Frequently Asked Questions
Does the Billet Technology brake fluid cap seal correctly to prevent fluid contamination?
Yes. The 3023 is machined to match OEM thread specs and cap diameter. It seals against the reservoir the same way the factory cap does.
Is this cap compatible with DOT 3 and DOT 4 brake fluid?
6061-T6 aluminum is resistant to DOT 3 and DOT 4 brake fluid vapor. The cap will not degrade or absorb brake fluid.
Will the billet brake fluid cap work on all trim levels?
All vehicle trims listed in the fitment table are compatible. The reservoir neck thread pitch is standardized across those model years.
Can I get a custom engraving on this cap?
Select variants include custom laser engraving options. Check the product page variants for engraved finish availability.
How do I remove the cap after installation?
The cap threads off counterclockwise by hand or with a rag for grip if the engine is warm. No tools are required.
Will this cap discolor from engine heat?
Anodized and satin finishes on 6061-T6 aluminum are stable at typical underhood brake-system temperatures and will not discolor under normal use.
Is the Billet Technology brake fluid cap made in the USA?
Yes. The 3023 is manufactured in Lake Worth, Florida from certified domestic aluminum stock.
Does this product require any adhesive or sealant?
No sealant or adhesive is needed. The cap threads directly onto the OEM reservoir neck with no additional materials required.
