my Volvo XC90 brake pads wear out too quickly what could be the issue

Solution

1. Preparation

• Gather tools and parts required.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the negative battery terminal.

2. Remove Wheel

• Using a jack, lift the vehicle and secure it with jack stands.
• Remove the lug nuts with a socket set.
• Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

• Remove the caliper bolts using a socket set.
• Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid strain on the brake line.
• Inspect the brake pads for wear and replace if necessary.
  • If replacing, remove the old pads by sliding them out of the caliper bracket.
  • Install new pads in the same position as the old ones, ensuring they are seated properly.

4. Inspect and Resurface/Replace Rotors

• Check the rotors for warping or scoring. Use a micrometer to measure thickness.
• If the rotors are within spec, they can be resurfaced. If not, replace them.
• To replace, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

5. Reassemble Components

• Reinstall the caliper over the new pads and rotor.
• Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
• Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.

6. Final Checks

• Reconnect the battery terminal.
• Pump the brake pedal a few times to seat the pads against the rotors.
• Check brake fluid level and top off if necessary.
