What Causes My Car to Stop When I Brake?
There are several reasons why your car might stop when you hit the brakes, and it’s often a combination of factors rather than a single cause. Here are some of the most common reasons:
1. Brake Pads Worn Out or Damaged
Worn out or damaged brake pads can cause your car to stop suddenly when you hit the brakes. This is because the pads are no longer able to effectively transfer the force of the brake pedal to the brake rotor, which can cause the car to lose traction and come to a sudden stop.
| Signs of Worn Out Brake Pads | Causes |
|---|---|
| Squealing or grinding noise when braking | Worn out or damaged brake pads |
| Vibration when braking | Warped brake rotor or worn out brake pads |
| Spongy brake pedal | Air in the brake lines or worn out brake pads |
2. Air in the Brake Lines
Air in the brake lines can cause your car to stop suddenly when you hit the brakes. This is because air can prevent the brake fluid from flowing properly, which can cause the brakes to malfunction.
| Signs of Air in the Brake Lines | Causes |
|---|---|
| Spongy brake pedal | Air in the brake lines |
| Brake pedal feels soft or spongy | Air in the brake lines |
3. Warped Brake Rotor
A warped brake rotor can cause your car to stop suddenly when you hit the brakes. This is because the rotor is no longer able to rotate smoothly, which can cause the brakes to malfunction.
| Signs of a Warped Brake Rotor | Causes |
|---|---|
| Vibration when braking | Warped brake rotor |
| Brake pedal feels spongy or soft | Warped brake rotor |
4. Brake Fluid Leaks
Brake fluid leaks can cause your car to stop suddenly when you hit the brakes. This is because the brake fluid is no longer able to flow properly, which can cause the brakes to malfunction. (See Also: How Does a Brake Pedal Work? Inside The Technology)

There are several steps you can take to prevent your car from stopping when you brake:
1. Regular Brake Maintenance
Regular brake maintenance is essential to prevent your car from stopping when you brake. This includes checking the brake pads and rotors regularly, and replacing them as needed.

| Brake rotor resurfacing or replacement | Every 50,000 to 70,000 miles |
2. Check for Air in the Brake Lines
It’s essential to check for air in the brake lines regularly to prevent your car from stopping when you brake. You can do this by bleeding the brake system and checking for any signs of air in the lines.
| Signs of Air in the Brake Lines | Causes |
|---|---|
| Spongy brake pedal | Air in the brake lines |
| Brake pedal feels soft or spongy | Air in the brake lines |
