【摘要】:
Brake fluid: Normal brake fluid maintenance cycle is 2 years or 48,000 km.
Brake fluid: Normal brake fluid maintenance cycle is 2 years or 48,000 km. Regarding the recommended maintenance cycle for brake fluids, European manufacturers are generally set to several years; and Japanese and American car manufacturers generally have detailed descriptions in their owner's manuals. For brake systems with anti-lock ABS function, it is especially important to replenish the brake fluid in time. This is mainly due to the pollution of dust and moisture in the accumulator, which can lead to the failure of the expensive valve body and thus bury the safety hazard.
When the owner finds that the braking force is weak, the brake fluid humidity test paper can be used to assist in analyzing whether the cause of the malfunction is caused by the brake fluid defect. If the root cause of the fault is insufficient brake fluid, a sufficient amount of brake fluid must be replenished in time. Moisture and dust that are normally infiltrated from the brake fluid reservoir vent (or abnormally when the reservoir lid is open) shortens the brake fluid maintenance cycle. While maintaining the brake fluid, do not neglect the wheel brakes.
Brake pads, brake drums, rotating bodies and brake calipers: When driving the current trend of the main vehicle, the focus of attention is how to scientifically and effectively maintain the front wheel brake system that acts as a 2/3 brake task. Now, as various rear-drive vehicles, all-wheel-drive vehicles, trucks and SUVs are everywhere, the traditional concept of “re-emphasizing the light” has gradually changed.
A semi-metallic brake pad that gradually replaces the asbestos lining will result in severe wear on the entire surface of the rotating body. Inspection of wheel brake components or brake pads is a complex task, and it is not simply a matter of visually observing the amount of wear at the midpoint of the front wheel brake pads from both sides. In the actual operation, even if the opening distance of the brake caliper just allows you to see the brake pads on both sides, it does not mean that it can be handled smoothly and unimpeded. In addition, due to the popular application of the brake guard, the contact surface of the rotating body and the brake pad is multi-blocked and difficult to see. As for the rear wheel with disc brakes, it is even more hidden and difficult to see.
Normally, we only focus on checking the tightness of the brake fluid when there is a significant leak in the system. Its comprehensive system checks include traditional static inspections (ie, in-situ static look-up of leaks) and dynamic inspections (ie, checking seals during braking). In any case, when the vehicle brake system maintains a follow-up mileage of 48,000 km, a comprehensive professional maintenance of the vehicle's brake system is required.
Slight scratches on the brake rotor are not a problem. However, excessive wear of the rotating body due to uneven tightening force of the tightening nut and uneven thickness of the rotating rotating body may seriously affect the braking performance. In order to reduce the weight, many rotating bodies adopt unconventional structural dimensions, which makes it difficult to meet the basic requirements for machining and clamping of some machine tools. If you find that a rotating body has been machined, replace it with the size of the second rotating body on the same axle. In theory, only one rotating body can be replaced, but in order to achieve the best brake balance, it is recommended to replace both rotating bodies on the same axle at the same time. This recommendation also applies to the rear brake drum.
During the braking process, the automatic inspection of the key functions of the brake caliper can be completed by sensing the return movement of the brake caliper piston. If the caliper piston is not returning smoothly, please replace it with a new one; if you want to bleed or charge the brake fluid, please make sure the bleed valve can be opened normally; if the bleed valve is condensed, please replace it with new one.

If the asbestos lining has worn out 3.175mm, the safe driving range is already limited even under light load. In addition, if a medium-high load brake is required at this time, the debilitating braking force of the wear lining will surely reduce the safety of the driving.
Some rear-wheel braked rear-drive vehicles employ a cap-type rotating body that also acts as a parking brake drum. Many car owners often neglect to cancel the parking brake and directly drive the car. The rotating body and the brake shoe perform direct metal-metal friction, which will result in serious wear of the rotating body, brake pad and brake shoe.
