D1354 Brake Pads

The brake pads are also called brake pads. In the brake system of the car, the brake pads are the most critical safety parts, and all the brake effects are decisive for the brake pads.

Brake pads are generally composed of steel plates, bonded insulation layers and friction blocks. The steel plates are painted to prevent rust. The SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure quality.

Brake pad inspection method

1. Look at the thickness: The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner as the friction is constant during use. When the thickness of the brake pad is visually observed, only about 1/3 of the thickness (about 0.5 cm) is left. The owner must increase the frequency of self-tests and be ready to replace them at any time. There are some models that do not have the conditions for visual inspection due to the design of the wheel hub. It is necessary to disassemble the tires to complete. If it is the latter, wait until the warning light is on, the metal base of the brake pad and the brake disc are already in the state of iron grinding iron. At this time, the sharp iron cutting will be seen near the edge of the rim of the tire. Therefore, we recommend that you check the wear of the brake pads regularly to see if they can be used, not just the warning lights.

2. listening to the sound: If the brakes are accompanied by the "iron shovel" sound or squeaking (may also be the role of the brake pads in the beginning of the installation), the brake pads must be immediately replace.

3. by foot feeling: If you feel very difficult to step on, often need to step on the brakes to achieve the previous braking effect, or when the emergency brake will obviously feel the pedal position is low, it may be that the brake pads have basically lost Friction, this time must be replaced.

Brake pad replacement method

1. Loosen the handbrake and loosen the hub screw of the wheel that needs to be braked (note that it is loosened, do not completely unscrew it). Use a jack to top the car. Then remove the tire. Before moving the brakes, it is best to use a special brake cleaning fluid to spray on the brake system to prevent powder from entering the respiratory tract and affecting health.

2. Remove the brake caliper screws (for some cars, just unscrew one of them and then loosen the other)

3. Hang the brake caliper with a rope to avoid damage to the brake circuit. Then remove the old brake pads.

4. Use the c-clamp to push the brake piston back to the innermost. (Please note that before this step, lift the hood and unscrew the cover of the brake oil tank, because the liquid level of the brake fluid will rise as the top brake piston is lifted). Install the new brake pads.

5. Replace the brake caliper and tighten the caliper screw to the required torque. Replace the tire and tighten the hub screws slightly.

6. Lower the jack and tighten the hub screws thoroughly.

7. Because in the process of changing the brake pads, we put the brake piston to the inside, and it will be empty when we first start to brake. It will be fine after a few steps.
