What to Do When the Car Brake Pedal Won't Depress?
2 Answers
A faulty brake light bulb or brake light switch may be the cause. If the issue lies with the brake pedal or the brake booster system, then the brake pedal or brake booster pump will need to be replaced. Below is relevant information about the braking system: 1. Introduction: The braking system consists of a control system, hydraulic system, and booster system. 2. Working Principle: The principle of the braking system is to create significant friction, converting the vehicle's kinetic energy into thermal energy. As is well known, energy cannot be created or destroyed; it can only be transformed from one form to another or transferred from one object to another, with the total amount of energy remaining constant. During acceleration, a car converts chemical energy into thermal and kinetic energy, and when braking, the braking system converts the car's kinetic energy into thermal energy, which is then dissipated into the air.
When the brake pedal is hard to press, it's likely due to a problem with the vacuum booster or a brake fluid leak. I've encountered a similar situation before—quickly stabilize the steering wheel, avoid sudden turns, gently pull up the handbrake to slow down, then pull over and turn on the hazard lights. Never continue driving; it's too dangerous! Check if the vacuum hose of the booster is loose or cracked, as aging can cause air leaks. If you're inexperienced, call a tow truck immediately for repairs—don't try to save money here. Regular brake system maintenance, including changing brake fluid, keeps your car safer. Remember, brake issues are serious—never delay repairs, or the consequences could be dire.
