Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster.
Use the turkey baster to remove old brake fluid from the master cylinder reservoir.
Clean the reservoir with a lint-free cloth.
Refill the reservoir with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).

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 press the brake pedal to build pressure, then open the bleeder valve to release air and old fluid.
Repeat until clear fluid with no air bubbles flows out, then close the valve and repeat for all four wheels.
Monitor fluid levels in the master cylinder during the process to avoid running it dry.

4. Check and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, brake pads and rotors if needed.
Inspect brake pads for thickness; replace if worn down to the manufacturer's minimum specification.
Check rotors for warping or deep grooves; replace if damaged.
Reassemble the brake components and torque bolts to the specified values in the service manual.

5. Final Assembly and Test

Reinstall any components removed during the process.
Recheck fluid levels and top off if necessary.
Test the brake pedal feel and ensure it is firm.
