Welcome! This is a thread on how to change your rear brake pads using OEM Mazda Brake Pads. Easy step by step instructions and pictures guarantee you not to get lost at all. I made this DIY for fellow RX8 Club members! (and because i needed to change my rear pads). Enjoy. Trust me you will have no questions because this is as detail as you can get with pictures!You are going to need a Disc Caliper Tool Set which can be rented from Autozone for free! ($55 deposit) and it looks like this.
Now put two bricks or chocks in back of both your front wheels to keep your car from rolling back start to jack up your car. When always jacking up your cars use jacks or jack stands in pairs. I just used two jacks. Your car should look like this. http://i397.photobucket.com/albums/p...Y/SDC11329.jpg
Once you have taken both wheels off, you should see your brake system and go back to your tools and get your socket wrench with the 14mm socket it should look like this, if you grabbed a hammer put it back! (lolz jk) http://i397.photobucket.com/albums/p...Y/SDC11334.jpg
First start off on the passenger side and start to remove the top caliper bolt by turning it in the direction of my finger (clockwise) it should look like this http://i397.photobucket.com/albums/p...Y/SDC11335.jpg
First get the new inner pad and insert it in the caliper. The inner pad is the only one that has a clip. Make sure the clip is at the top like this. Important: only the rear passenger side pads has the clip, that is why i said to start from the passenger side! If not u F'd up and have to start over. If you did it correct and are at this picture then continue to the next step and good job. http://i397.photobucket.com/albums/p...Y/SDC11349.jpg
Now place the tool to the caliper piston like this. The two nipples at the end of the tool should insert into the cross in the piston. You should be here, if you are then begin to turn the tool handle in the direction of my finger (clockwise) and only turn the piston as far back as you need to be able to put the caliper back down over the pads,. http://i397.photobucket.com/albums/p...Y/SDC11355.jpg
It is important the you followed the previous step and especially the underlined part. The reason i said "only as far as you need to clear the pads when you pull the caliper down is because the "+" or "cross" part of the piston needs to slide into the nipples of the back of the inner brake pad. You can see the nipples on the pads, they are next to the CE530. Heres a picture http://i397.photobucket.com/albums/p...Y/SDC11356.jpg

If your caliper went back down correctly and there is no gap between the piston and pads then congratulations and continue by inserting the top caliper bolt back by moving it in the direction of my finger (counterclockwise), like this
Congratulations you are now half way and continue to the driver side rear brake system and take of the top caliper bolt in the direction of my finger (clockwise) like this http://i397.photobucket.com/albums/p...Y/SDC11366.jpg
Get the Caliper tool kit and turn the piston in the direction of my finger (clockwise) and like I had said before, only as far back as you need to clear the pads when bringing the caliper back down. http://i397.photobucket.com/albums/p...Y/SDC11375.jpg
Now Lower you car back down and tighten both the rear driver and passenger side wheel nuts. Congratulations you are now done and earned some experience points! You are very welcome and if any questions PM me! P.S.! Dont forget to wash your hands with GoJO! or your wife/GF will slap you if you try touching them. As you can see from the time on the pics it only took me less than an hour and thats with taking pics! BOOOYA! http://i397.photobucket.com/albums/p...Y/SDC11383.jpg

Amazing write up! I have never done this as I was sacred I was going to mess up my brakes.... and I kinda need those... but what about this grease stuff... where would you add this even?
most pads come with little packets of what they call anti squeel grease.. you apply it between the caliper pistons and the pad shims..

You add the grease between the metal clips on the back pads and pistons. That is all.

Great DIY -thanks so much - I just had my wheel off today scoping out the project so your timing is impeccable.
I few questions:
1) I am getting new rotors, too - do I remove the entire caliper from the two bolts which are behind the caliper (i.e. not the same one you removed to just change the pads)?
2) If I decide to paint the caliper (and the dust shield behind the rotor), does anyone have any suggestions for a good technique.
3) If not painting the caliper, do they need to be cleaned with brake cleaner as part of the regular maintainance of changing the pads?
4) Best technique for bedding?
Great DIY . Thanks much, it will be handy when I do my brakes soon.
I noticed that the rubber dusts seal around the pistons looks deformed after they were turned back in. I think the trick to prevent that is to turn them in slow and check them after each 1/4 turn.
I've used the needle nose pliers method in the past.
Shop manual says to "Verify that dust seal is installed into groove of the piston securely."
Service manual minimum thickness:
Pads: 2mm for both front/rear.
Rotors: 22mm/front , 16mm/rear.

The rubber seal can be carefully removed off of the piston, add a couple of drops of brake fluid into the groove for lubrication and slide back down into the groove. It will not deform and will help keep it from cracking or tearing.
that is great just what I needed as have to change the pads on mine you should think about doing a online work manual what you have done here is better than my manual I will use your step by step for doing my pads...much appreciated.
It's really important with the rear brakes that the piston is retracted completely into the caliper body. If it doesn't go back all the way, it appears that the parking brake actuator mechanism ( a worm gear drive of sorts) doesn't let the piston retract and release properly...and the pads will drag.
This doesn't appear to be a problem if the pads are new...they won't fit otherwise. But it has bit me in the *** when I was swapping back in used track pads
so after turning the piston back and lowering the caliper, the piston should pretty much graze the inner pad?
no0b
I just replaced all four brakes with new Hawk HPS pads, (which by the way, come with the metal pieces all ready on them). And I rotated the rears all the way in as Dan mentioned. Seemed to work fine this way.
Question: Is the process exactly the same for front brakes. If not can someone explain the finer differences in procedure?
More or less the same. One big difference in doing the fronts:
You need a piston compressor tool or a c-clamp (which is what I use) to push the front pistons back into the calipers.
Anyone else have a hard time reading it?? The front can be pushed back in with the same tool kit.... with the front you dont have to worry about lining up the "+" of the piston to slide into the inner brake pad like the rear. The front simply requires the piston to be pushed directly back in. A C- Clamp would do.

It's not terribly hard but it's not very easy. Maybe put some spaces between pictures and text? That would help I think.
+1 !!!!!
I read the whole thing and saw all the pics.
but seriously, put single/double space after each picture link wont hurt
oh one more thing, one day photobucket will "disable/delete" your pictures. so you might want to host them somewhere else, or just re-size them to something smaller and upload it all on this server.
I found a lot of DIYs with dead picture links for the same reason and most of those DIY creators are either moved on to other cars and never came back, dont have backup of the pics, or has pass away.
