Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Check Brake Fluid and Leaks

Tools Required: Brake fluid tester, flashlight
Inspect the brake fluid level in the master cylinder; top off with the manufacturer's recommended brake fluid type if low.
Visually inspect brake lines and components for any signs of fluid leakage. Clean any spilled fluid immediately.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clean rags
Locate the bleeder valves on each brake caliper or wheel cylinder.
Start with the brake furthest from the master cylinder (usually the rear passenger side).
Attach the brake bleeder kit to the bleeder valve, then loosen the valve while someone presses the brake pedal.
Allow fluid and air to escape until a steady stream of fluid appears, then tighten the valve.
Repeat for each wheel in order (rear passenger, rear driver, front passenger, front driver).
Check and top off brake fluid as necessary after bleeding.

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn below the manufacturer's specification.
Check the rotors for scoring or warping; replace if necessary.
Reassemble the wheel and torque to manufacturer specifications.

5. Test Brake Booster (if applicable)

Tools Required: Vacuum gauge
Check the brake booster by applying pressure to the brake pedal with the engine off; it should feel firm.
Start the engine while pressing the pedal; it should sink slightly. If it does not, the booster may be faulty.
