Your car brakes are one of the most critical safety systems on your vehicle. They are responsible for bringing your car to a safe and controlled stop, protecting you and others on the road. When something goes wrong with your brakes, it can be a terrifying experience. One common issue that can arise is uneven brake pad wear, where only one brake pad on a single axle is significantly worn down while the other remains relatively new. This can lead to a variety of problems, including reduced braking efficiency, pulling to one side when braking, and even complete brake failure in extreme cases. Understanding why only one brake pad might be worn is crucial for ensuring your safety and maintaining your vehicle’s proper function.

Understanding Brake Pad Wear
Brake pads are friction materials that press against the brake rotors (discs) to slow down or stop your vehicle. They are designed to wear down over time as they perform this crucial function. However, uneven wear can indicate a problem with your braking system.
Factors Contributing to Uneven Brake Pad Wear
Several factors can contribute to uneven brake pad wear, including:
- Misaligned Wheels: If your wheels are not properly aligned, the brake pads on one side of the vehicle may be subjected to more friction than the others, leading to faster wear.
- Sticking Calipers: Brake calipers are the components that press the brake pads against the rotors. If a caliper piston sticks, it can cause the brake pad on that side to wear down more quickly.
- Damaged Brake Rotors: Warped or grooved brake rotors can cause uneven pressure on the brake pads, resulting in uneven wear.
- Suspension Issues: Problems with your suspension system, such as worn-out ball joints or control arms, can affect wheel alignment and contribute to uneven brake pad wear.
- Driving Habits: Aggressive braking or frequent hard stops can put more stress on the brake pads and lead to uneven wear.
Diagnosing Uneven Brake Pad Wear
If you suspect that you have uneven brake pad wear, it is important to have your vehicle inspected by a qualified mechanic as soon as possible. They will be able to diagnose the underlying cause and recommend the appropriate repairs.
Signs of Uneven Brake Pad Wear
Here are some common signs that you may have uneven brake pad wear:
- Pulling to One Side When Braking: If your vehicle pulls to one side when you apply the brakes, it could be a sign that one brake pad is worn down more than the other.
- Squealing or Grinding Noises: Unusual noises coming from your brakes, such as squealing or grinding, can indicate that the brake pads are worn down or damaged.
- Vibration in the Brake Pedal: If you feel a vibration in the brake pedal when you apply the brakes, it could be a sign of warped brake rotors or uneven brake pad wear.
- Reduced Braking Efficiency: If your brakes feel spongy or you notice that it takes longer to stop your vehicle, it could be a sign of worn-out brake pads.
Inspection Process
A mechanic will typically inspect your brakes by visually examining the brake pads and rotors for signs of wear, damage, or corrosion. They may also use a brake caliper piston compression tool to check for sticking calipers. In some cases, they may need to remove the wheels to get a better look at the brakes.

Remedies for Uneven Brake Pad Wear
The remedy for uneven brake pad wear depends on the underlying cause.
Addressing Brake Pad Wear
If the brake pads are simply worn down, they will need to be replaced. This is a relatively straightforward repair that a mechanic can typically complete in a short amount of time.
Repairing Sticking Calipers
If a caliper piston is sticking, it may need to be replaced or repaired. A mechanic can clean and lubricate the caliper piston or replace the entire caliper assembly.
Resurfacing Brake Rotors
If the brake rotors are warped or grooved, they may need to be resurfaced. This involves using a specialized machine to remove the damaged surface of the rotor. In some cases, the rotors may be too damaged to be resurfaced and will need to be replaced.
Correcting Wheel Alignment
If wheel misalignment is contributing to uneven brake pad wear, the vehicle’s alignment will need to be adjusted. This involves making adjustments to the suspension components to ensure that the wheels are properly aligned.
Importance of Regular Brake Maintenance
Regular brake maintenance is essential for ensuring your safety and the proper functioning of your vehicle. Here are some key reasons why: (See Also: How to Install Brake Shoe Springs? A Step by Step Guide)
- Prevent Brake Failure: Regular inspections and maintenance can help identify potential problems with your brakes before they become serious.
- Extend Brake Lifespan: Properly maintained brakes will last longer and perform more efficiently.
- Improve Safety: Well-functioning brakes are crucial for safe driving, allowing you to stop your vehicle quickly and effectively.
- Reduce Wear and Tear on Other Components: Properly maintained brakes can help reduce wear and tear on other parts of your vehicle, such as the rotors and suspension system.
Recap
Uneven brake pad wear is a common issue that can occur for various reasons, including misaligned wheels, sticking calipers, damaged brake rotors, suspension problems, and driving habits. Recognizing the signs of uneven wear, such as pulling to one side when braking, squealing or grinding noises, reduced braking efficiency, and vibration in the brake pedal, is crucial for addressing the problem promptly.
Regular brake maintenance, including inspections and pad replacements, is essential for ensuring your safety and the longevity of your vehicle’s braking system. If you suspect uneven brake pad wear, it is important to have your vehicle inspected by a qualified mechanic to diagnose the underlying cause and recommend the appropriate repairs.
FAQs
What are the consequences of ignoring uneven brake pad wear?
Ignoring uneven brake pad wear can lead to serious consequences, including reduced braking efficiency, pulling to one side when braking, brake failure, and potential accidents. It is crucial to address the issue promptly to ensure your safety and the proper functioning of your vehicle.
How often should I have my brakes inspected?
It is recommended to have your brakes inspected at least once a year or every 12,000 miles, whichever comes first. However, if you notice any signs of brake problems, such as squealing, grinding, or pulling, have your brakes inspected immediately.
Can I drive with one worn brake pad?
It is not recommended to drive with one worn brake pad. While you may be able to drive for a short distance, it is unsafe and can lead to further damage to your brakes and other components. Have your brakes inspected and repaired as soon as possible. (See Also: Who Paints Brake Calipers? The Lowdown)
What is the average lifespan of brake pads?
The average lifespan of brake pads can vary depending on driving habits, vehicle type, and road conditions. However, most brake pads last between 30,000 and 70,000 miles.
What are the symptoms of a sticking caliper?
Symptoms of a sticking caliper include uneven brake pad wear, pulling to one side when braking, overheating of the brake system, and a grinding or scraping noise when braking.
