Choosing the right automotive brake pads.

Brake lining, often referred to as brake pads, are heat resistant materials that press up against the brake rotor or disc to create friction. When the brake pedal is applied they activate a system that places the friction material against a disc that slows the wheels of the vehicle. This lining must be capable of enduring high temperatures while remaining soft enough to absorb noise and dissipate heat. In a standard brake pad replacement the motorist is normally unaware of the types of brake lining available due to the fact that for many years there were not many choices available. The brake industry is witnessing rapid developments in brake lining styles and materials thus giving the motorist many choices for their driving style and budget.

Types of Brake Pads

Asbestos - one of the most significant changes in the last decade has been the use of asbestos in lining material. The asbestos brake pad or shoe resisted heat and noise well but created a dust that was deemed a hazardous material. Asbestos brake lining has been phased out of part stores and is no longer available.

Semi-metallic brake pads semi metallic brake pads have been used for many years and are the most common type in the industry. These pads contain steel wool or steel fibers. Steel provides strength and conducts heat away from rotors. This allows the rotors the ability to handle extreme temperatures. But steel is abrasive and does cause rotor wear. The biggest drawback concerning semi metallic pads is the noise factor. Metal rubbing against metal causes vibrations that tend to produce that annoying screech or squeal you may have experienced after a brake job.

Organic brake pads- Organic pads are composed of carbon based compounds with glass or synthetic fibers. These pads were originally produced to replace the asbestos based pads and are well matched for the average motorists driving habits. But organic pads do not resist heat as well as semi metallic pads nor will they last as long.

Ceramic pads One of the main differences between ceramic enhanced friction materials and semi-metallic brake lining is that ceramic pads contain no steel wool or fiber. Ceramic brake pads first appeared in the early 90's but did not become popular until original equipment manufactures began using them in new automobiles. After-market ceramic pads (available locally) are designed to replace OEM pads and to upgrade brake performance on vehicles that were not originally equipped with ceramic-based pads. Ceramic pads are designed to virtually eliminate noise and/or break squeal. The ingredients in ceramic pads also produce a light colored dust that is not as visible as the black dust produced by semi-metallic brake pads. The dust does not stick to wheels as easy like semi metallic brake dust. We all know that it is not an easy task to scrub the annoying black brake dust from the wheels. Ceramic pads are available for virtually every model and make of car and truck at local parts houses. They may cost a little more but are highly recommended for drivers who are hard on their brakes. Ceramic pads are designed to extend brake pad life so the extra cost will be worth it.

When it comes time for a brake job, be sure to ask the technician for some helpful advice on what types of brake pads will fit your particular driving habits as well as your budget. But always keep in mind that the brake system is the most important safety component so always use quality parts. Also chose a repair facility that employs ASE Certified Technicians. Happy Motoring
