why does my Volvo XC60 First Generation (2008-2017) brake pedal feel spongy

Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety glasses and gloves for protection.

2. Check Brake Fluid

• Remove the master cylinder cap and inspect the brake fluid level.
• If low, top off with the recommended brake fluid type (DOT 4 for most Volvos).

3. Bleed the Brake System

• Locate the brake bleeder valves on each brake caliper.
• Start with the wheel farthest from the master cylinder (usually the right rear).
  1. Attach a clear plastic hose to the bleeder valve.
  2. Place the other end into a container to catch fluid.
  3. Have an assistant pump the brake pedal several times and hold it down.
  4. Open the bleeder valve to release air; close the valve before the pedal is released.
  5. Repeat until no air bubbles appear in the fluid; check fluid level frequently.
• Continue to the left rear, right front, and finally left front calipers.

4. Inspect and Replace Components

• Check the condition of brake pads and rotors; replace if worn beyond specifications.
• If leaks were found, replace damaged brake lines or calipers as necessary.

5. Reassemble and Test

• Reattach the master cylinder cap securely.
• Test the brake pedal feel; it should feel firm and responsive.
• If issues persist, consider further inspection of the master cylinder.
