Keeping the Friction Alive

Friction plays a very vital role in the car brake system. It antagonizes the actual stoppage of the moving vehicle. This critical process happens when one depresses his foot on the brake pedal and then transmits the force from the foot to the brakes through a fluid. But, since the actual brakes require a much greater force than one could apply with his leg, the car must also multiply the force of the foot. Next, the brakes will transmit the force to the tires using friction, while the tires transmit that force on the road through friction as well. To ensure friction, the keen driver must rely on his rotors to execute the job. But just as well, the keen driver must rely on the Saab Rotors.

Saab Rotors</a> are the flat disc-like plates that provide the friction surface in a disc brake. When hydraulic pressure is applied to the caliper, the brake pads are squeezed against both sides of the rotor producing friction and heat. Some rotors have cooling fins between both faces and are called "vented" rotors. The rotors should always be resurfaced when new pads are installed. If worn beyond safe limits, cracked or severely warped, the rotor must be replaced.

Sometimes, deep scores get worn into the Saab Rotors. This can happen if a worn-out brake pad is left on the car for too long. Brake rotors can also warp---lose their flatness. If this happens, the brakes may shudder or vibrate when you stop. Both of these problems can sometimes be fixed by refinishing (also called turning or machining) the rotors. Some material is removed from both sides of the rotors to restore the flat, smooth surface.

After learning of the importance of friction in the brake system, one should have also learned that its catalyst, the Saab Rotors, are of prime value to the car and safety of its occupants. Also, one should know by now that entrusting this task to high-quality Saab parts, his car is in good hands.
