2003 f150 need caliber.. help
 

I have been looking for a caliber online at autozone, ect. They offer so many and all of them look slightly different in shape and part numbers are different. Which one is the right one? I need front passage caliber it's not catching. Truck takes way to long to slow to a stop when brakes are applied. Can I rebuild or should I replace?

If replace which one? I'm second owner but trucks well used to haul landscape trailer so need good brakes.

4X4? Extended Cab or Super Crew? Offroad and towing package? Long wheel base or short? Need to know some particulars about your truck first.

P.S. it's Brake Caliper

With so many choices I would replace both front ones just to keep the braking even side to side.

Yeah, we need more info as F150Dad said. Autozone usually carries remanufactured bosch calipers. They work great, but will surface rust pretty fast. I would replace both sides. Depending on the condition of the rotors and pads, you might want to replace them also. Autozone always has deals on Duralast Gold brake parts. Make sure the brake hoses are in good shape also. What do the rear brakes look like? Hauling a trailer you want all your brakes working at their best.

I just took a look on rockauto.com and the big difference between the calipers listed seems to be the number of wheel lugs on your truck. How many lugs does your have and what size engine?

My truck is a XLT / Supercab / 4x4 / FX4 with 5-Lug.

Oh, mine is a 4.6L, but that shouldn't matter. It would be the same as a 5.4L.
