Jiaozuo brake

Brake lining is generally composed of steel plate, adhesive insulation layer and friction block. Steel plate shall be coated to prevent rust. SMT-4 furnace temperature tracker is used to detect the temperature distribution during coating to ensure quality. The insulation layer is composed of non heat transfer materials, with the purpose of insulation. The friction block is composed of friction materials and adhesives, which are squeezed onto the brake disc or drum during braking to generate friction, thereby achieving the goal of vehicle deceleration and braking. Due to friction, the friction blocks will gradually wear out, and generally speaking, brake pads with lower costs will wear out faster.

1. Under normal usage conditions, check the brake shoes every month or kilometer. Not only should the remaining thickness be checked, but also the wear status of the shoes should be checked, whether the degree of wear on both sides is the same, whether the return is smooth, etc. Any abnormal situations must be dealt with immediately.

2. The brake shoe is generally composed of two parts: an iron lining plate and a friction material. It is important not to wait until the friction material is completely worn out before replacing the shoe. For example, the front brake shoes of Jetta have a new thickness of 14 millimeters, while the maximum thickness for replacement is 7 millimeters, including a thickness of over 3 millimeters of iron lining plate and nearly 4 millimeters of friction material. Some vehicles have a brake shoe alarm function, and once the wear limit is reached, the instrument panel will give an alarm to prompt for shoe replacement. The shoes that have reached the limit of use must be replaced. Even if they can still be used for a period of time, it will reduce the braking effect and affect the safety of driving.

3. When replacing, it is necessary to replace the brake pads provided by the original spare parts. Only in this way can the braking effect between the brake pads and the brake discs be good and the wear is minimal.

When replacing the shoes, special tools must be used to push the brake wheel cylinder back. Do not use other crowbars to forcefully press back, as this can easily cause the brake caliper guide screw to bend and cause the brake pads to jam.

5. After replacement, it is necessary to apply a few foot brakes to eliminate the gap between the shoe and brake disc, which may cause foot failure to brake and lead to accidents.

After replacing the brake shoes, it is necessary to run in for 200 kilometers to achieve optimal braking effect. The newly replaced shoes must be driven carefully

Is the braking system ultimately made of brake pads (brake discs) or brake shoes (drum type)? Regularly check the thickness of the brake pads or brake shoes. When the thickness of the manufacturer is close to or less than the small thickness specified by the manufacturer, it should be replaced immediately. While checking the brake pads, it is also necessary to check the wear of the brake disc and drum, such as dents on the contact surface, timely brake disc or drum lights, to ensure the contact area with the brake disc and braking force.

Check the brake oil on the car. Before checking the brakes, carefully wipe the dirt on the master cylinder to prevent it from falling into the storage tank. Remove the fasteners (usually pins) and cover. For cylinders that are not calibrated, maintain the top of the tank at 6 millimeters. If there is a scale, keep the liquid level higher than the scale.

If the oil level is found to be falling, immediately check if there is a leak in the brake oil circuit. If the brake fluid is dirty, release and flush the entire system, then fill the master cylinder with new fluid. Brake oil should not be reused. All brake fluid released from the system should be discarded.
