a solid block of billet aluminum, engraved with the BMS logo, and anodized red, blue, or black for protection.

This cover will fit most Mazda vehicles equipped with the same brake fluid reservoir shown in the picture below. This is not a full cap replacement. The Billet Cap Cover affixes to the top of your factory cap.

🔧 Install: Peel high temp double sided tape. Press the cap on hard all the way down until it's a tight fit over the factory cap. No black from the factory cap should be showing. This cap uses pressure to stay on with extra reinforcement from the double-sided tape.
