Installation and Maintenance Tips for Your New Brake Pads

Once you've made your decision, proper installation and maintenance are key to maximising the performance and lifespan of your new Hawk brake pads.

Professional Installation is Recommended

While some enthusiasts are comfortable performing brake jobs themselves, it's generally recommended to have new brake pads installed by a qualified mechanic. Brakes are a critical safety component, and incorrect installation can lead to dangerous malfunctions. Professionals have the right tools, experience, and knowledge to ensure everything is fitted correctly and safely.

Bed-In Procedure is Crucial

New brake pads, especially performance-oriented ones like Hawk's, require a proper 'bed-in' or 'break-in' procedure. This process carefully heats the pads and rotors to transfer a thin, even layer of friction material from the pad onto the rotor surface. This creates an optimal interface for braking performance and helps prevent issues like premature wear, noise, and vibration.

While specific instructions may vary slightly by compound, a general bed-in procedure involves a series of moderate and then harder stops from varying speeds, allowing the brakes to cool down between sets. Always follow Hawk Performance's specific bed-in instructions provided with your pads for the best results.

Regular Inspection and Maintenance

To ensure your Hawk pads continue to perform optimally, regular inspection is vital. Check your brake pads for wear every 10,000-15,000 miles, or more frequently if you engage in aggressive driving. Look for:

• Pad Thickness: Most pads have a wear indicator. If the friction material is thinner than 3mm, they need replacing.
• Uneven Wear: This could indicate issues with your callipers or other brake components.
• Cracks or Chips: Signs of material degradation.
• Rotor Condition: Check for deep grooves, warping, or discolouration.

Also, ensure your brake fluid is at the correct level and that your brake lines are free from leaks or damage.
