Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check fluid level; top off with manufacturer-recommended brake fluid if low.
3. If fluid is contaminated (dark or cloudy), proceed to flush the system.

3. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear brake).
2. Attach a clear plastic tube to the bleeder valve and submerge the other end in a container partially filled with brake fluid.
3. Using a wrench, turn the bleeder valve counterclockwise to release air and fluid while an assistant presses the brake pedal.
4. Close the bleeder valve when fluid runs clear and without bubbles.
5. Repeat for each wheel, moving closer to the master cylinder (right rear, left rear, right front, left front).

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads; replace if they are worn down to the indicators.
3. Inspect rotors for warping or scoring; machine or replace as necessary.
4. Check calipers for proper operation and ensure they slide freely.

5. Test the Brake Booster (if applicable)

Sub-steps:
1. With the engine off, press the brake pedal several times to deplete the vacuum.
2. Start the engine while holding the brake pedal down; the pedal should drop slightly as the booster activates.
3. If it does not drop, the brake booster may need replacement.
