Before cleaning, it is necessary for owners to check the brake pads (disc type) or brake shoes (drum type), and brake oil. Because they are a critical core part of the entire braking system, brake pads (disc type) or brake shoes (drum type) should be replaced immediately if they are found to be close to or less than the manufacturer's minimum thickness.
Check the brake pad at the same time, but also check the wear of the brake disc or brake drum, such as the contact surface dents should be timely disc or light drum to ensure that the contact area with the brake pad to improve the braking force. For the car of oil braking, check the liquid level of brake oil before driving. If it is found that the oil level drops, it is necessary to immediately check whether there is leakage in the brake oil circuit. Brake oil will fail over a long period of time because it absorbs moisture from the air.
