Car brakes are hard to push? CAUSE OF HARD BRAKE PEDAL AND CHEAP EASY FIX.

In this video, we will discuss the potential causes of a hard brake pedal and how to fix it if you have a car with a hard brake pedal and, as a result, have limited stopping power. Modern automobiles employ vacuum-controlled brake boosters. You might experience a hard brake pedal if you have a vacuum leak. A bad vacuum pump is another frequent cause of a hard brake pedal. Vacuum pumps are now found in most cars. Additionally, inspect the directional check valves. In some cases, a faulty brake booster may be the cause of a hard brake pedal.

If you have a hard brake pedal and your brakes are weak because the brake pedal is hard, we will explain what could be causing it. This is a very common problem and usually indicates a vacuum leak somewhere in the engine. The foot brake uses the brake booster which is controlled by the vacuum from the engine and often a vacuum pump. Many new cars also have a vacuum pump. This way the pump can help create an extra vacuum in case of a leak. However, there are a few factors that can lead to harsh brake pedals which we share with you in this video.

Does your vehicle have a stiff brake pedal? We'll show you some tests and checks to determine if this is the cause of your hard brake pedaling.

Check valve test

The check valve on the brake booster maintains vacuum in the brake booster even when the engine is off. This is a safety feature in the rare event that the motor fails. Without the engine, you lose the source of the vacuum. The depression stored in the booster - thanks to the non-return valve - allows you to stop your vehicle in complete safety.

An easy way to test the operation of the check valve is to disconnect the hose from the brake booster. If you hear a hissing sound when you disconnect the hose, this is an indication that the check valve is working.

Check the brake booster

With the car off, press the brake pedal four or five times until you get a hard brake pedal. Continue to hold the brake pedal with moderate pressure and start the vehicle. The brake pedal should go down. If this brake pedal stays hard, there is a problem with the brake booster.
