Timely and useful information about brake disks

A typical large sedan weighing 1690 kg is traveling at 134 km/h down a highway and you must hamper quickly. Let’s say the average tyres can shift a overwork of 0.85 before tires lose traction. We'll slack away at 0.81 to escape skidding down the freeway. This car will run down in around 87 metre and beget approximately 1170 kilowatt of momentum doing so. This energy has to be bailed through the brake system as to stop the vehicle. When you pump this much energy into the disc rotors in mere moments it beget lots of warmth and the amount of mass or weight in the disc-type rotor is critical as to cope with current load.

A typical front disc rotor on a heavy saloon is approximately 300 millimetres in diameter and weighs approximately 9.5 kg. We will focalize on the face disc as it usually get 70% of the braking load. A disc rotor composed of to main elements, the mounting bell which fastens to the axle and the friction strip to which the passivation torque is applied via the brake caliper. The brake lining or circle in current disc-type rotor weighs around 6 kilograms. In the above mentioned brake application this 9.5 kg circle will increase in temperature by approximately 125 deg C in just before 5 seconds. When the same 300 mm circle weighed 8.5 kilograms with a friction strip of 5.5 kg then the Tc increase would be closer to 137 Celsius. 10% increase in temperature does not clang all this much although by mischance warmth transfer is not all that easy. In a 1 off brake application an extra 10% probably wouldn’t make a noticeable difference. Although what arises in accomplishment propulsive on or off the track is a set of braking applications at regular spaces. The time amid brake applications is rarely sufficient to permit the disc to recover to the optimal special Tc so you end up with an accumulation of Tc increase over a period of time.
