Solution

1. Preparation

Gather tools and materials: socket set, brake fluid, brake line wrench, jack and jack stands, and a brake bleeder kit.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Refill Brake Fluid

Open the hood and locate the master cylinder.
Remove the cap and check the brake fluid level.
If low, top off with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Check for Leaks

Visually inspect brake lines, hoses, and connections for signs of fluid leakage.
If leaks are found, tighten connections or replace damaged lines as necessary.

4. Replace Worn Components

If brake pads are worn down, remove the wheel using a socket set.
Remove the caliper bolts, detach the caliper, and replace the brake pads.
Inspect rotors for wear; replace if necessary.
Reassemble caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.

5. Bleed Brake System

Use a brake bleeder kit to remove air from the brake lines.
Start with the wheel farthest from the master cylinder and work towards the closest.
Ensure the brake fluid reservoir does not run dry during the process.
