Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Brake Fluid Inspection and Replacement

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level; if low, add the specified brake fluid (DOT 3 or DOT 4 as per the owner's manual).
3. If the fluid is contaminated (dark color or debris), proceed to bleed the brakes.

Tools Required: Brake fluid, funnel, clean rags

3. Brake Pad and Rotor Replacement

Sub-steps:
1. Loosen the lug nuts on the affected wheel, then lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Remove the caliper bolts and carefully slide the caliper off the rotor.
4. Inspect the brake pads; if they are worn down (less than 3mm thickness), replace them.
5. Remove the old rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
6. Install the new rotor, ensuring it is properly seated.
7. Install new brake pads into the caliper bracket.
8. Reinstall the caliper over the new pads and secure it with the caliper bolts.

Tools Required: Socket set, torque wrench, brake pad spreader tool, screwdrivers

4. Brake Caliper and Line Inspection

Sub-steps:
1. Inspect the brake calipers for leaks or physical damage.
2. If a caliper is found to be faulty, disconnect the brake line and remove the caliper.
3. Install the new caliper and reconnect the brake line, ensuring no leaks.
4. Bleed the brake system to remove any air trapped in the lines.

Tools Required: Wrench set, bleed kit

5. Final Assembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer's specification.
3. Check the brake fluid level again and top off if necessary.
