The Tesla Parts Catalog (for the US) naturally lists brake parts for Model X (2015-2021), with several parts shared with Model S (2012-2016 and 2016-2021). The Performance models of both Models S and X received red-painted calipers; non-performance models received gray calipers.) For example, here are some shared part names and part numbers for Models S and X from this "Classic" period (to simplify I've omitted rear Brembo brakes, which were on the Models S/X along with separate rear parking brake calipers until ~2016/17):
So far, so good.
However, at Tesla and at certain online sites selling new and used Tesla brakes, some otherwise attractive brake products are designated with "M12" in the name/description. When asked, so far sellers have not been able/willing to satisfactorily explain what "M12" signifies, and if it is universal (to all Tesla Models S & X brakes of this period) or specific (to only certain Tesla brake versions or geographic areas, like the European market for example). No one so far can or will tell me if this an important factor for ensuring compatibility?
Having sometimes seen (arguably devious) sellers remain "silent" to North American customers about European Type 2 charging adapters and Model X European tow-ball hitch adapters, I now tend to be suspicious.
Anyway, is "M12" a Tesla thing, or does it emanate from the manufacturer: Brembo. I have so far not seen "M12" used to describe Mando brakes in the Tesla Parts Catalog. But "M12" is used in some front and rear Brembo brake Tesla part names. In the following examples (emphasis added), I have separated the Model-Years that share "M12" caliper parts and used colored arrows to indicate shared caliper part numbers:
My car does not have Brembo rear brakes, so I don't have to concern myself with the "M12" issue in the rear. But what about in the front?
Thanks for any assistance you can offer. If anyone can recommend brake experts in the Sacramento, California area, please let me know. (Feel free to PM me to discuss.)

- Does "M12" refer to the caliper-bolt thread size? (E.g., a metric 12 thread size?)
|- Model S 2012-2016, Model S 2016-2021, and Model X 2015-2021 seem to use the same M12 bolts for front and rear Brembo brakes (emphasis||added):
- Part Name: BOLT HF M12x1.75x45 8.8-ZnFl
- Part Number: 2007068-00-B
|
- And they use a different M12 bolt for rear Mando brakes, if they happen to use those (emphasis||added):
- Part Name: BOLT,TE,M12X45,STL[109],ZNFL[BLCK]
- Part Number: 1088968-00-B
|
- Model S 2012-2016, Model S 2016-2021, and Model X 2015-2021 seem to use the same M12 bolts for front and rear Brembo brakes (emphasis||added):
- Or does "M12" refer to something entirely different (like the brake line connector size, or something else)?
| - If it is about the bolt thread size, and all Tesla (Classic Models S & X) brakes use M12 size bolts, why do only certain calipers show "M12" in the part name?
