Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid, funnel.
If the brake fluid is low, clean the reservoir cap and add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Safety Warning: Brake fluid is corrosive; avoid contact with painted surfaces.

3. Inspect Brake Lines and Hoses

Tools Required: Visual inspection tools (flashlight), wrench set.
Inspect all brake lines and hoses for any signs of leaks, cracks, or corrosion.
If any damaged components are found, replace them immediately.

4. Check Brake Booster

Tools Required: Vacuum gauge (optional).
With the engine off, pump the brake pedal several times to deplete any vacuum. Then, start the engine.
If the pedal drops significantly after starting, the brake booster is functioning correctly. If not, consider replacing it.

5. Replace Brake Pads or Rotors (if needed)

Tools Required: Jack and jack stands, socket set, brake caliper tool, torque wrench.
Remove the wheel and inspect the brake pads and rotors.
If worn, remove the caliper, replace the pads, and resurface or replace the rotors. Reassemble and torque to manufacturer specifications.
