What Causes a Pickup Truck's Brakes to Be Hard and Unable to Stop?
1 Answers
A pickup truck's brakes being hard and unable to stop might be due to a vacuum booster pump leaking or malfunctioning. Here is some knowledge about hard brakes: 1. Reasons for inability to stop: The vacuum booster pump only generates vacuum and provides assistance when the engine is running. When the engine is off, it no longer provides assistance, but there is still some residual vacuum. After the engine is turned off and the brakes are pressed, this vacuum completely disappears. 2. Solutions: Take the vehicle to a repair shop to check if the brake booster pump, pipelines, or master cylinder are leaking or malfunctioning, and repair them as needed.
