I did my brakes about 2 months ago and they've worked great so far until a few days ago when I heard what sounded like a rock smack the floor. I towed it back and jacked it up only to realize that my front drivers side caliper was missing the bottom bolt holding the caliper to the rotor. Went to 5 different places and none had them so I ordered directly through Honda which I reviewed the exploded view with the tech to explain the bolt.

I get it in today and much to my dismay, it's not the right size. Looks exactly like the other caliper bolt but no go. Am I missing something here? Do they really have two different size bolts for the top and bottom to mount the caliper to the rotor? Any help would be appreciated. They're closed now so I can't go back until tomorrow.

 

I would remove the other caliper bolt take to a auto parts store and match it up with a new bolt . i have bought bolts like this at auto parts stores just make sure that the grade of bolt is good

 

Switch the passenger side's same bolt to the driver's side. That way you can say for sure the problem is the bolt and not the hole. Those bolts are torqued to 80 ft-lbs btw.

 

The parts drawings on the Acura estore show a pin A and pin B which have different
part numbers. These are the pins the caliper slides on. The bracket is mounted with
two 10 mm bolts which should be the same top and bottom.

 

Go to Autozone... Get Slider + Bolt (Duralast) set for 7.95+tax = Problem Solved.

 

Just a thought... the caliper has probably probably rotated on the remaining bolt and now the spindle hole is not aligned with the caliper bracket hole. Try loosening the remaining bolt and rotating the caliper until they align.

 

Like skirmich says get the kit from auto store. It will have bolts and sliders that will fit.
