Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir (typically near the back of the engine bay).
2. Check the fluid level against the "MIN" and "MAX" markers.
3. If low, refill with the appropriate DOT fluid as specified in the owner's manual.
4. Reconnect the battery terminal.

3. Check for Leaks

Sub-steps:
1. Visually inspect all brake lines, hoses, and connections for any signs of fluid leakage.
2. If any leaks are found, replace the affected components (hoses, lines, or fittings).
3. After repairs, bleed the brake system to remove air pockets.

4. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access the brake caliper and rotor.
2. Inspect the brake pads for thickness; replace if worn down to 3mm or less.
3. Check the rotor for scoring or warping; replace if necessary.
4. Reassemble the wheel, ensuring all lug nuts are torqued to manufacturer specifications.

5. Brake Light Switch Check

Sub-steps:
1. Locate the brake light switch, usually mounted near the brake pedal.
2. Inspect the switch for proper operation; it should engage when the pedal is pressed.
3. If faulty, replace the brake light switch and test the lights.
