Solution

1. Preparation

Gather tools: socket set, brake fluid, brake bleeder kit, and a container for old fluid.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Put on safety glasses and gloves.

2. Inspect and Repair Leaks

Sub-step 1: Check the master cylinder for fluid leaks. Replace the master cylinder if necessary.
Sub-step 2: Inspect all brake lines and hoses for any signs of corrosion or damage. Repair or replace as needed.
Sub-step 3: Examine brake calipers and wheel cylinders for leaks. If leaking, replace the damaged component.

3. Bleed the Brake System

Sub-step 1: Start with the brake farthest from the master cylinder (usually the right rear). Attach a brake bleeder kit to the bleeder valve.
Sub-step 2: Have an assistant press the brake pedal while you open the bleeder valve, allowing fluid and air to escape.
Sub-step 3: Close the bleeder valve before the brake pedal reaches the floor. Repeat until the fluid runs clear without bubbles.
Sub-step 4: Move to the next brake in this order: left rear, right front, and finally left front.
Sub-step 5: Refill the master cylinder reservoir as necessary during the bleeding process.

4. Inspect and Replace Brake Components

Sub-step 1: Remove the wheel to access brake components.
Sub-step 2: Inspect brake pads for wear; replace if they are below the minimum thickness.
Sub-step 3: Check the rotors for wear or scoring. Resurface or replace as needed.

5. Test and Reassemble

Sub-step 1: Reinstall the wheel and lower the vehicle.
Sub-step 2: Pump the brake pedal several times to ensure firm feel and proper engagement.
Sub-step 3: Conduct a test drive to verify brake performance.
