Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Locate the brake caliper and remove the caliper bolts using a socket set.
3. Carefully slide the caliper off the brake pads and suspend it (do not let it hang by the brake line).
4. Inspect the brake pads: if they are less than 1/8 inch thick or show uneven wear, replace them.
5. Install new brake pads by sliding them into place and reattach the caliper.
6. Torque the caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper and pads as outlined in the previous step.
2. Remove the rotor by unscrewing the retaining screws (if present) and sliding it off the hub.
3. Inspect the rotor for grooves, warping, or discoloration; if damaged, replace with new rotors.
4. Clean the hub surface with brake cleaner before installing new rotors.
5. Mount the new rotor and secure it with screws.

4. Brake Fluid Inspection and Replacement

Sub-steps:
1. Locate the brake fluid reservoir and check the fluid level; add new brake fluid (DOT 3 or DOT 4 as specified) if low.
2. If the fluid appears dark or contaminated, bleed the brake system to remove old fluid.
3. Use a brake bleeder kit to remove old fluid from each brake line, starting from the wheel furthest from the master cylinder.
