brake fluid level

Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.
Most brake fluids used today are glycol-ether based, but mineral oil (Citroën/Rolls-Royce liquide hydraulique minéral (LHM)) and silicone-based (DOT 5) fluids are also available.
The origins of modern braking systems date back to 1917, when Scotsman Malcolm Lockheed patented a hydraulic actuated braking system. Initially, vegetable oil was used as a working fluid. But it did not meet the most basic requirements, and in the process of evolution, special brake fluids were created, which consist of a base and a package of additives (thickeners, anti-corrosion additives, colorants).

    Brake Fluid

    If you look under the bonnet of the IM6 there is little to see other than the plastic cover and access for the windscreen fluid. So where and how do you check the brake fluid levels?
