What is the reason why the Baojun 510 cannot brake effectively?

The reason why a car cannot brake effectively may be due to a malfunction in the vehicle's braking system components, which causes the braking system to fail. It could also be caused by excessive wear of the brake pads or brake discs, leading to an extended braking distance. Rust on car brake discs is a normal phenomenon. Below are detailed explanations about it: 1. Slight rust: Slight rust often occurs, such as after the car is exposed to rain overnight or when it remains wet after washing. In such cases, continuous braking while driving can help remove the rust, as the friction between the brake disc and brake caliper during braking will wear away the rust over multiple stops. 2. Severe rust: If the brake disc has severe rust, a thick layer of rust has formed on the entire surface of the brake disc. Stubborn rust can also accelerate the wear of brake pads, so it is necessary to take the car to a repair shop to have the brake discs polished.
Last month, my Baojun 510 also experienced soft brake issues, which turned out to be caused by excessive moisture content in the brake fluid. This is a common problem with older cars, especially in the humid climate of southern regions. When brake fluid absorbs moisture, its boiling point decreases, leading to bubble formation during hard braking, which makes the pedal feel soft. The mechanic also checked the brake pads and found that the original pads had accumulated a lot of dust over time, and the caliper guide pins were prone to rusting, causing poor retraction. The mechanic mentioned that a common issue with the rear drum brakes on this model is uneven wear on the brake shoes and suggested adjusting the brake clearance during the next maintenance. After switching to DOT 4 brake fluid and ceramic brake pads, I immediately noticed a significant improvement in braking power during hard stops.
