I'm chasing my tail on a simple brake job.

Build date is Jan 11, but I swear I have small clips, cause the "wrong" set I brought home first time were larger.

Now I have brake wobble {rotors turned} & it looks like I have possibly ANOTHER incorrect set of pads (stock # comes back as "not for your vehicle" on their [O'reily] site )

I have the original pads for measurement, it looks like a 40mm witness mark on them.

Right now. I can only find 1 set on line that even MENTIONS that there is a "large clip" size.

Does any body have firm numbers on actual measurements or info?

I'm looking at a Power Stop Rotor & pad kit # KOE5571 , but I can't get through their help line to ask.

 

 

Well,

You can see an engineering ID # number:

FM 3136 CSFF

Which I surmise is "Ford/Mazda brake pad (the 2136 part) & a few revisions

Google yields an address on a Farm to Market road in Texas...

I figured this would have come up before but several different searches gives me bupkiss.

 

No body has any info on caliper piston size change for 2011 & how to ID correctly?

 

TBH I'd put that question to a Ford parts Dept.

 

At any rate, took receipts & box back and had a discussion with counter person @ O's.

He/we did a bunch of computer cross referencing.

Indeed I had gone home originally with "big clip" pads & the ones I eventually installed were small clip alternate part # pads, but the number was indeed good.

Can't say why they are there, since all documentation I CAN locate says that production didn't change over to small clips until 4/11.

I've got the Powerstop daily driver pad & rotor kit on order from Rock.

Hope this helps any '11 owner who has the same questions in the future.
