Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and is in "Park" or "Neutral" with the parking brake engaged.
Tools Required: Jack and jack stands, wrench set, brake fluid, OBD-II scanner, multimeter, torque wrench.

Inspect for any signs of contamination or debris in the fluid.

3. Check Brake Pads and Rotors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake calipers and pads.
Inspect the brake pads for thickness; replace if below the manufacturer's minimum specification.
Check the rotors for scoring or warping; replace if necessary.

4. Inspect Brake Lines

Examine all brake lines for signs of leaks or damage.
If leaks are found, replace the affected sections of the brake line.
Ensure all connections are secure and not corroded.
