However ceramic brake pads are generally a term for a group of pads known as nao or non asbestos organic pads and ebc brakes was of course the pioneer of this technology back from its early roots 70 years ago when it was part of the bba group and manufactured products known as top dog in the uk. The high mechanical advantage of hydraulic and mechanical disc brakes allows a small lever input force at the handlebar to be converted into a large clamp force at the wheel. A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or rotor to create friction. Benefit carbonceramic discs meet the needs of those who want excellence without compromise for their vehicles. Ceramic disc brakes brake ceramics free 30day trial. The disc effective radius r e should be as large as possible, and the final design depends upon the pad surface area and aspect ratio step 2. The reason why ceramic pads replaced semimetallic on commercial vehicles was the noise. Brake repair the advantages and disadvantages of ceramic.
The reason is that the materials used for ceramic pads such as filler materials and resin vibrate at a frequency outside the range of human hearing. We cover the designing of the disk brake construction. Ceramic pads are much quieter than their semimetal counterparts. I do not know what are the different types of disc brakes available on the market. At the beginning of this century, several automotive manufactures, like porsche ag, daimler ag and audi ag, introduced the ceramic brake discs to their sedan cars 9. If brake disc are in solid body, the area of contact between disc and pads are more. Thermal analysis of brake disc international journal of.
Working of drum brakes drum brakes work on the same principle as the disc brakes. This is a backvented disc designed to minimise disc coning but the present work also includes an investigation of a conventional front vented disc similar in dimension to the backvented disc but with different detailed.

Structural analysis the static structural analysis of disc brake rotor for other materials such as grey cast iron and metal ceramic are carried out.
For a disc brake, having determined the maximum disc outer diameter and thus the outer radius r o, the inner radius r i of the rubbing path can be determined from the good practice rule of r o r i. Porsche has succeeded as the first car manufacturer in the world to develop ceramic brake discs with involute cooling ducts for an efficient cooling. This pdf seminar report and ppt on modern composite ceramic disc brakes explains the design, material and development of ceramic brakes and its advantages over the conventional iron disc. As conclusion, based on the research above, i am confidence to said that metal matrix composites is still the best for automobile disc brake in certain situation. These brakes were lightweight and a cost effective alternative to the carbon ceramic variations available recently but the only difference is they cannot operate at the same temperatures. The purpose of brake disk dimensioning and design is to confirm that a bike can be stopped safely under any possible driving conditions. Modern composite ceramic disc brakes seminar report ppt. Because theyre mostly ceramic, these brake parts dissipate heat well, which keeps performance. For now, though, they are available only on upscale sport and luxury models.
Brembo sgl carbon ceramic brakes, a joint venture between brembo and sgl group, is the worldwide benchmark in design, development and production of carbon ceramic brake. If the disc brake rotor becomes worn down to a thickness of 1. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.
