Brake pad replacement

Nothing real earthshaking here, I simply took pictures while doing some work, and a search will bring up something for folks to look at.
All this started trying to make the smoke-bomb worthy of a drive to see the Austin boys and get a little diagnostic help. I had metal to metal noise coming from right rear, and you can see why.

Brake caliper rebuild

Well, the brake job lead to caliper issues. They were both bad. RR was stuck 'on' on outer RR pad, LR caliper just deteriorated, but I think was working. Kit was easy to install, and let me tell you something. It doesn't take much air pressure at all to pop out the caliper pistons. I was skeptical, but they shoot out with purpose. You just have to figure out a way to get them BOTH to pop out.
The Skinnerbox link to service manual said NOT to seperate the caliper halves, so I didn't. That makes it a pain to clean out the rust and debris where the pistons go, but with scotchbrite it will eventually come off OK. As long as it isn't pitted when you remove the rust.
Like I said, it was easy and cheap ($10.81) for the kit. The new caliper for the RR came from O'Rielly's, and was $41.00. I broke a piston on that one before I tried the air method of removal. My mistake, but being that stuck it was probably just as well.

Brake caliper styles

Here is a question. I now will have two different style calipers, as I will note with a pic. One has larger diameter pistons, but I assume fluid will push whatever opposes it.
ALSO, heed folks advice on replacing brake lines. It has been explained that they ruin from the inside, and the fluid can force the brake 'on', but the fluid can't release said pressure as comprimised brake lines act as sort of a one-way valve. Mine looked terrible inside. I can't do anything to the front at this time, but I'm sure they must be horrible also.

I cannot tell from the photo, definitively, but it does appear that the pistons in one caliper are larger in diameter, on the outside, then the pistons in the second caliper.

If this is the case, you cannot use them on the vehicle.

Remember that the brake force generated is proportional to the area of the face of the piston. A larger piston will apply more braking force and the vehicle will pull.

It almost appears as if one of the calipers is not proper for the vehicle.

There are 3 different kinds of calipers on the Skinnerbox link to the shop manual. The piston diameter is quite different.
I hate to hear about not being able to use one of them.
Sigh.......

Well, sorry for the bad news, but, you definitely need two calipers that are identical (left and right, of course).

I would agree as apparently the piston sizes are different. This would probably explain why one side wore down quicker than the other?

They were both the same size. The one with the smaller pistons is the new one from O'Reilly's. I bet my core is gone from the store also. I guess I'll return the new one and try and find a RR wagon caliper to rebuild.
I am truly getting to hate this car.

I had the same run around from O'Really's with the brake calipers on my car. If they don't give you the correct make of caliper the hardware will not fit either. You may have to lean on them and ask to check their computer screen. I went to their website and looked up the part # myself. (3 trips and they still charged me $1.95 for a bolt I needed at the time. )

From the pictures from the first post on this thread, does anybody know what kind/brand of caliper that is?

Here is a link that discusses the 3 different calipers.

From what I can recall and from checking out a couple of things on Fastlane, it appears that the caliper with the larger piston is an ATE which uses the "flat" metal anti-rattle clip. The ATE also is a little "beefier" in appearance. The Bendix uses a heavy "wire" z-shaped clip. If you check where the clip fits the caliper, you should be able to see a difference. The original appears to be ATE and the replacement, they gave you, is a Bendix. This is exactly the same scenario I had to deal with.

I hope I found the mistake. I got my receipt, went to O'Reilly website, and the one they sold me was "exc 300TD". That would be "except 300TD". Duh!
So are the pistons on the rear of sedans smaller than the pistons for the wagons? Maybe any of the three wagon calipers has the correct piston size. I would still like to order the same. I can't tell by marks or lettering on the caliper.
Thank you SD Blue, for snapping me into a little investigation. I'm appreciative.

The very first picture shows the folded sheet metal cross that gently holds the pads in. That is like all of mine, front and back, which are ATE.

Thank you very much SD Blue and Lycoming-8!
I went to Fastlane, and I wonder if ACEI brand is comparable to ATE? I hate that Fastlane is $30 bucks higher, though. But this website has saved me over $30 in the past.
