How to solve the problem of overheating brake pads?

Brake pad overheating is a problem often encountered in the use of vehicles, especially freight vehicles, the load is higher than ordinary vehicles, the required braking force also increases, so it is more likely to appear brake pad heat.

Since the source of braking force of the vehicle mainly relies on the friction of the brake assembly, it is inevitable that the temperature will rise during the use of brake pads, brake drums, etc., which is generally a normal phenomenon. However, once the temperature is too high, it is easy to cause a series of dangerous situations, such as brake failure, tire spontaneous combustion, etc., which seriously affects driving safety.

Causes of brake pads overheating

1, wheel end bearing lubrication is poor

Bearings lack grease, resulting in poor lubrication, light lead to shaft hair hot, abnormal wear, heavy cause vehicle spontaneous combustion or tire off.

Solution: In strict accordance with the requirements of regular inspection and maintenance of the wheel end.

2, brake pump return spring break or lose elasticity

In addition to lubrication maintenance, brake return is also closely related to the performance of the return spring in the brake pump.

Solution: Replace the brake pump return spring.

3. Lack of maintenance of braking system

Insufficient lubrication between brake components leads to rust, affects flexibility, poor return and brake drag.

Solution: Strengthen the inspection between the components to avoid poor lubrication.

4, brake air leakage, abnormal "automatic brake"

Brake air leakage can also lead to overheating of the brake.

Solution: Choose qualified auto parts and do daily inspection work.

5, the braking system debugging is not in place

The brake gap of the vehicle needs to be adjusted frequently, if the adjustment is unreasonable, it will also lead to abnormal friction, causing the brake pad to overheat.

Solution: Improve the monitoring of the temperature of the brake system after commissioning, and if there is overheating,

Consider whether debugging is reasonable.

6, brake brake drum out of round

The brake drum is also another cause of overheating.

Solution: Replace the qualified brake drum.

In addition to the above common reasons, the action of braking too frequently during driving will also cause brake pads to overheat, such as high frequency of sudden braking, long downhill continuous braking and so on.

How to deal with overheating brake pads

When it is found that the brake pads are overheating, do not pour cold water directly to cool down, so as not to crack the brake pads, brake drums, etc., the owner can slow down the speed, maintain predictive driving, use the engine brake, hydraulic retarding device instead of unnecessary brake operation, through the wheel end rotation of the air flow speed to cool the wheel end; If the section does not allow such operation, you can also find a safe area to stop as soon as possible, let the brake system cool naturally, and then go to the maintenance station as soon as possible to find the cause of overheating brake pads to solve.

How to prevent brake pads from overheating

In the daily use of the car, the car mainly does a good job of regular inspection of the vehicle, especially the configuration closely related to driving safety, timely maintenance, timely maintenance, once there is a problem to be repaired or replaced.

Add a wheel end cooling device to the vehicle, such as a sprinkler device, etc., if the area is not allowed to use, you can also choose to add a hydraulic retarder, usually pay attention to speed not too fast, so as to avoid frequent sudden braking, encounter a long downhill to use auxiliary braking devices, such as engine braking, exhaust braking, etc., to minimize the frequency of braking, to avoid overheating of the brake pads.

It is also important to choose a trailer axle of good quality. DARO Heavy Industry Group was founded in 2001, focusing on the development and manufacturing of trailer axles and accessories, the main products cover disc trailer axles, drum trailer axles, low flat trailer axles, three-line six-axis trailer axles, light trailer axles and air suspension, electromagnetic axles, etc., with advanced technology and reliable quality, Our customers cover more than 50 countries and regions in Asia, Europe, Latin America, Middle East, Australia, Africa, etc., and we have won the trust of domestic and foreign customers.
