Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Remove the master cylinder cap and inspect the brake fluid.
If the fluid is dirty or low, use a clean funnel to add new brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, container for old fluid.
Start at the wheel farthest from the master cylinder (usually the right rear wheel).
Attach the bleeder kit or tubing to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to allow fluid to escape until no air bubbles are visible, then close the valve and repeat for all four wheels in the correct order (right rear, left rear, right front, left front).
Ensure the master cylinder does not run dry during this process.

4. Inspect and Replace Brake Pads and Rotors (if necessary)

Tools Required: Jack and jack stands, socket set, torque wrench.
Remove the wheel to access the brake caliper.
Remove the caliper bolts with the socket set and carefully slide the caliper off the rotor.
Inspect brake pads for wear; replace if they are worn down to the wear indicators or less than the minimum thickness.
Check the rotors for scoring or warping; replace if necessary.
Install new pads and reassemble the caliper, ensuring to torque bolts to manufacturer specifications.
