Car Brake Not Working When Engine Is Off: Causes and Solutions

Introduction

When your car’s engine is off, the power brake system that normally amplifies your braking force is disabled. This can make it much more difficult to stop your car, especially if you’re driving at high speeds or in an emergency situation.

There are a few possible causes for your car’s brakes not working when the engine is off. The most common cause is a problem with the vacuum brake booster. This device uses the vacuum created by the engine to amplify the force of your foot on the brake pedal. If the vacuum brake booster is damaged or has a leak, it will not be able to provide the necessary assistance to your brakes, and you will have to apply much more force to stop your car.

Other possible causes of your car’s brakes not working when the engine is off include:

A leak in the brake lines
A problem with the brake master cylinder
A problem with the brake calipers or wheel cylinders
