To replace brake pads, first, lift the car and remove the wheel. Locate the caliper bolts and loosen them to access the pads. Slide out the old pads and inspect the caliper for damage. If necessary, compress the caliper piston using a C-clamp. Install the new pads, ensuring they fit snugly. Reassemble the caliper, tighten the bolts, and put the wheel back on. Finally, repeat the process for the other side and test the brakes before driving.
