The Peugeot 308 GTi has been designed by Peugeot Sport to deliver an exhilarating driving experience. One essential part of any car, especially a performance car is the braking system. The 308 GTi has front and rear disc brakes to keep you safe, but like any system, they need brake fluid to function correctly. In this article we will explain the importance of brake fluid and when you need to change it.
What is Brake Fluid?
Brake fluid has historically been a generic term for any fluid used to run a braking system. A number of different fluids have been used, such as castor oil, mineral oil, silicon, alcohol and glycol ether. All of these fluids have a common characteristic in common; they have a boiling point of at least 140ºC, which is ideal for a braking system. When braking, heat builds rapidly as the kinetic energy is converted into heat due to friction. The brake fluid will not boil under normal operations, it should not cause corrosion, and it should not compress.
How Does a Braking System Work?
A modern braking system uses a hydraulic brake fluid to transfer energy from one point to another. In this case, the brake pedal is pressed, then brake fluid held in the master cylinder is sent in a line to the brake calipers. The hydraulic pressure squeezes the two halves of the brake caliper together, the brake pads clamp the brake discs, which are attached to each wheel. The force exerted on the brake discs will slot the wheel rotation rate, and eventually, the car will be brought to a stop.
When Should Brake Fluid be Changed?
Most car manufacturers recommend that the brake fluid in your car should be flushed, replaced and the system bled to remove air bubbles at least every two years. Over time, brake fluid can draw water into it via the rubber seals in the braking system. When water is added the boiling point of the braking fluid is lowered, and the hydraulic performance will gradually be reduced. An early indication of this would be less responsive feeling when pressure is applied to the brake pedal. This situation will only get worse over time, and it shouldn’t be ignored. If the brake fluid is still not changed the braking system will be far less effective, and eventually, it will not work correctly,
The Peugeot 308 GTi Braking System
The Peugeot 308 GTi has powerful braking technology to provide consistent braking performance even in demanding circumstances. The 380mm front brake discs are ventilated, and the rear discs are 269mm in diameter. They are mounted on aluminium hubs and pinched by four 41mm and 38mm diameter pistons. There is a fixed front caliper finished in a vibrant red that boldly displays the Peugeot Sport signature.
