How to Simply Deal with Brake Lock-up?
1 Answers
Brake lock-up can be handled simply as follows: 1. First, unplug the ABS spiral wire to check if the vehicle can start normally, thereby ruling out electrical issues. Ensure the tractor is in the air supply state, disconnect the hand control valve's air hose, and check if the air pressure at the outlet is normal (the air pressure should be high during the air supply state). 2. Check if the parking brake is in the released state. If the air circuit check reveals no issues, the final step should be to inspect the axle for mechanical faults. All braking states of the trailer's braking system are designed to maintain the free flow of the air supply line for safety. The tractor's foot brake and parking brake measures function by supplying air to the control lines. 3. If the front wheels lock up, the vehicle will basically move straight forward, maintaining a stable state, but it loses steering control. This means the driver cannot avoid obstacles or pedestrians during braking or perform necessary steering maneuvers on curves. If the rear wheels lock up, the vehicle's braking stability deteriorates. Even with minimal lateral interference, the vehicle may skid or even spin dangerously, especially on poor road conditions such as wet or icy surfaces, where wheel lock-up can severely compromise driving safety.
