When should I change my front and rear brake pads? I checked the front pads and they are a little more than a 1/4 inch thick. What is the recommended wear or thickness before replacement?

Thanks for your time

Generally they MUST be changed at 1/16 or sometimes 1/32.

But I would change them now, remove them and check the condition or the rotor, they should be turned or at least cleaned with brake clean. If there are any groves or uneven wear, have them turned or replaced.
Check condition of calipers, hose connection, slide pins, bolts. Replace any worn parts.

Rear pads generally do not wear as fast as fronts, but if they are 1/4" or lower, replace them.

Use good pads, not the 1 year specials. Wagner and Bendix have a "wear" warranty, so if they wear out you get replacements free. Most other "lifetime" pads are warranted against manufacturing defects not wear. But the wagner and bendix are usually twice the initial cost. So use them if you intend to keep the car for several years.
