Solution

1. Preparation

Tools Required: Socket set, wrench set, brake bleeder kit, OBD-II scanner, safety glasses, and gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and place wheel chocks behind the rear wheels for added safety.

2. Check and Replenish Brake Fluid

Locate the brake fluid reservoir.
If the fluid is low, top it off with the manufacturer's recommended brake fluid (DOT 4 for most Volvo models).
Inspect for leaks around the reservoir cap.

3. Inspect and Repair Leaks

Visually inspect all brake lines, fittings, and components for signs of leaks.
If any leaks are found, replace the damaged section of the brake line or component as necessary.
Tighten any loose fittings to eliminate leaks.

4. Bleed the Brake System

Attach the brake bleeder kit to the brake bleeder screw on one wheel cylinder.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process for each wheel, starting from the farthest wheel from the master cylinder to the closest (typically: right rear, left rear, right front, left front).
Monitor the brake fluid level in the reservoir and top off as necessary during bleeding.

5. Inspect and Replace Brake Components (if necessary)

Remove the wheel to access the brake components.
Check the brake pads for wear; if they are below the specified thickness, replace them.
Inspect the brake rotors for scoring or warping. Replace if necessary.
Reassemble the wheel and lower the vehicle.
