Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Check Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Tools Required: Brake fluid, funnel.

3. Inspect and Repair Leaks

Sub-steps:
- Visually inspect brake lines, calipers, and wheel cylinders for leaks.
- If leaks are found, replace the damaged brake line or component.
Tools Required: Wrenches, replacement brake lines or seals.

4. Bleed the Brake System

Sub-steps:
- Start from the farthest wheel from the master cylinder (usually the right rear).
- Attach a clear tube to the bleeder valve and submerge it in a container with brake fluid.
- Have an assistant pump the brake pedal and hold it down. Open the bleeder valve to release air and fluid, then close it before the pedal is released. Repeat until no air bubbles are present.
- Move to the next wheel and repeat the process.
Tools Required: Brake bleeder kit, clear tubing, wrench.

5. Inspect and Replace Brake Pads or Rotors

Sub-steps:
- Remove the wheel and inspect the brake pads and rotors for wear.
- If pads are worn below the minimum thickness, replace them. If rotors are scored or warped, replace or resurface them as needed.
Tools Required: Socket set, brake pad spreader, rotor puller.

6. Test Brake Booster

Sub-steps:
- With the engine off, pump the brake pedal several times to deplete vacuum. Then, hold the pedal down and start the engine. The pedal should drop slightly if the booster is functioning properly.
- If it does not drop, inspect and replace the brake booster if necessary.
Tools Required: N/A (basic inspection).
