Tips for Choosing Brake Pad

Brake pads are a component of disc brakeused in automotive and other applications. Brake pads are steel backing plates with friction material bound to the surface that faces the disk brake rotor.

Brake Pads belong to braking system parts, which is very important for the car. If there is car accident, the driver applies the brakes to prevent from hitting something. So the brake cable must be sensitive and the brake pads must be strongly wear-resisting.

Every driver should know how to choose better brake pads for their cars and they must have some knowledge of the material of the brake pads.

Here are some tips for choosing brake pad:

Material of Brake Pad

Brake pad materials range from asbestos to organic or semi-metallic formulations. Each of these materials has proven to have advantages and disadvantages regarding environmental friendliness, wear, noise, and stopping capability. Semi-metallic pads provide strength and conduct heat away from rotors but also generate noise and are abrasive enough to increase rotor wear.

Ceramic compounds and copper fibers in place of the semi-metallic pad's steel fibers accommodate higher temperatures with less heat fade and generate less dust and wear on both the pads and rotors. They also provide much quieter operation due to the ceramic compound that helps dampen noise by shifting its resonant frequency beyond the human hearing range and reduced metal use (approximately 15% metal content by weight). Ceramic brake pads typically are suited for light-duty applications and not severe duty applications as encountered by medium duty trucks, etc.

Asbestos was widely used in pads for its heat resistance but, due to health risks, has been replaced with alternative materials, suchas mineral fibers, cellulose, aramid, PAN, chopped glass, steel, and copper fibers.
Depending on material properties, disc wear rates vary. The properties that determine material wear involve trade-offs between performance and longevity. Newer pads can be made of exotic materials like ceramics, aramid fibres, and other plastics. Vehicles have different braking requirements.
Friction materialsoffer application specific formulas and designs.
Brake pads with a higher coefficient of friction provide good braking with less brake pedal pressure requirement, but tend to lose efficiency at higher temperatures, increasing stopping distance.
Brake pads with a smaller and constant coefficient of friction don't lose efficiency at higher temperatures and are stable, but require higher brake pedal pressure.

Note: Nearly all cars these days have front disc brakes. Front brakes usually wear out more quickly than the rear brakes (which couldeither be disc or drum brakes), so they need to be changed more often.

You need to change brake pads when they get too thin, especially if they begin to make a persistent metallic squeaking or grinding noise when you press the brake pedal.

But noise alone isn't always the best indicator, so it's best to anticipate when this will happen by periodically inspecting the thickness of the brake pads.

If the front end of the car vibrates when you apply the brakes, your brake rotors may be warped. If the rotors appear grooved or uneven, they may be scored.
In either case the rotors may also need to be replaced or "turned" on a brake lathe, a procedure not covered here.

It is said that original auto parts cost too much money. Brake pads need to changed frequently.
This cost is absolutly high. However, there are many manufacturers produce the high quality brake

pads which can be fixed on different car models. Why not have a try to save money?
