Generally, it is caused by air in the brake master cylinder, brake fluid or oil pipe, blockage in the brake master cylinder or oil pipe, or loss of pressure due to wear of the brake master cylinder plunger. If oil still does not come out after cleaning, it is best to replace it. The following are related introductions: 1. Working principle: The working principle of the disc brake system is to install a disc that rotates synchronously with the wheel on the hub, and install a caliper on the fork and frame, then clamp the disc through the brake pads inside the caliper to achieve the braking effect. 2. Maintenance measures: Regularly check the brake disc and brake oil pipe, and repair in time if the brake is found to be ineffective.

What is the wading depth of a stock Jeep Wrangler?

The wading depth of a Jeep Wrangler is 762mm. When driving through water, ensure the vehicle moves at a low speed and constantly check the water depth. For manual transmission models, use the first gear as much as possible, maintain steady throttle control for a smooth passage. Automatic transmission models should also try to engage the forced low gear or snow mode to increase vehicle torque and prevent tire slippage, avoiding any abrupt driving maneuvers and stalling midway. Below is relevant information: Wading Depth: Generally, sedans cannot match SUVs in wading depth. The wading depth of sedans typically does not exceed 20 cm, and some lower-designed models may not even exceed 15 cm. Correct Method for Wading: Ensure the vehicle moves at a low speed and constantly check the water depth. For manual transmission models, use the first gear as much as possible, maintain steady throttle control for a smooth passage. Automatic transmission models should also try to engage the forced low gear or snow mode to increase vehicle torque and prevent tire slippage, avoiding any abrupt driving maneuvers and stalling midway.

Where is the Yuchai engine number located?

The engine number on the Yuchai engine block is located below the oil pump, typically consisting of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be viewed through the following 4 ways: The vehicle's driving license prints the engine number, usually located on the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, where each engine can only use one engine number and each engine's number is unique.
