Mini DOT 4 Brake Fluid (12 fl oz) - Genuine Mini 81220146735

Product Information

Brake fluid is essentially hydraulic fluid which meets the standards set by the Society of Automotive Engineers (SAE) and the Department of Transportation (DOT). There are three main categories of brake fluid: DOT 3, DOT 4, and DOT 5. DOT 3 and 4 are polyglycol based while DOT 5 is synthetic brake fluid. Glycol based fluids are hygroscopic which is a benefit as the fluid absorbs any water which prevents water droplets from forming in the fluid. By absorbing the water, this in turn prevents water from collecting which could either boil, freeze or corrode components. Changing the brake fluid in your vehicle routinely will reduce the chances of boiling brake fluid which could lead to brake fade or loss of brake operation altogether.

• High moisture content causing low boiling point
• Dirty or tarnished color
• Boiling over of the brake system under extreme braking conditions

About Genuine Mini

The original parts used by Mini to build your car are available as replacement parts under the “Genuine Mini” brand. Manufactured under the direction of Mini, expect excellent quality and a premium price since these parts are exclusively available through the Mini Dealership network.

You may not realize this, but the parts that make up your Mini are not necessarily manufactured by Mini. No cause for concern, as Mini designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mini for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mini parts box and find an OEM branded part inside, simply with the addition of a Mini logo.
