Brake Pads and Asbestos

Update time:2022-10-24

Over time, your vehicle's brake discs and pads wear out. If left unchecked, these two components can adversely affect your vehicle's parking ability. When they reach the end of their useful life, you must replace them. The main function of the brake pads is to absorb and dissipate heat from the brake caliper. These components also absorb dust.

wear indicator

Depending on the vehicle, the brake pads can have wear indicators to alert the driver when they need to be replaced. These indicators can be mechanical or electronic. The electronic version consists of a wear indicator in the brake pads and a circuit that triggers an alarm on the dashboard. When the wear limit of the brake pads is reached, the wear indicator contacts the warning contacts and activates the warning light. Depending on the vehicle model, two or four warning contacts may be installed. When replacing the brake pads, the electrical wear contacts must also be replaced.

Typically, a wear indicator assembly includes two parts: a first part that engages the caliper and a second part that screws into the first part. The first part is threaded to engage the second part, which can be secured around the ring retainer 63 . When the brake pad wears, the indicator pin engages the annular portion of the second member.

Material

There are two main types of brake pads: metallic and non-metallic. Non-metallic pads are made of synthetic compounds, while metallic pads are made of sintered steel. Metal brake pads are generally noisier, non-metal brake pads are gentler on the rotors. The downside of metal pads is that they wear out faster. They also require higher drive force to generate torque.

The original brake pad formulation was not optimal for performance. For this reason, brake pad manufacturers are constantly working on improving and optimizing their formulations. In this way, they can meet the needs of different users. For example, a race car may require harder materials than a normal car. Therefore, sintered friction materials are ideal for racing applications. It's also a good option for drivers who want to reduce the effects of brake fade.

life

There are many factors that affect the service life of brake pads. For example, if you drive very fast, hard or for a long time, your brake pads will wear out faster. If you drive carefully, you can store your brake pads longer. Plus, if you're driving on the highway, you'll be able to maintain longer brake pad life because you won't be slamming on the brakes. On the other hand, if you're driving around town, you'll have to stop more often and your brake pads will wear out faster.

Periodically check the service life of the brake pads. You can check this information by consulting the user manual. You can also use a brake pad gauge. This gauge will tell you how much friction material is left on the brake pads. This way, you will be able to determine how long your brakes will last. Additionally, many brake pads have audible indicators that can tell you when the pads are starting to wear out. These are usually spring clips that make a screeching sound when worn brake pads rub against the rotor.

asbestos

Asbestos is a dangerous substance that can cause many health problems. It has not been completely banned in the US and is still present in many products. A single dose of asbestos is harmless, but working in an environment where asbestos dust is common is a very serious health hazard. That's why it's important to avoid brake pads that contain asbestos.

The asbestos in brake products is mainly chrysotile, which is converted into forsterite during the braking process. However, unaltered chrysotile fibers are still present in high concentrations in brake dust cleaned by compressed air. This means that workers who have to install new brakes are at risk of significant exposure to this asbestos. Asbestos and asbestos-like fibers are thought to be the main cause of mesothelioma, the most common type of asbestos exposure.
