What are the performance characteristics of brake fluid?
1 Answers
The performance of brake fluid lies in its ability to ensure vehicle braking safety and provide excellent corrosion resistance. Introduction to brake fluid: Brake fluid is a high-concentration liquid with strong water absorption capacity. After being used for a period of time, its water content gradually increases. Brake fluid should be replaced every 2 years or every 40,000 kilometers driven. Alternatively, professional instruments can be used to measure the water content of the brake fluid. If it exceeds 5%, it should be replaced as soon as possible, otherwise it may affect driving safety. Precautions for brake fluid replacement: During the brake fluid replacement process, if air enters the oil pipe, the brakes may feel softer after replacement, potentially causing delayed braking or even brake failure. The complete drainage method can be used to replace brake fluid: open the bleeder valve of the brake caliper, start the engine, and repeatedly press the brake pedal until no oil comes out of the bleeder valve, then tighten it. Add new fluid to the reservoir, repeatedly press the brake pedal until firmness is felt, then loosen the caliper bleeder valve to drain fluid. When the pedal lowers, quickly tighten the valve. Repeat this process twice until no air bubbles emerge from the discharged fluid. Always check the fluid level in the reservoir to ensure it doesn't drop below the minimum mark.
