How do you replace the front brake pads on a 1989 Nissan Maxima?

Raise the front end of the vehicle. Support it securely on jack stands. Remove the tires. Turn the steering wheel either all the way left or all the way right whichever side you are doing first. Use a 14mm wrench remove the lower caliper bolt, using a big c clamp, collapse the caliper piston. Lift the bottom of the caliper all the way and remove it from the bridge, then remove the brake pads and install the new ones the same way installation is reverse of how you removed the caliper.
