Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake pads for uneven wear; if worn unevenly, proceed to replace them.
4. Remove the caliper bolts using the socket set and slide the caliper off the rotor.
5. Remove the old brake pads from the caliper bracket.
6. Clean the caliper bracket and install new brake pads, ensuring they are oriented correctly.
7. Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications (typically 25-35 Nm).

3. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if stuck), torque wrench.
Sub-steps:
1. If the rotors are warped or damaged, remove them by unscrewing the retaining screws (if applicable).
2. Clean the hub surface and install new rotors, ensuring they are seated properly.
3. Torque the rotor retaining screws to manufacturer specifications.

4. Brake Fluid Check and Replacement

Tools Required: Brake fluid, funnel, bleeding kit.
Sub-steps:
1. Check the brake fluid level; if low or contaminated, flush the system.
2. Use a bleeding kit to remove old brake fluid from the system.
3. Refill with the appropriate type of brake fluid (DOT 4 recommended for most Volvos).
4. Bleed the brake lines starting from the farthest wheel to the nearest.
