Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues.

2. Brake Fluid Inspection and Replacement

Tools Required: Brake fluid, funnel, shop towels
Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Check fluid level and condition; if dirty or low, replace it.
3. Use a funnel to add fresh brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) until the level reaches the full mark.
4. Reinstall the cap securely.

3. Brake Pad and Rotor Inspection

Tools Required: Jack, jack stands, socket set, torque wrench
Sub-steps:
1. Remove the wheel using a jack and socket set.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check rotors for scoring or excessive wear; measure rotor thickness and replace if below specifications.
4. If replacing pads, remove the caliper and support it without straining the brake line.
5. Replace the pads and reinstall the caliper.
6. Torque caliper bolts to manufacturer specifications (usually around 75 ft-lbs).

4. Brake Line Inspection and Repair

Tools Required: Wrench set, brake line flaring tool (if needed)
Sub-steps:
1. Inspect all brake lines for signs of corrosion or leaks.
2. If leaks are found, replace the affected brake line using the flaring tool for new connections.
3. Bleed the brake system to remove air using a helper or vacuum bleeder.

5. ABS System Check

Tools Required: OBD-II scanner
Sub-steps:
1. Connect the OBD-II scanner to check for any ABS-related codes.
2. If codes are present, refer to a repair manual for specific troubleshooting.
3. Clear codes after addressing any identified issues.
