Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.

2. Check and Refill Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir (usually near the back of the engine bay).
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, top off with the appropriate brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
4. Reattach the cap securely.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect all brake lines and hoses for cracks or frays.
2. Check around each wheel for any signs of brake fluid leakage.
3. If leaks are found, proceed to replace the affected line or component.
4. Clean any spilled brake fluid immediately to prevent damage to paint.

4. Bleed the Brake System

Sub-steps:
1. Gather a brake bleeder kit and an assistant.
2. Starting from the wheel farthest from the master cylinder (typically the right rear), loosen the bleeder screw using a wrench.
3. Instruct the assistant to pump the brake pedal several times and hold it down.
4. Open the bleeder screw to allow air and fluid to escape, then close it before the assistant releases the pedal.
5. Repeat for each wheel in the correct order (right rear, left rear, right front, left front) until no air bubbles appear in the fluid.

5. Replace Brake Components (if necessary)

Sub-steps:
1. If any brake components (pads, rotors, calipers) show wear, replace them.
2. For caliper replacement, remove the caliper bolts and slide the caliper off the rotor.
3. Install the new caliper and torque the bolts to manufacturer specifications.
4. Replace brake pads and rotors as per standard procedures.
