What are the causes of poor braking in air brake systems?

1 Answers

The causes of poor braking in air brake systems can be attributed to the following six factors: 1. Air leakage in the brake lines. 2. Excessive clearance between the intake valve and the core rod of the brake valve, affecting the air intake volume. 3. Excessive free travel of the brake pedal or insufficient air pressure in the brake chamber. 4. Insufficient brake air pressure due to poor performance of the air compressor, low pumping capacity, or no air or low pressure in the air reservoir. 5. Poor contact between the brake shoe friction lining and the brake drum; the brake shoe friction lining is contaminated with oil or excessively worn. 6. Improper adjustment of the air brake control valve; improper adjustment of the two adjustment bolts for free travel and maximum working air pressure; the balancing spring is too soft (the brake valve opening is too small), the diaphragm is ruptured, or an unqualified rubber intake valve is used.

Why is there no response when playing music via Bluetooth in Audi?

If there is no response when playing music via Bluetooth, it might be due to the volume being too low. Simply increase the volume. Open the settings on your phone. In the settings, tap on 'Sounds & Haptics'. Another solution is to re-pair the devices. First, turn off the Bluetooth device, then press and hold the multifunction button to activate Bluetooth and re-pair it with your phone. When using Bluetooth, it's best to keep the devices close to each other. Then, restart your phone, clear the previous Bluetooth information, and search for the Bluetooth device again.

Is Wheel Alignment Necessary for Tire Wear?

Tire wear indicates that the wheel alignment data is incorrect, leading to the issue of uneven tire wear. It is recommended to replace the worn tires and then perform a wheel alignment. Below is relevant information: Adjusting Tire Pressure: If both shoulder edges of the tire are worn, the tire pressure is too low; if the center is worn, the tire pressure is also too low. Ensure timely inflation and avoid overloading. Performing Wheel Alignment: If the outer edge of the tire is worn, it may be due to excessive toe-in or camber angle, or a bent steering arm. If the inner edge is worn, it may be due to insufficient toe-in or camber angle, requiring wheel alignment correction.

Can a used car get a new license plate?

Used cars can get new license plates. Here are the extended details: 1. After selling the old car, the original owner can apply to retain and continue using the original license plate without participating in the lottery, directly applying for a renewal indicator. 2. Within six months of obtaining the renewal indicator, the original owner must submit an application to use the original license plate number when registering a newly purchased motor vehicle with the vehicle management office; otherwise, it will expire and become invalid. 3. To apply for license plate retention, three conditions must be met simultaneously. First, the vehicle owner must have owned the original vehicle for more than three years. Second, the application must be submitted within six months after completing the transfer or cancellation registration. Third, all traffic violations and accidents related to the original vehicle must be resolved.

What to Do When the Car Slips and Can't Climb the Slope?

Solutions for when the car slips and can't climb the slope: First, press the brake to stop the car and prevent it from rolling back, then start in first gear and choose a road surface with good traction, avoiding slippery surfaces such as water, snow, or loose sand. If this still doesn't work, safely reverse to the bottom of the slope. The car's climbing ability is determined by its traction being greater than the slope resistance and rolling resistance. Use the appropriate gear based on the slope's steepness to ensure the engine has sufficient power. If you feel the engine lacks power, quickly downshift. Once the RPM increases, maintain steady throttle. If the RPM continues to rise, upshift. If the slope is too steep to pass, consider unloading some weight to reduce the car's load.
