Brake Fluid

Brake Fluid is essential to your vehicle’s braking system and therefore your safety. Most Brake Fluids sold conform to the USA "Department of Transportation" standards, and hence are given the name “DOT”. With the exception of DOT 5, which are silicone based fluids, DOT fluids are made up of a poly-glycol base with added lubricants, a modifier-coupler to protect the seals and inhibitors to prevent corrosion and oxidisation.

DOT standards specify the minimum boiling temperatures for Brake Fluids and require brake fluid performance across a range of temperatures. RAVENOL Brake Fluids not only meet but exceed these standards, and our Brake Fluids are specially formulated for high temperature stability, excellent viscosity at low temperatures and neutral behaviour towards sealing materials.

Brake Fluid absorbs moisture from the environment over time and will eventually become corrosive to your braking system, so changing your Brake Fluid when recommended is important to prevent brake failure and maintain the boiling point at a safe level. If your brakes start to feel spongy and ineffective, moisture in the fluid may be the issue and it’s time to get them checked. It’s also not a good idea to mix brake fluids unless the new and old fluids both state they are miscible with each other. If in doubt, get the fluid completely drained and replaced with the new one. It’s always best to think safety when it comes to your brakes!
