  • Track-Specific or Racing Pads: Some manufacturers produce pads specifically engineered for track use with compounds optimized for consistent friction at very high temperatures. These pads may not be ideal for street use due to noise or cold bite characteristics.

2. Driving Style and Track Conditions

Your choice should reflect how hard you push your XC90 on the track. For occasional track days or mild spirited driving, semi-metallic or high-performance ceramic pads may suffice. However, if you participate in endurance events or aggressive track sessions, consider racing-grade pads that can withstand sustained heat.

3. Compatibility and Fitment

Ensure that the brake pads you select are specifically designed for the 2018 Volvo XC90’s brake calipers and rotor dimensions. Using pads not optimized for your vehicle can lead to uneven wear, reduced braking performance, or even damage to brake components.

4. Balancing Street and Track Use

Many drivers use their XC90 for both daily driving and occasional track days. In this case, selecting pads that offer a good compromise between street comfort and track performance is essential. Some manufacturers offer dual-compound pads or street-legal track pads that provide strong braking without excessive noise or dust.

Several reputable brands manufacture performance brake pads compatible with the Volvo XC90. Some popular options include:

  • Hawk Performance: Known for their aggressive track compounds and proven performance in motorsports.

Before purchasing, verify the exact pad model suits the XC90’s caliper and your intended use.

Step-by-Step Guide to Installing New Brake Pads on Your XC90

Upgrading your brake pads is a task that can be handled by experienced DIY enthusiasts or performed by professional mechanics. Proper installation is crucial for safety and performance. Follow these detailed steps to ensure a successful upgrade:

1. Preparation and Safety

  • Park your XC90 on a level surface and engage the parking brake.
  • Loosen the lug nuts on the wheels where you’ll replace the pads.
  • Use a jack and jack stands to lift and securely support the vehicle.
  • Remove the wheels to access the brake calipers.

2. Removing the Old Brake Pads

  • Locate the brake caliper bolts and remove them carefully using the appropriate tools.
  • Gently lift the caliper off the rotor and support it using a bungee cord or wire to prevent stress on the brake hose.
  • Remove the old brake pads from the caliper bracket.
  • Inspect the rotors for wear or damage; consider replacing or resurfacing if necessary.

3. Preparing for New Pads

  • Clean the caliper, bracket, and rotor surfaces with brake cleaner to remove dust and debris.
  • Use a C-clamp or brake caliper piston tool to compress the caliper piston back into its bore, creating space for the new pads.
  • Apply a thin layer of high-temperature brake grease to the back of the new pads (the metal backing plates) and any contact points on the caliper bracket to reduce noise and ensure smooth operation.

4. Installing the New Brake Pads

  • Place the new brake pads into the caliper bracket, ensuring they are seated correctly.
  • Reinstall the caliper over the new pads and rotor.
  • Secure the caliper bolts to the manufacturer’s specified torque.
