Solution

1. Preparation

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

2. Brake Fluid Inspection and Replacement

Tools Required: Brake fluid, turkey baster, clean rags.
Using a turkey baster, remove old brake fluid from the master cylinder reservoir.
Clean the reservoir and refill it with the correct type of brake fluid (refer to owner's manual for specifications).
Safety Warning: Brake fluid is corrosive; avoid contact with painted surfaces.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, fresh brake fluid.
Start at the wheel furthest from the master cylinder (usually the right rear).
Attach the brake bleeder kit to the bleeder valve on the caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid; close it before the assistant releases the pedal.
Repeat this process on each wheel in the following order: right rear, left rear, right front, left front.
Ensure the master cylinder reservoir remains topped off during the bleeding process.

4. Inspect and Replace Brake Components if Necessary

Tools Required: Socket set, torque wrench, jack stands.
If brake pads are worn beyond specifications, remove the wheels and replace the brake pads and/or rotors as necessary.
Follow manufacturer specifications for torque settings when reassembling components.
