Understanding how to break in brake pads properly can make a significant difference in your vehicle’s braking performance and longevity. This guide will navigate you through the different types of brake pads, the importance of the coefficient of friction, and step-by-step instructions for breaking in ceramic brake pads. Additionally, we’ll discuss the necessity of maintaining cleanliness during a brake job and why AMSOIL’s Brake Parts Cleaner can be your best ally in this process.
Brake pads are integral components of the braking system, and not all are created equal. Choosing the right type depends on several factors, including vehicle type, driving habits, and conditions. Let’s dive into the types of brake pads available.
Types of Brake Pads
Organic Brake Pads
Organic brake pads are composed primarily of non-metallic fibers and materials like kevlar, carbon, and even glass. These pads are generally softer than their counterparts, offering a quieter ride.
Characteristics:
- Made from non-metallic materials
- Softer than other pads
- Produce less dust
Pros:
- Quieter operation
- Generally more affordable
- Less wear on rotors
Cons:
- Wear out more quickly
- Less effective at high temperatures
- Not suitable for heavy-duty or high-performance applications
Semi-Metallic Brake Pads
Semi-metallic brake pads incorporate a mixture of metallic and non-metallic materials, offering a balance between performance and durability.
Composition:
- Blend of metallic and non-metallic materials
- Commonly used in most vehicles
Performance Attributes:
- Good stopping power
- More durable than organic pads
- May produce more noise
Ceramic Brake Pads
Ceramic brake pads are known for their excellent performance and longevity. Made from a mixture of ceramic fibers and other materials, they provide superior heat dissipation.
Benefits:
- Excellent braking performance
- Long-lasting
- Produce less brake dust
Heat Dissipation Properties:
- Better heat management compared to organic and semi-metallic pads
- Reduce the risk of brake fade
Dust Color:
- Usually white or light-colored, less noticeable on rims
Coefficient of Friction
The coefficient of friction is a critical factor in brake performance. It represents the resistance encountered when one material moves over another.
Definition
The coefficient of friction measures the degree of friction between two surfaces. A high coefficient indicates more friction, which is necessary for effective braking.
Importance in Brake Performance
High friction between the brake pad and rotor ensures efficient stopping power, essential for safety.
Ice and Sandpaper Analogy
Consider the difference between ice and sandpaper. Sliding ice across a table is effortless, indicating low friction. Sandpaper, on the other hand, resists movement, exemplifying high friction. For optimal braking, you need the high friction of sandpaper rather than the smooth slide of ice.
Choosing the Right Brake Pad
When selecting brake pads, several factors come into play. It’s crucial to match the pad type to your vehicle, driving habits, and conditions.
Factors to Consider
- Vehicle Type: Different vehicles require specific brake pads.
- Driving Habits: Aggressive driving may necessitate high-performance pads.
- Driving Conditions: Frequent stop-and-go traffic versus long-distance highway driving.
Ceramic Brake Pad Break-In Procedure
Properly breaking in brake pads, especially ceramic ones, maximizes their efficiency and lifespan. This process ensures an even distribution of the pad material on the rotor surface.
Importance of Proper Break-In
A proper break-in procedure lays the foundation for optimal brake performance, reducing noise and ensuring smoother operation.

Brake Job Cleanliness
Maintaining cleanliness throughout a brake job is vital to ensure optimal performance and avoid contamination.
Importance of Cleanliness
Contaminants like grease can interfere with the braking process, leading to inefficiency and potential safety hazards.
Risks of Grease Contamination
If grease or other contaminants come into contact with the brake pads or rotors, it can compromise the break-in process and overall braking performance.

Brake Pad Wear and Maintenance
Signs of Wear
- Squealing or grinding noises
- Reduced braking performance
- Visible wear on the pads
Recommended Inspection Intervals
Regular inspections can preemptively catch wear issues, typically recommended during routine service checks or every 20,000 to 30,000 miles.
DIY vs. Professional Replacement
While some may prefer DIY replacements, professional services ensure proper fitting and optimal performance.
Environmental Considerations
Eco-Friendly Brake Pad Options
- Organic brake pads are often more environmentally friendly.
- Consider ceramics with low environmental impact.
Proper Disposal of Old Brake Pads
Dispose of old brake pads at designated recycling or disposal centers to minimize environmental harm.
Noise and Vibration Issues
Common Causes
- Improper pad installation
- Worn-out pads
- Contaminated braking surfaces
Troubleshooting Tips
- Ensure proper installation
- Keep braking surfaces clean
- Use high-quality pads
When to Seek Professional Help
Persistent issues warrant professional diagnosis and repair.
Brake Fluid Maintenance
Importance of Brake Fluid
Brake fluid is critical for the hydraulic braking system, ensuring efficient force transfer.
Recommended Change Intervals
Typically, brake fluid should be changed every two years or 30,000 miles, whichever comes first.
Signs of Contaminated Fluid
- Discolored fluid
- Reduced braking efficiency
Performance Brake Pads
High-Performance Options
Specifically designed for enhanced performance, ideal for sports and high-speed driving.
Racing Applications
Racing brake pads are crafted for extreme conditions, providing superior stopping power and heat resistance.
Street vs. Track Use
While race pads excel on the track, street pads offer a balanced performance suitable for everyday driving.
Brake Rotor Compatibility
Matching Brake Pads to Rotors
Ensure compatibility between pads and rotors for optimal performance.
Rotor Materials and Their Properties
Different materials offer various benefits; for example, cast iron rotors provide durability.
When to Replace Rotors
Rotors should be replaced if they show signs of extreme wear, warping, or damage.
Breaking in brake pads is an essential process that significantly improves braking efficiency and pad longevity. By following the proper break-in procedure, maintaining cleanliness with AMSOIL Brake Parts Cleaner, and understanding the different types of brake pads, you can ensure your vehicle’s braking system remains in top condition.
