Why change Brake Fluid Cap?

Replace your brake fluid reservoir cap for improved pressure equalisation and stunning appearance.

x-zero Brake Fluid Cap will keep your brake mastercylinder at the perfect pressure equalization to ensure your high-performance brake system performs as it should.

Rapid pad wear, especially on big brake systems, can cause negative pressure in your master cylinder.

Our replacement Brake Fluid Cap has a better pressure equalisation system than the factory cap, ensuring zero pressure variance.

This billet replacement coolant cap is engineered to replace the plastic one.

x-zero's full replacement cap is not to be confused with cheaper covers that simply cover the plastic cap. We believe your car deserves more than that.

Each cap is 6061 aluminium

Polished, then gloss-anodised in stunning Midnight Black to stay beautiful for year after year
