Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir.
If low, refill with the appropriate type of brake fluid (DOT 3 or DOT 4, depending on the model year).
Reconnect the battery terminal after refilling.

3. Inspect Brake Lines

Tools Required: Wrench set
Visually inspect all brake lines for signs of leaks, corrosion, or physical damage.
Tighten any loose fittings and replace any damaged lines.

4. Examine Brake Pads and Rotors

Tools Required: Jack, jack stands, lug wrench, torque wrench
Raise the vehicle and remove the wheels.
Inspect brake pads for wear; replace if thickness is below the minimum specification (generally 3mm).
Check rotors for scoring or warping; replace if necessary.

5. Test and Bleed Master Cylinder

Tools Required: Brake bleeder kit, clear tubing
Locate the master cylinder and check for fluid leaks.
If the pedal remains soft, bleed the brake system starting from the farthest wheel from the master cylinder.
- Attach clear tubing to the bleeder screw, submerge the other end in a container with brake fluid.
- Have an assistant press the brake pedal while you open the bleeder screw, then close it before they release the pedal. Repeat until no air bubbles are present.

6. Inspect Brake Booster

Tools Required: None
Check for vacuum leaks around the brake booster.
Test the booster by pressing the brake pedal with the engine off; the pedal should feel firm. Start the engine; the pedal should drop slightly indicating proper functioning.
