Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
3. Ensure the cap is securely replaced after refilling.

3. Inspect Brake Lines and Components

Sub-steps:
1. Visually inspect all brake lines for signs of corrosion or damage.
2. Look for fluid leaks around the calipers, brake hoses, and wheel cylinders.
3. Tighten any loose fittings or connections to ensure no leaks.

4. Bleed the Brake System

Sub-steps:
1. Start at the farthest wheel from the master cylinder (usually the passenger rear).
2. Attach a clear hose to the bleeder valve on the brake caliper.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, then close it when the pedal is pressed down. Repeat until no air bubbles appear.
5. Move to the next wheel, following the sequence (passenger front, driver rear, driver front).

5. Replace Worn Components (If Necessary)

Sub-steps:
1. If brake pads, rotors, or lines are worn or damaged, remove the wheel.
2. Replace brake pads and rotors as necessary, ensuring to torque bolts to manufacturer specifications.
3. Reinstall the wheel and lower the vehicle.
