No matter what the brake system is,brakes(disk type)or brake shoes(drum type)will eventually complete the braking action.Therefore,check the thickness of the brake pads or brake shoes regularly.When it is found that its thickness is close to or less than the minimum thickness specified by the manufacturer,it should be replaced immediately.While inspecting the brake pads,check the wear of the brake discs or brake drums.If there is a dent on the contact surface,use a CD or drum to ensure that the contact area with the brake pads increases the braking force.
For cars braking on the oil line,check the fluid level of the brake fluid before leaving the car.If it is found that the oil level has dropped,check immediately whether there is a leak in the brake oil circuit.Brake fluids will fail due to the absorption of moisture from the air for a long time.The brake oil should be replaced regularly according to the manufacturer's regulations.It is best to change it once a year.
For the air brake system,pay attention to constantly drain water from the system and replace the dryer regularly.Water in the air system can corrode the pipe and affect the braking effect.In severe cases,it can even cause the brake system to malfunction.In addition,check the pump's working condition and the wear of the air pump belt.If problems are found,they must be promptly replaced.
