This problem essentially occurs in power brakes. However, power brakes are not the only cause.

Before you decide what you should do about your engine not starting and the brakes being locked, you need to get to its cause. You need to figure out what is causing your brakes to be locked.

Here are common reasons why the push to start car won’t start and the brake is locked:

1. Exhausted Vacuum

Most cars nowadays have power brakes. The power assist that brakes have is dependent upon engine vacuum. The vacuum diaphragm in your power brakes helps you control your car’s brake pedals.

It means that the vacuum controls the force you apply on your brake pedal to optimize your brakes’ control.

When you switch off your car’s engine, a slight vacuum is stored in the system. This vacuum reserve runs out pretty quick.

When your engine is off, and the vacuum is gone, the next time you press your brakes, they will be locked, and you will not be able to press them quickly.

While your power assist using the vacuum would usually have helped you, in this case, it is not present and thus will not. It also means that your brakes will be fine once your car starts again.

However, if, at the same time, your car is not starting, you may want to explore why your car is not starting either. Here are some reasons why:

Fuel Delivery Issues

Your car is not starting because enough fuel is not being delivered into the combustion chamber. As a result, your engine will not start.

If on top of this, your brake pump is exhausted, it will lock your brakes as well. It often happens when the fuel pump has failed or is clogged, or the injectors fail.

Dead Battery

A relatively common reason your car won’t start could be that your battery is dead. If your car is completely unresponsive when you push to start it, it is likely because of a dead battery.

Depending on the age and condition of the battery, you may have to jump-start or even replace it.

2. Brake Drag

Brake drag is a condition in which the brake calipers may activate and lock even though you have not pressed on your brakes. It is due to residual hydraulic pressure.

It can result in locking up your brakes and could be why your car won’t push start.

Furthermore, brake drag may occur if your calipers are not appropriately aligned with your rotor.

It is a problem that needs to be resolved right away as It can cause mechanical failure of other braking system components.

3. Brake Lock-Up

Another scenario in which your brakes may lock up is when you break too hard. Even though you may have done this to avoid a crash, this could be harmful to your braking system.

When brakes are applied fully, they can activate the total stopping power.

When this spark is not created, neither is the fuel ignited. It explains why your car won’t start in this case.

5. Faulty Battery Terminal

Another cause that leads to the push to start the car not working and locking the brakes is the battery’s issue.

One issue is when the starter cable disconnects from the battery. Another cause is when there is corrosion in the battery terminals.

Similarly, another cause could be a dead starter motor. An indicator of this is loud clicking noises when you turn the key. A dead starter motor is characterized by a significant drop in voltage when you turn the key.

In such a situation, you need to do a thorough inspection of the battery and the surrounding and connected components. An inspection of all the components will help you determine what is wrong.

However, before you opt for a quick fix, you should find the root cause.

Problems with the ignition switch are found by pressing the brakes and checking to see the brake lights are still on. If it does not, the ignition switch might be the problem.

When you check the battery, you should look for corrosion underneath the terminals. Check to see if the battery needs to be replaced.
