Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent accidental electrical issues.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (usually near the driver's side near the back of the engine compartment).
Remove the cap and inspect the fluid level. If low, use the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Fill the reservoir to the proper level, ensuring no contaminants enter.

3. Inspect and Replace Brake Components

A. Brake Pads

Remove the wheel using a socket set.
Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
To replace, remove the caliper bolts, lift the caliper, and swap the old pads with new ones.

B. Brake Rotors

While the wheel is off, check for rotor thickness and any scoring.
If rotors are warped or below the minimum thickness, remove them by unscrewing the caliper bracket and the rotor retaining screws.
Install new rotors, ensuring they are clean and properly aligned.

4. Repair or Replace Brake Lines (if needed)

Inspect brake lines for any signs of leakage or damage.
If damaged, replace the affected brake line with a new one, ensuring all fittings are tight but not over-torqued.

5. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and check if the brake warning light is still illuminated.
Test drive the vehicle at low speeds to assess braking performance.
