I'm shopping for front calipers my 2012 Tundra base model 2WD 4.6 V8

I'm seeing some that are noted as 12 x 1.25mm Mounting Holes. How do I know which ones I have?

I have a stuck piston on one side so I am replacing both sides. Along with new rotors, pads, lines etc as well.

Thanks in Advance!!

Are you absolutely positive the piston is stuck? I've seen it before where you get premature pad failure and diagnosis is a bad piston, but most times its just rust build up behind the pad guide. It builds up and doesnt allow the pad to float like it should.

yes sure, removed pads and one of the pistons on the outer passenger side would not budge.....
Pads are still good..rotors are warped AGAIN!

Now, do you have any idea about the question in my post?

Or the OP could save a ton of money by going to Rockauto.com and get his parts.

That is exactly what I did. New hoses, calipers, pads and rotors. The front only, cost me about $450
