I've searched... cant find anything and i'm getting really bitter.

It's the passenger rear caliper. I just need to kno how to take it apart and everything. thanks

 

It's really a straight forward procedure. You just unscrew the piston, and take it all apart. I will be doing a tutorial shortly. As soon as I can get my one question answered:

I already have all the pics for the fronts, but am waiting on my question to do the rears...later

 

go to zoomautoparts.com they have a rebuild kit for the calipers and i think that the kit comes with instructions on how to do it....

 

Get the factory service manual at the link found in the FAQ at the top of this section. Also, the Haynes manual is also helpful.

 

Besides replacing the rubber seals, o-rings, and boots, you really need to hone out the cylinders for proper sealing. Most toolstores (sears, northern tool, etc..) and autoparts stores (advance auto, autozone, pep-boys) have that tool you use with your drill.

Powerbuilt Tools Brake Cylinder Hone: 3 Arm; 3/4" To 2-1/4"

 

I have been under the FAQ and put in factory service manual, and there is nothing found

 

Why would you hone out the cylinders?! It's the rubber seals that provide the seal. Honeing out the cylinders will only make the cylinders bore larger for no reason. Is my reasoning flawed?

 

Honing the cylinders smooths them out and removes scratches and ridges. We're not boring out piston engines 30 over here.

 

It's there. All ya gotta do is look.

I don't want to buy a shop manual for my car, is there a place where I can still find out the information from one
Shop manuals for both series can be found on-line at:

No damn. They are 40$ at oreily auto parts for the front 4piston calipers remand the whol caliper and 80 for the rear. With that why on earth rebuild them ontop of that they allways leak :-/

 

Not everyone has access to a "oreily auto parts"(never even heard of it) store, and mazdatrix.com rebuild kits(about 32$) are the cheapest alternative. Plus when you do it your self, you know it's done right. As everything else on this car seems to be this way...

 

Ok, I see. All the ones I have done so far have had totally flat bores so I guess I'm good...

 

I have rebuilt all of my calipers. I used the FSM only and rebuild kits from an auto parts store. Make sure you do it right. If there is any doubt you can do it correctly, just get reman calipers.

Also, to get the pistons out/in of the rear calipers, I reccomend the "brake caliper piston tool". Just ask at an auto parts store and they'll know what you're talking about. It looks like a little rubix cube that you can attach a 3/8ths rachet onto and turn the caliper pistons out and in with. Some people use needle nose pliers with success, but I think "the tool" makes it alot easier.

 

Oh yeah. It makes things a **** ton easier.

 

I've found it pretty straight-forward, i did the rears with no "how-to" or service manual to help me. As you disassemble it, you'll see where all the new seals need to go.

I also took the time to hone the cylinders.
