Solution

1. Preparation

Gather tools and parts required for brake service.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the master cylinder.
2. Check the brake fluid level; if low, top up with the manufacturer's recommended brake fluid (usually DOT 3 or DOT 4).
3. If the fluid is contaminated (dark or has debris), drain and replace the fluid.
Tools Required: Brake fluid, funnel.

3. Check for Leaks

Sub-steps:
1. Visually inspect all brake lines, the master cylinder, and the brake calipers for signs of leaks.
2. Tighten any loose connections, and replace any damaged lines or components as necessary.
Tools Required: Wrench set, replacement brake lines or fittings if needed.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Use a brake bleeder kit or have an assistant pump the brake pedal while you open the bleeder valve to release air.
3. Close the valve before the pedal is fully depressed to avoid drawing air back in.
4. Repeat for the remaining wheels in the following order: right rear, left rear, right front, left front.
5. Check fluid levels frequently and top up as necessary to avoid introducing air.
Tools Required: Brake bleeder kit, wrench for bleeder valves.

5. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear (replace if less than 3mm of material remains).
3. Check rotors for scoring or excessive wear; replace if necessary.
4. Reassemble components and ensure all bolts are tightened to manufacturer's torque specifications (usually around 75-90 ft-lbs for caliper bolts).
Tools Required: Socket set, torque wrench, brake pads, rotors (if replacement is needed).
