Rotors rubbing on calipers!!

[haveahotcarl]

One of my calipers locked up so I decided to replace it and the other one but I ran into a problem. I got the so called "great" Auto Zone remanufactured calipers and everything looked legit. Dimensions appeared similar, fit appeared perfect they looked almost identical, until I drove. I heard a horrible metal on metal grinding and removed the wheel to find what can be seen in the picture below.

My question is, can I grind down that side so that it clears the rotor? It would probably take only 1/8 inch down to fix it. They are aftermarket rotors, EBC, but worked fine with the other "stock" calipers. (they may have been changed before, i don't know)

I would remove it all and reinstall. I would not how ever grind off a chunk!! I reman caliper isn't going to add metal. so it must be an install issue. I but some where a bolt is wrong, or something. Grinding off a chunk is the wrong solution though. The fact that it could have been a bad install could lead to death when it fails

The calipers aren't exactly the same. My thought is that they are just the wrong part. It seems that parts places NEVER have correct replacement parts for our cars. I blame it on someone who "upgraded" their brakes on a regular Protege and brought back the standard Protege caliper cores and claimed they were Mazdaspeed.

I checked the install over and nothing is awry. It is just the wrong part.

You probably have the STOCK Protege caliper and not the Mazdaspeed. That explains the rubbing of the rotor on the caliper.

Exactly what I thought. I just ordered the OEM calipers from Mazda. Brand new (no reman available) I am just tired of dicking around with trying to get the right parts for my brakes. Better safe than not stopping.

How did you get the caliper back on if it was rubbing so much?

Not rubbing a huge amount. Everything seemed to go ok. All the bolts lined up exactly as they should. It wasn't huge. The silver paint makes it look like the grooved were deeper. Probably less than 1/32 of an inch rubbed off. It actually felt more like a brake pad was rubbing when I moved the car except making a horrid noise.

There is a difference betweek the MSP and protege calipers, they mount on the same braket so they may fit but the rotors are different. Double check the part number and go get your stock caliper back if you turned it in as a core. The stock caliper can be rebuilt, that's what I'd do. I don't trust the parts guys anymore, if a part needs to be replaced or remaned I make sure they use my part and that they don't paint the part so that I know I got my original part back. Have had to do 3 green axles so far and they have all gone back the same part. I don't know what the exact difference there is but I do know it is different so I do it that way.

If it's the front get a caliper for the 2002 Mazda 626 with the 2.5 v6. It's a direct fit. The only difference is color, but if you paint your calipers it won't matter.
I picked up a brand new one from pepboys for like $50 in stock they wanted like $75 for the MSP one special order...That's some expensive paint!!!
I think the rear is specific to the MSP

can you change to the ms6 front brakes for a factory big brake option? I think i read that somewhere

the rear pads and rotors are mz6 exchangable, caliper is not.

That's good to know.

I have also read about a MS6 conversion being bolt on

 

[Aricjm15]

Ms6 brakes are huge, and very different.

 

[43975]

I guess that's a no go on the MS6 conversion

MS6 FRONT brakes will bolt in fine. You will need the cage and caliper and new pad and rotors.

very tempting...MS3 get the same setup or no?

Do you have a write up someplace on that?? pics??? How to??

the MSP caliper bracket is different also... though I never tried fitting a normal protege caliper on the MSP bracket so I can't say whether that works or not

98-02 626 V6 front calipers fit as MSP replacements, though not exactly the same, works the same

What exactly is the difference? I'm considering replacing just one (it has a slow leak). Is there a big enough difference that changing just one would be a bad idea?

the MSP ones came with a silver powdercoat.
