How often should the brake fluid of the Baojun 510 be replaced?

The brake fluid of the Baojun 510 should be replaced every 30,000 kilometers. Brake fluid, also known as hydraulic brake fluid, is an essential part of the braking system. In the braking system, brake fluid acts as a force-transmitting medium. Since liquids are incompressible, the pressure output from the master cylinder is directly transmitted to the wheel cylinders through the brake fluid.

What are the adjustment methods for lighter hydraulic power steering?

Hydraulic power steering can be adjusted to become lighter through the following methods: 1. Replace the power steering fluid: The power steering fluid serves as the working medium for the hydraulic power steering system, transmitting force primarily through liquid pressure. If the power steering fluid becomes dirty, deteriorates, or leaks, it can affect the operation of the hydraulic power steering system. In such cases, replacing it with a higher-quality power steering fluid is recommended. 2. Adjust the power steering pump pressure: The pressure of the hydraulic power steering system can be adjusted. Locate the pressure adjustment device near the outlet of the power steering pump and reduce the pressure to make it lighter. 3. Power steering system repair: If there is poor contact in the internal circuits of the power steering system or other issues, it may increase the resistance of the steering wheel. In such cases, the power steering system should be inspected and repaired.

What are the pros and cons of short springs?

Short springs have the following advantages and disadvantages: 1. Advantages: The vehicle's ground clearance is reduced, resulting in a noticeable improvement in stability during high-speed driving. Additionally, short springs generally have a higher damping coefficient, which effectively suppresses body roll during cornering and lane changes, allowing for faster cornering speeds and increased driver confidence. 2. Disadvantages: After installing short springs, ground clearance decreases by 3-4 cm, leading to reduced off-road capability. Extra caution is required when entering underground parking or crossing speed bumps. The suspension becomes stiffer, reducing comfort, especially when driving over rough roads where the bumpy sensation is quite pronounced.
