Looking at vendor pics and FSM, I don't think they have them on the rear of the W123/107 calipers either. At least for ATEs.

I have never owned a W124, but looking at ATE catalog, heat shields show on front, but not on rear where there is much less heat.

I have a W210 too - Fronts are quite a different design from my older cars.

Its probably because I have 220D. 60 hp. 65 on mine with match ported and polished head (hey thats a 10% gain!).

So I would say its a consensus in my application.

For others, it depends how you drive. If just a cruiser, its unnecessary.

The analogy is there is a backing plate that sticks to the pad that replaces the fragile ancient heat shield. It disperses heat. Is way more durable. And wont get bent up on accident or rust away over time. I didn't see any heat shields anywhere for my car. I choose my calipers by the coating on them. Galvanized.

Its redundant to install both the backing plate on the pad and the heat shield. They are both for the same purpose, and the new design is an updated way to do it.

As well, the pad material itself has changed. It dispenses heat better.

However, in these older applications did you know you are supposed to run organic pads? So messy. But the rotors are softer and anything else is supposed to eat them up.

I was on my last turn on my rotors. And I would rather not clean my rims every drive. So I put on semi sintered. Its new rotor time after these anyways, and I will see what it does. Maybe the tech on those has changed as well.

Its kind of how it goes with an old car. Tech improves and following the fsm on some things is kinda silly.

Just like updating to pencil glow plugs.

On another note, with squeaking, I like to use that red spray can stuff. "Anti squeak" it is sometimes called. Ive seen it happen once, so I have to say it, the spray goes on the backside of the pad! Lol.

You call ATE, I already know what I need. Lol.

But have a good day. No big deal.

Here's what I'm talking about. This design has replaced the original heat shield. It is a heat shield. But it simply goes on the pad, not into the piston in the caliper.



If you want to go fast and get fancy, get some from these guys.

At about $200, go for them! Ohoh - They don't seem to have them listed even for a souped up 220D

I am out of here!

Lol. That style "heat shield" will come with your pads, if necessary. Advancements in the composition of the pad materials may require no heat shields. I would be concerned running organic pads. If semi-sintered, its unnecessary, in my application.

No need for titanium. Those are for hardcore racers. If you are provided with nothing, and want some, summit sells some more ordinary ones. I also have cut my own for strange applications.

Its the modern version. Like pencil glow plugs.

They will always sell something if people will buy it. Even if it doesn't make sense.

But you can use either method. Both will work. Only the only style will bend and rust and need replacement eventually. The new style is replaced every pad set.

If doing a proper oem restore, of course get the old style. But at that point, goto the dealer.

resurrecting this old thread - because I just bought rebuilt, authentic ATE front calipers for my 300d at NAPA. No heat shields are present. When I asked about this guy said this is the way they are doing them now, they are not part of the current design. There really wasn't anything to argue about - no amount of "i read on the internet" was going to change the situation because NAPA Ate calipers do not come with heat shields - at least as of 4/23/2016. I suppose I could have demanded my money back and stormed out - but I needed the calipers, he had the calipers, and they look to be in great shape and carefully assembled.

The question I have now is - do I attempt to install my original old rusty heat shields into my new calipers? Don't even know if I can get them out without significant struggle and bending/damage.

Hey the NAPA rebuilds I installed also had no heat shields.

NAPA rebuilds them right and uses authentic ATE parts. Unlike other flaky sellers...

You can try to carefully install your old heat shields but it takes some tact and skill to get them in right...or buy new ones online..

Ya have to install just right...

For anyone who bought rebuilt calipers without the heat shields, it would be advisable to install them if you want a lasting repair. Main obstacle seems to be actually finding heat shields rather than having to fork out a few more $$$. Why the rebuilders leave them off is a puzzle. Our small shops in Toronto include them as a matter of course - don't even have to ask.

No one seems to sell just the heat shields, but some have a low cost kit that includes the shields.

Interestingly, you can buy the rebuild kit from Mercedes Benz and it DOES include heat shields It is sold right here on Peachparts!
