OEM Replacement Brake Master Cylinder Cap

If you're looking for a simple way to clean up the look of your engine bay, the Wehrli 100215 Billet Brake Reservoir Cap is a sleek upgrade that adds a subtle but noticeable touch of quality. Unlike basic covers that just sit on top, this is a full replacement cap, CNC machined from solid billet aluminum for a perfect fit and long-lasting durability. Finished in a clear anodized coating, it resists corrosion and holds up to brake fluid exposure without losing its clean appearance over time. It also includes a brand-new diaphragm seal to ensure proper function and pressure control. Installation is quick and easy, no tools required, and it drops right into place on any 1999–2026 Silverado or Sierra 1500, 2500HD, or 3500HD. It’s compatible with all Duramax platforms, from LB7 to L5P.
