4. DISC BRAKE , BRAKE ACTUATION AND METHOD FOR BRAKE
ADJUSTMENT
Disc brake
• A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a
"rotor"[1] to create friction.[2] This action slows the rotation of a shaft, such as a vehicle axle, either to
reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste
heat which must be dispersed.
• Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but
the principles of a disc brake are applicable to almost any rotating shaft. The components include the
disc, master cylinder, caliper (which contains cylinder and two brake pads) on both sides of the disc.

6. HISTORY OF DISC BRAKES
Development of disc brakes began in England in the 1890s. The first caliper-type automobile
disc brake was patented by Frederick William Lanchester in his Birmingham factory in 1902
and used successfully on Lanchester cars.
In 1921, the Douglas motorcycle company introduced a form of disc brake on the front wheel
of their overhead-valve sports models.
7. HALDEX DISC BRAKES
• The present invention is directed to a disc brake comprising a brake actuation mechanism and an
adjusting mechanism 11 which is adapted to reduce the distance between the brake pad 5 and the
brake disc during a brake application, Provides additional gap stretching to equal or greater values.
• The present invention also provides a method for adjusting the spacing between the brake pads 5 and
the brake discs in accordance with the circumstances in which the intervals must be increased during the
brake release movement.
10. VEHICLE TELEMATICS SYSTEM
• Generally, a telematics system refers to a system that combines telecommunications and
information processing. More specifically, the term has evolved to refer to automobile
systems that combine global positioning system (GPS).
• Communications between a vehicle and a remote assistance facility are important for many
reasons.
• One of Such reasons relates to the diagnosing of problems with the vehicle and forecasting
problems with the vehicle, called prognostics.
11. ABOUT VELETELEMATCICS HALDEX
• The present invention relates to methods and apparatus for diagnosing components in a vehicle and
transmitting data relating to the diagnosis of the components.
• vehicle and other information relating to the operating conditions of the vehicle, as well as the
geographical posi tion of the vehicle, to one or more remote locations distant
• from the vehicle, particularly via a telematics link.
