Brake fluid is an essential part of the braking process – when you depress the brake pedal, the fluid multiplies that pressure and transfers it to the wheels. As brake fluid ages it can absorb water from its surroundings. If this happens, when the brake fluid gets hot during braking the dissolved water will turn to vapour, giving a soft pedal feel and not allowing full transfer of the braking power. It’s important that you change it at least every 2 years and make sure that you’re using a fluid with a high boiling point. Prestone DOT 4 Brake Fluid has been developed using engineered technology to excel in high temperatures so that you can be sure it will perform for you on the road every day, while also protecting against corrosion. Formulated to excel in extreme temperature applications with a dry boiling point exceeding 260°C and a wet boiling point exceeding 150°C Corrosion protection; Guaranteed for all braking systems including ABS, using discs or drums; Reduces the possibility of fluid vaporisation and eventual brake failure. It is easy to select Prestone DOT 4 Brake Fluid as it is guaranteed for all braking systems, and the high boiling point means you can worry less about vapour lock.
