Honda Brake System Problem: Car Won’t Start

The Common Brake System Issues in Honda Cars

Honda cars are known for their reliability and performance, but like any other vehicle, they can experience problems over time. One of the common issues faced by Honda owners is related to the brake system, which can sometimes lead to the car not starting. In this article, we will discuss some of the brake system problems that can cause your Honda car to not start.

1. Brake Fluid Leakage

A common cause of a non-starting Honda car is brake fluid leakage. When the brake fluid leaks, it can affect the functioning of the brake system, leading to a loss of pressure and preventing the car from starting. It is important to regularly check the brake fluid levels and inspect for any signs of leakage. If you notice a decrease in brake fluid levels or any fluid puddles beneath the car, it is recommended to get it inspected and repaired by a professional mechanic.

2. Faulty Brake Light Switch

The brake light switch is responsible for detecting when the brake pedal is pressed, and it also triggers the brake lights to turn on. If the brake light switch is faulty or malfunctioning, it can disrupt the electrical system and prevent the car from starting. In some cases, the car may start but won’t shift out of park. If you notice any issues with your brake lights or difficulties shifting gears, it is important to have the brake light switch inspected and replaced if necessary.

3. Worn Brake Pads

Brake pads play a crucial role in stopping your vehicle. Over time, they wear out due to friction and need to be replaced. If the brake pads are excessively worn, it can cause the brake calipers to stick, leading to a car that won’t start. Additionally, worn brake pads can also damage other brake components, further exacerbating the issue. Regularly inspecting and replacing brake pads can help prevent this problem.

4. Damaged Brake Rotors

Brake rotors are essential for the proper functioning of the braking system. If the brake rotors become damaged or warped, it can lead to uneven braking, vibrations, and ultimately a car that won’t start. It is important to have your brake rotors inspected and resurfaced or replaced if necessary to maintain optimal braking performance and prevent starting issues.

5. Malfunctioning Brake Booster

The brake booster is responsible for increasing the force applied to the brake pedal. If the brake booster malfunctions, it can lead to a lack of braking power and cause the car to not start. Signs of a faulty brake booster include a spongy brake pedal, increased effort required to brake, and hissing noises when applying the brakes. A professional mechanic should inspect and replace the brake booster if needed.

6. ABS System Failure

The Anti-lock Braking System (ABS) is designed to prevent the wheels from locking up during braking. If the ABS system fails or malfunctions, it can affect the overall brake performance and potentially prevent the car from starting. Warning lights on the dashboard, unusual noises, and a pulsating brake pedal are indicators of ABS system issues. A qualified technician should diagnose and repair the ABS system to resolve the starting problem.

7. Electrical Issues

In some cases, electrical issues can be the cause of a Honda car not starting. The brake system is closely connected to the electrical system, and a problem with one can affect the other. Faulty wiring, blown fuses, or a malfunctioning brake light switch can disrupt the electrical flow and prevent the car from starting. A comprehensive inspection of the electrical system by a professional is necessary to identify and resolve any underlying issues.

8. Brake System Contamination

Contaminants, such as dirt, moisture, or debris, can find their way into the brake system and cause problems. These contaminants can lead to corrosion, rust, and blockages in crucial brake components, resulting in a car that won’t start. Regular maintenance, such as brake fluid flushes and inspections, can help prevent contamination-related issues and ensure the proper functioning of the brake system.

9. Brake Master Cylinder Failure

The brake master cylinder is responsible for generating hydraulic pressure and distributing it to the brake calipers. If the brake master cylinder fails, it can lead to a loss of brake fluid pressure and cause the car to not start. Symptoms of a failing brake master cylinder include a soft brake pedal, brake fluid leaks, and a decrease in braking performance. A professional mechanic should inspect and replace the master cylinder if necessary.

10. Faulty Brake Sensors

Modern Honda cars are equipped with various sensors that monitor and control the brake system. If any of these sensors are faulty or malfunctioning, it can disrupt the brake system’s operation and prevent the car from starting. Common brake sensors include the wheel speed sensors, brake fluid level sensor, and brake pad wear sensor. Diagnosing and replacing the faulty sensors should resolve the starting issue.


A problematic brake system can lead to a Honda car that won’t start. By being aware of the common brake system issues and regularly maintaining and inspecting your brakes, you can prevent these problems and ensure the reliable performance of your Honda vehicle. If you encounter any starting issues or suspect brake system problems, it is recommended to seek professional assistance to diagnose and resolve the underlying cause.
