Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Brake Fluid Inspection and Replacement

Tools Required: Brake fluid, funnel, clean cloths
Sub-steps:
1. Remove the master cylinder cap and inspect the brake fluid level.
2. If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified).
3. If the fluid is dark or contaminated, perform a complete fluid flush.
4. To flush, open the bleeder valves on each brake caliper starting from the furthest from the master cylinder, and pump the brake pedal until clean fluid is observed.

3. Brake Pad and Rotor Replacement

Tools Required: Jack and jack stands, socket set, torque wrench
Sub-steps:
1. Lift the vehicle with a jack and secure with jack stands.
2. Remove the wheel to access the brake components.
3. Remove the caliper bolts and slide the caliper off the rotor. Use a C-clamp to compress the caliper piston if necessary.
4. Remove the old brake pads and inspect the rotors for scoring or excessive wear.
5. Replace the pads and, if necessary, the rotors. Ensure rotors are within manufacturer specifications.
6. Reinstall the caliper and secure it with bolts, tightening to the manufacturer's torque specifications.

4. Brake Line and Connection Inspection

Tools Required: Wrench set, brake line wrench
Sub-steps:
1. Visually inspect all brake lines and fittings for signs of wear or leaks.
2. Tighten any loose fittings and replace any damaged lines or connections.
3. Bleed the brake system after replacing any lines to remove air from the system.
