Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely elevated with jack stands if needed.
Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Ensure the cap is securely replaced after topping off.

3. Inspect Brake Components

Remove the wheel to access the brake assembly.
Inspect brake pads for thickness; replace if less than 3mm.
Check rotors for scoring or warping; replace if necessary.
Inspect calipers for leaks and ensure they are functioning smoothly.

4. Replace Worn Components

If brake pads are worn, remove the caliper (using a socket set) and replace pads with new ones.
If rotors are damaged, remove the caliper, then unbolt and replace the rotor with a new one.
Reassemble calipers and ensure all bolts are torqued to manufacturer specifications.

5. Test Brake Pedal and System

After repairs, pump the brake pedal several times until it feels firm.
Start the vehicle and check for any warning lights on the dashboard.
Test drive the vehicle at low speeds to ensure brakes engage properly.
