2016 rear drivers side caliper bracket wrong bolt size with new caliper

I’m blown away at how complex this has gotten.

Rear brake job (just pads) slide pin broke off in driver side rear caliper. Couple hours of drilling and heat threw in the towel since I couldn’t get it out. O’reilly to autozone both pulled 2016 rear drivers side brake caliper and the OEM mounting bolt is too big to thread into the NEW caliper bracket. Absolutely NOBODY can tell me why the hell I can’t buy a new caliper for my truck and that I am “out of luck”. Is there something that I’m missing that my truck out of Toyotas fleet of 2016 SR5 4WD 5.7 V8 is the ONLY one with a bigger mounting bolt for the caliper bracket? They even searched by the trucks vin in their system which came up with the exact same part they originally sold me which has a smaller hole on the bracket.

please, any advice.

 

Pics of problem area might help. Seem to have about 30% of the information about your problem. A pin is seized, but you’re looking for a bolt. Are you trying to replace the entire caliper and bracket? Just the caliper? Just the slide pin? Do you still have the original factory caliper or one you bought from the auto parts store?

 

Tundras built after 08/2015 use larger caliper bracket bolts than prior to 08/2015. The newer, larger bolts on the rear should be M14x1.5.

The easy way to get the right thing for a later build 2016 is to buy a caliper for a 2017.

 

Correct, as I see it listed before 8/15 is 12 x 1.25 bolt size, after that 14x1.5 size.. The counter person should see that listed on the screen, before and after manufacture date..so I just looked and the only place so far I've seen the manufacture date listed is on Rockauto..

 

I ended up drilling out the pin completely. Threw a new pin in there and made it work. I will definitely be using Rockauto to get a correct caliper since these local stores cant get me a correct caliper. Even asking for a 17+.

Thanks for all the help!

 

I am having this exact problem right now except I have a 2008 Tundra and my Caliper mounting bracket bolts are m14x1.5 and the mounting brackets from all the parts stores have m12x1.25. This makes the holes on the axle piece larger than the bolts it calls for. I can not find a bracket with m14x1.5 anywhere.

 

Did you buy the truck used? I’m thinking it’s had a newer rear axle transplanted into it…

 

I am the second owner. It was purchased new in San Antonio TX. Brand new by Texas Brine company and shipped to western NY. No one at the company knows and the dealer was absolutely no help. Thinking I'm gonna drill the slider pin out.
