Solution

1. Preparation

Gather all necessary tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid any electrical issues.

2. Inspect Brake Components

Sub-steps:
- Remove the wheel using a lug wrench.
- Visually inspect brake pads for thickness; replace if less than 3mm.
- Check the brake rotors for scoring or warping; replace if necessary.
Tools Required: Lug wrench, caliper tool.

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- Remove the caliper bolts with a socket set and carefully lift the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- If replacing rotors, remove the rotor by unscrewing any retaining screws and sliding it off.
- Install new rotors and torque to the manufacturer’s specifications.
- Install new brake pads into the caliper bracket and compress the caliper piston using a caliper tool.
- Reattach the caliper and torque the bolts to the specified value.
Tools Required: Socket set, torque wrench, caliper tool.

4. Refill Brake Fluid

Sub-steps:
- Check the brake fluid level in the master cylinder and top off with the manufacturer-recommended brake fluid (DOT 4 for most Volvos).
- Ensure that the fluid is clean and free of contaminants.
Tools Required: Funnel, brake fluid.

5. Final Checks

Sub-steps:
- Reconnect the negative battery terminal.
- Press the brake pedal several times to ensure proper pedal feel and to seat the brake pads.
- Check for any leaks around the calipers and brake lines.
Safety Warnings: Ensure the vehicle is secure on jack stands if lifted.
