What Are the Effects of Insufficient Brake Fluid?
2 Answers
Brake fluid is a liquid that enhances the braking performance in a vehicle's transmission system. Insufficient brake fluid can lead to the car's inability to brake effectively. Below is a detailed introduction to the effects of insufficient brake fluid and the precautions for its use: Effects: Brake fluid transmits the driver's braking force to the vehicle's brakes. The quality of the brake fluid and whether it is used properly directly affect the vehicle's braking performance and driving safety. When the brake fluid is insufficient, it is crucial not to continue driving, as air can enter the brake lines or wheel cylinders. Since air is compressible, it can cause insufficient pressure in the wheel cylinders, leading to inadequate braking or brake failure. Precautions for Brake Fluid Use: If gasoline, diesel, or windshield washer fluid is mixed into the brake fluid, it can severely impair braking effectiveness, and the fluid should be replaced immediately. For vehicles that have traveled 40,000 kilometers under normal driving conditions or have used the same brake fluid for over two years, the brake fluid may deteriorate due to prolonged use, so timely replacement is necessary. Vehicles equipped with a brake fluid level warning device should have the warning light monitored regularly to ensure the sensor is functioning correctly. When the brake fluid is low, it should be replenished promptly. The stored brake fluid should always be maintained between the minimum and maximum capacity marks.
Insufficient brake fluid is truly dangerous – I’ve learned this through years of driving experience. Low fluid levels drastically reduce braking system performance, causing inadequate hydraulic pressure transmission. The brake pedal may feel spongy or even unresponsive, significantly increasing accident risks, such as failing to stop during emergency braking. Air can also enter the system, creating vapor lock and delayed response. Prolonged neglect accelerates wear on brake components, potentially damaging the master cylinder or calipers, with repairs often costing thousands. Once, I noticed rapid fluid depletion and discovered a leaking hose—timely refilling averted disaster. For safety, check fluid levels monthly after the engine cools (10 minutes post-operation). The reservoir should be between MAX and MIN marks; if below MIN, promptly top up with the same type. A full fluid replacement every two years is highly recommended.
