How often should the brake pads be replaced? What is the replacement period?

It is important for qualified drivers to have a thorough understanding of the condition of their car while driving, particularly the braking system. One crucial component of the braking system is the brake pads. They not only impact the car's braking performance but are also relatively easy to inspect and maintain. However, many car owners often have concerns regarding when and how frequently brake pads should be replaced.

The first is its composition

A brake pad consists of four layers: a heat insulation layer, a friction material layer, an adhesive layer, and a back plate. When the brake cylinder is activated, the pad pushes the back plate and applies pressure on the brake disc through the friction material layer. Thus, the quality of the friction material layer is of utmost importance for efficient braking. Some friction materials are hard and offer a longer lifespan, but their braking effect is poor. In contrast, softer materials offer better braking performance but have a shorter lifespan. Therefore, the durability of the brake pads is heavily dependent on the quality of the friction material used.

Brake pad replacement cycle

The replacement cycle for car owners can often become a subject of dispute. This typically arises due to conflicting interests between the repair shop owners who seek to extend the replacement cycle and the car owners themselves who prefer a shorter replacement cycle. It's a situation most car owners have likely encountered when visiting a 4S shop for maintenance. The shop's staff usually evaluates only the car's mileage and recommends an immediate replacement.

When do you need to replace the brake pads?

It is crucial for car owners to regularly check the thickness of their brake pads. Once the pad wears down to 3 mm, it is time to replace them. To avoid any negligence, it is recommended to listen for an alarm sensor on the brake pads. If the pad is too thin, the sensor will activate and sound an alarm on the dashboard. In case of an alarm, it is important for the owner not to panic, but rather drive to the nearest 4S shop to replace the brake pads. Staying attentive to the thickness of the brake pads can save the driver from accidents caused by failed brakes.

In conclusion, it is important to consider driving habits as they can significantly impact fuel consumption and wear on brake pads. Braking frequently during driving, particularly in traffic jams, not only consumes fuel but also accelerates brake pad deterioration. It should be noted that certain car models require front brake pad replacements after covering approximately 28,000 kilometers. However, the ability to drive 35,000 kilometers in the same vehicle can be attributed to individual driving habits. Therefore, the question of driving habits is a nuanced and intricate one that deserves careful consideration.
