What causes brake failure after a manual transmission car stalls?
2 Answers
After a manual transmission car stalls, you can restart it using normal methods. Below are some common starting techniques: Push-start: This is the most familiar and effective emergency starting method for the public, but it should not be used frequently as it may cause certain damage to the engine and clutch. Jump-start: If this situation occurs, it's best to seek assistance from others. If you have jumper cables in the car, you can use the battery jump-start method to start the vehicle. Tow-start: The principle of this method is similar to push-starting, but using another vehicle for towing is often more effortless and convenient.
I've seen this situation several times at the auto repair shop. If the brake becomes hard and difficult to press after a manual transmission car stalls, it's mainly because the engine has stopped. The brake's vacuum booster pump relies on the vacuum assistance generated by the engine's suction. Without the vacuum pressure difference, it naturally can't help. The brake pedal becomes extremely stiff, but don't think it's completely ineffective—the hydraulic system of the brake caliper is still functioning. You can still stop the car by stomping on the pedal with all your strength, though the effectiveness is greatly reduced. In this situation, stay calm, stomp hard on the brake, and quickly turn the key to restart the engine with your right hand. If your car often stalls at red lights, you should check for leaks or cracks in the vacuum hose. Aging rubber hoses are particularly common in cars that are seven or eight years old. Unstable engine idle could also be a cause, so it's a good idea to check for carbon buildup in the throttle body when you have time.
