Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Check Fluid Level: Open the master cylinder reservoir cap and check the brake fluid level.
Top Off Fluid: If low, add fresh brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect Fluid Condition: If the fluid appears dark or contaminated, proceed to replace it.

3. Bleed the Brake System

Locate Bleed Screws: Identify the bleed screws on each brake caliper.
Attach Hose: Connect a clear plastic hose to the bleed screw and place the other end in a container.
Pump Brake Pedal: Have an assistant pump the brake pedal several times and hold it down.
Open Bleed Screw: While the pedal is held down, open the bleed screw to release air and fluid. Close the screw before the pedal is released.
Repeat Process: Continue until no air bubbles appear in the fluid, then repeat on all four brakes.
Check Fluid Level: Ensure the master cylinder does not run dry during this process.

4. Inspect and Replace Brake Components

Check Brake Pads and Rotors: If worn, replace the brake pads and resurface or replace the rotors as necessary.
Inspect Brake Lines: Look for any damage or corrosion on the brake lines and replace if needed.

5. Test Brake Booster

Check Vacuum Supply: Ensure the vacuum line to the brake booster is intact and functioning.
Test Booster Function: With the engine off, pump the brake pedal until it feels hard. Start the engine; the pedal should drop slightly if the booster is working properly.
