Solution

1. Preparation

Gather tools and parts.
Jack up the vehicle and secure it on jack stands.
Remove the wheels to access the brake components.

2. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned and seated.

3. Inspect and Replace Brake Rotors

If the rotors are scored or warped, remove them by unscrewing the rotor retaining screws (if equipped) and sliding them off the hub.
Install new rotors, ensuring they are clean and free of grease.
Torque rotor retaining screws to manufacturer specifications.

4. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications.
Reinstall the wheel and secure lug nuts to proper torque.

5. Final Checks

Pump the brake pedal to seat the pads against the rotors.
Check brake fluid level in the master cylinder and top off if necessary.
