Yep. I chose to keep my stock ones to save money but the 626 or MSProtege ones will work. EDIT: See original post, I found out after driving some more that the oeiginal calipers wont work with the 626 brackets. When you get the brackets be sure to get the 626 front caliper's as well.
The calipers are different in some ways (slightly different casting and the pistons in rears of the 98+ 626 caliper need to be turned in rather than pushed in) but the piston diameter and parking brake are the same.

I was at the yard today, saw a 929 and the brake seems to be bigger just like the newer 626. I might go back next week end to see if their hardware will work just like the 626 ones.

I was thinking the same thing today.
The rotors will work on the 98+ 626 mazda 6 and mazdaspeed protege.
The calipers and brackets though are different. If they work they likely have to be used together it dosnt look like the brackets will work with our calipers or the other way around.
The bolts holding the bracket to the hub are larger also.
I lost patience with the bolts so let us know how it works out.
I have some other ideas for swaps but if the MS 6 brakes work I'll be satisfied and move on to somthing else.

I doubt Mazda6 rears will work at all - from my testing (I have a set of the 280mm rears here from a Mazda6) they don't bolt up to the knuckles I have ie the bracket is wrong, the mounting bolts are spaced differently. But the calipers are basically the same.
Have a set of the Sentia/929 rears to try coming any day now...
i was thinking about this.. what about upgrading both front and rear by using different peices? let me explain.
you take 2002+ Protege5 rear calipers and pads, use 99+ 626 front and rear rotors, 99+ 626 Caliper brackets front and rear. then you could maximize the front braking power from the larger Rotors/pads from the 626. and maximize the rears with the larger protege 5 rear caliper and pads, plus the larger rotor. Am i making sence here? i believe this would make everything but the caliper itself larger, but increase the braking area and reduce heat thus better breaking. Also Hawk makes pads for the 626 and protege so its win win everywhere! im going to do this when my brakes need to be changed
I am thinking of doing almost the same thing. I'm gonna use the Protege5 rear calipers and 626 rotors in the rear. The front will get the M6 rotors with the MPV calipers, with proper brackets and Hawk pads all the way around.
I'm curious, on the front, why use the original old mx6 caliper with the newer 626 pad? Why not just go all the way and use the 626 caliper too? Cost? I'm just worried that even if the 626 pad will fit in the older mx6 caliper, it might be best to use the proper caliper-pad combination. I'm going to assume that if the pad is bigger, the 626 caliper may be a little bigger and therefore has a little bit more contact area with the pad and so it would distribute the force to the pad more evenly that using the older caliper would. Am I making sense? I haven't seen it of course so I'm just speculating. Has any one compared the two calipers side by side that can comment?
I really like what Beemsmx6 is thinking about 626 rotors and protege rear calipers.

The pads used are determined by the bracket not the caliper. To use the P5 pads you need the P5 bracket wich apparently only works with the P5 caliper. Using the 626 rotor you would need to use the 626 bracket wich dose not fit the P5 pads.

I havent done that swap. Ask I4mx6 though.

The pistons are the same size between the two calipers. I compared them at the yard and decided to save the $$ add keep my original front calipers. I replaced one rear that was siezed to the original bracket. EDIT: Again see original post, you need the matching 626 calipers for the front.
If/when I replace the other calipers I'll buy the newer 626 / 6 calipers Because they are different castings and I believe they were upgraded to be stiffer making for a firmer and more consistant pedal feel.
I ofcourse cant yet confirm the 6 parts will fit but all the pics I have seen look identical to the 98+ 626 pieces I have. The 6 owners are using the 626 pieces to save money.

I tried to do this tonight, and it's not possible to use the stock calipers, you NEED the 626 calipers. With some force and using the smaller 626 slider pins you can get the mx6 calipers to work. But, it' half-assed since the sliders are too small, not to mention it looks like the caliper is rubbing against the pads. The piston is definitely big enough on the mx6 calipers, they just don't have enough clearance.
Anyone doing this should definitely get the calipers also. I have to go back to the scrapyard tomorrow to pick up the calipers...wish I'd just taken them right from the start.
This post applies to the front only, I don't know about the rears. The rotors are about 1/2" taller than the mx6's, and the venting is narrower meaning there's more metal. Not to mention the difference in pad size is substantial, so it's still a very worth-while upgrade. The total cost of brakes from the scrapyard with brackets is less than $40 so the price difference is neglegable.
The pads used are determined by the bracket not the caliper. To use the P5 pads you need the P5 bracket wich apparently only works with the P5 caliper. Using the 626 rotor you would need to use the 626 bracket wich dose not fit the P5 pads.
So what would be better for the rear? The P5's larger pads on the original mx6/P5 rotor diameter or the original mx6/626 sized pads on the larger 626 rotor diameter? How do auto engineers figure this stuff? I'm sure there's some mathematical way to plug in rotor diameter, pad size, clamping force, and pad coefficient of friction to figure this out. If you have to make pad friction the same and hope clamping force is the same (or that you know what it is for each if not the same) and then, knowing the rotor diameters and pad surface area, you can see which is best, right? So anyone know how to do that? or does any one just know which is best without having to do that?
So for the front, is this 626 upgrade the best/cheapest/easiest for our cars that requires NO machining, drilling, grinding, special brackets, spacers etc. Is there anything better for similar budget? Is this the holly grail of brake upgrades? I've found plenty of threads about upgrades but it's either for very pricey kits, requires more skill than I have to pull off, or leaves me worried about ABS compatibility, master cylinder size etc etc. I'm really enjoying this tread because it seems really inexpensive and no harder than a normal brake job. I like the idea of just getting the 626 stuff, bolting it on, and driving off. Thanks guys!
Ok, it's an all 626 rear upgrade then. But I'm going to use the MPV 2 piston fronts even if I have to use the 10 3/4 MPV rotor. I'd prefer to use the 626/M6 11.1s and will see if that will work. A used rotor out of a junkyard isn't that much to see if it's possible. Might have to even pay around with some brackets, but it's worth it IMO.
Then there's the Volvo S40 4 piston calipers, but that's a whole other story....

Okay, I have too much time on my hands. Here's what I found comparing cardone remanufactured part numbers. Prior to 1998, all cars use the same stuff. Interestingly, the 98+ 2.0L I4 626s continue to use the same front brakes as the earlier pre-98 2.5L V6 mx6/probe/626s. (I think the 2.0L I4s had rear drums though??? but I'm not positive)
As has been posted, after '98, things change. Comparing the pre and post 98 2.5L V6 cars, the REAR brake calipers withOUT bracket are the exact same part number. WITH the bracket, the 98+ 626 gains an "A" designation - presumably for the larger bracket while the basic caliper remains the same. However, the FRONT calipers are TOTALLY DIFFERENT part numbers. Presumably, as Renboy found out, while they will bolt right on, they are NOT the same.
