I broke a front brake caliper bracket mounting bolt today while re-installing the caliper. I was torquing it to the specified 148 ft lbs when I heard it snap. Luckily it was not completely broken into two pieces and was able to back out the bolt.

It is a M14x1.5 10.9 50mm flange bolt.

Since it is Sunday afternoon I had to settle with a M14-1.5 8.8 50mm hex blot and washer from the hardware store to get it back on the road. Loctite used on reassembly.

Problem is that no where can I find any reference to the M14x1.5 bolt; all references are for M14x2.0 which I could had gotten at the hardware store but mine are definitely M14x1.5.

Do I have some alien Expy with non-standard caliper mounting brackets?

Any and all comments appreciated.

 

Do you have 2wd or 4wd?

 

My Expy is a 2WD XLS

 

That explains it, the bolts are different for 2wd versus 4wd with 4wd being much more commonplace.

 

Well crap! Any idea where I can find a replacement?

Is it a dealer item?

 

Any good hardware store should have 10.9 grade bolts on hand....

 

Yeah, the problem that I've encountered is that I haven't been able to find a M14x1.5. All that I've been able to find in M14 10.9 is 2.0 threads. Just saying.

 

You just have to know where to look!

These 2 bolts are identical except for one has threads all the way up and the other doesn't. Choose your poison.

no m14x1.5 flange bolts, but plenty of regular hex bolt/cap screw.
