Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4), brake fluid funnel.
Use the brake fluid funnel to add fresh brake fluid to the master cylinder reservoir if low.
If fluid is discolored or contaminated, proceed to flush the brake fluid.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing.
Attach the clear tubing to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process for all four wheels, starting from the wheel farthest from the master cylinder (usually the right rear), then left rear, right front, and finally left front.
Check the fluid level in the master cylinder after bleeding each caliper.

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, jack stands.
Remove the wheel to access the brake caliper.
Inspect the brake pads for wear; replace if they are below the recommended thickness.
Inspect the rotors for scoring or warping; replace if necessary.
Reassemble the brake components and torque all bolts to manufacturer specifications.

5. Final Checks

Recheck the brake fluid level in the master cylinder reservoir.
Test the brake pedal for firmness before taking the vehicle for a test drive.
