Solution

1. Preparation

Gather necessary tools and parts.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket set.
Carefully slide the caliper off the brake rotor.
Remove the old brake pads from the caliper bracket.
Inspect the caliper pins for wear; lubricate if necessary.
Insert new brake pads into the caliper bracket ensuring proper orientation.
Reinstall the caliper over the new pads and secure with caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

3. Check and Replace Brake Rotors (if needed)

Inspect rotors for thickness and surface condition.
If replacing, remove the rotor by unbolting it from the hub.
Install new rotors, ensuring they are clean and free of contaminants.
Torque the rotor bolts to manufacturer specifications.

4. Brake Fluid Check and Replacement

Inspect the brake fluid reservoir; if low, top off with the specified brake fluid (DOT 3 or DOT 4).
If fluid is contaminated, bleed the brake system to replace old fluid with new.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to seat the new pads and ensure proper brake feel.
Test drive the vehicle at low speeds to verify functionality.
