What tools are needed to change front brake pads for 2006 Toyota Scion Tc?

You'll of course need a jack and a lug wrench to remove the wheel. A 14 mm socket and/or 14 mm open end wrench to remove upper caliper bolt. You may need some anti-seize or WD-40 to break the caliper bolt free. If after using either of these, the caliper bolt still won't break free, use a steel pipe on the end of your wrench to give you greater leverage. Do not use the pipe when tightening the caliper bolt. Use a "C" clamp for compressing the brake piston since its been extended by your brake system hydraulics to fit the worn out pad; this will give you plenty of room to install the fat new pad. You'll need a torque wrench to torque the caliper bolt to 25 ft. lbs when you reinstall it. Also use the torque wrench to torque your wheel lugs to 76 ft. lbs for stock wheels or as recommended by manufacturer for aftermarket wheels. you'll need the same tools to do the rear pads, except you will substitute 17mm socket and wrench where you previously used a 14mm.
