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 for protection.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the cap from the brake fluid reservoir.
2. Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual).
3. If the fluid appears dirty or contaminated, proceed to replace it.

3. Bleed the Brake System

Sub-steps:
1. Connect a brake bleeder kit to the brake caliper furthest from the master cylinder.
2. Open the bleeder valve and pump the brake pedal until fluid flows out without bubbles.
3. Close the valve and repeat for each caliper in order (farthest to nearest).
4. Ensure the brake fluid reservoir does not run dry during the process.

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheels to gain access to the brake components.
2. Inspect brake pads and rotors for wear; replace if they are below minimum thickness.
3. Check brake calipers for proper operation and replace any that are seized or leaking.
4. Reassemble the brake system and wheels.

5. Test and Confirm Repairs

Sub-steps:
1. Start the vehicle and pump the brake pedal to ensure it feels firm.
2. Take the vehicle for a test drive to confirm proper brake function.
