Brake reservoirs and reservoir caps are essential parts of your vehicle's brake system, keeping your brake fluid clean and cool. You'll find the right replacements for your make and model in our wide range of quality brake reservoirs and caps.
The brake reservoir is a durable plastic tank designed to contain and protect your car's brake fluid reserves. The reservoir ensures a constant supply of brake fluid to the master brake cylinder, retaining just enough fluid to safely bring your vehicle to a stop in the event of a fluid leak. Brake reservoirs and airtight reservoir caps are used to keep your brake fluid clean, preventing water and dirt from contaminating your supply and affecting the reliability of your brakes. Depending on the make or model of your brake system, either the reservoir or its cap will have a capacity sensor to alert you when fluid levels become low. Over time, exposure to the elements and the heat of the engine can cause your reservoir crack and corrode, leaking fluid and contaminating your system.
