Q. What is ABS / Antilock System.
A ABS /Antilock systems electronically monitor the speed of the wheels and regulate the hydraulic pressure accordingly. The aim is to maximize braking power while preventing the wheels from locking and skidding.
Q. What is bleeding.
A. A method of purging air from a brake system's hydraulic lines and cylinders. Air is compressible and contaminates brake fluid. It is released via a "bleeder valve".
Q. What is brake fade.
A. Reduction (or complete loss) of braking performance, usually caused by too much heat in the system.
Q. What is a cross drilled disc.
A. Disc with friction surfaces which have been drilled with rows of holes to improve cooling, reduce weight and provide an escape route for dirt and gasses which can be wedged between the pads and disc. High-performance rotors can be both cross-drilled and slotted.
Q. What is a curved vane disc.
A. Ventilated rotor in which the cooling channels (or vanes) have been curved to increase their ability to pump out hot air and cool the disc. Curved vane rotors are more efficient than conventional ventilated rotors and, as a side benefit, tend to be stronger.
Q. What is glazing.
A. The process whereby a brake lining or disc rotor becomes smooth and glossy due to excess heat.
Q. What are heat spots.
A. Shiny dark areas on a rotor caused by extreme heat.
Q. What is minimum thickness.
A. The thickness at which a disc rotor must be discarded. Through wear and machining a disc rotor becomes thinner over time; as a result it becomes less able to dissipate heat and more prone to warping and other problems. The minimum thickness is usually determined by the vehicle manufacturer.
Q. What is a proportioning valve.
A. Hydraulic control designed to stop the rear wheels from locking up (rear wheels become "light" under heavy braking and therefore more likely to skid.
Q. What is pulling.
A. Tendency of a vehicle to pull to one side under braking.
Q. What is pulsing.
A. Uneven or stutter-like force transmitted through the brake pedal during braking, usually caused by problems with disc rotors or linings.
Q. What is a spongy pedal.
A. Pedal which feels spring-like, perhaps due to the presence of air in the hydraulic system..
Q. What is a ventilated rotor.
A. The disc rotor which has a series of fins (or cooling passages) between the two friction surfaces to aid in heat dissipation.
