So, the lower bolt on my passenger side caliper is gone, I have no idea where I lost it, I think coming over the Buckman down here in Jacksonville. My question is, does anyone know the part number for a new bolt? or any suggestions on where to find one, I'm thinking the Napa store or Autozone. Any suggestion would be helpful.

 

Sec...

 

I lost one years ago after having a friend help me paint my calipers. I'm assuming he didn't properly tighten it.
I'd just go down to the dealership or give them a call, should be a quick fix.

 

Hmm, don't see the part numbers on the manual:

 

Looks like either "2" or "7" depending if he needs the guide pin bolt or the bracket bolt.

OP: If all else fails, You should be able to take the other one to there hardware store and match it up. The proper thread pitch, diameter, and length in grade 5 is all you need. The head size probably wont be the same but its not a big deal.

 

I found them in the fiche... the three pages for the front are attached.

Thanks everyone! I took the print-out to the auto-port here on base and the tech had one ordered for me I'm going to pick it up today, you guys are awesome!!!

 

33698C is the part number for anyone else who has this problem in the future, it took me all of ten minutes at the hobby shop to put it on, no problems as of yet. though just to be clear the bolt is 7 bucks, if this happens to you get it taken care of ASAP, the bolt is cheap but if you lose the retaining pin (which the bolt screws into) your looking at 35 dollars for a new pin. Easy day thanks for your help again everyone.
