Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
If the brake fluid level is low, remove the reservoir cap, and use a funnel to add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, container for old fluid
Start at the wheel farthest from the master cylinder (usually the right rear).
1. Attach the bleeder kit to the brake bleeder valve.
2. Have an assistant press the brake pedal several times and hold it down.
3. Open the bleeder valve to release air and fluid, then close it before the assistant releases the pedal.
4. Repeat until no air bubbles are observed in the fluid.
5. Move to the next wheel and repeat the process (left rear, right front, left front).

4. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, jack stands
If any brake components (pads, rotors, master cylinder, calipers) show signs of wear or damage:
1. Remove the wheel.
2. Unbolt and remove the caliper from the rotor.
3. Inspect brake pads and rotors; replace them if they are worn beyond specifications.
4. Replace any defective calipers or master cylinder as needed, following the manufacturer's torque specifications.

5. Final Assembly and Testing

Reassemble all components and ensure all bolts are torqued to specifications.
Refill the brake fluid reservoir to the recommended level.
Test the brake pedal feel before driving the vehicle.
