Hi,
I'm thinking of buying new brake pads for my 83 300d, I'm a novice
at this, and when I go to different sources, some sell just the brake pads,
some the brake pads with sensor. I can't find a definitive type or model
number to look for. Are the brake pads different for the Year or Model
of the Mercedes?
I found these on EBAY, different part numbers. Are both or either
ok?

Thanks much

The brake pads for a 300D are different front and rear. The brake sensors are the same for all 4 wheels. I would recommend that you buy the brake pads from your local auto parts store - in case you need to return something you will get an immediate response. Prices are very comparable to Ebay. You can also try Peach Parts, but once again there is a delay if you need to return/exchange something.

This is for the '83 300D?

Indeed front and rear pads are different. If you're getting front pads, you should identify what brand of caliper you have. There are two brands. ATE, and Bendix. To identify which you have you'd need to pull the wheels off and have a look. The brand should be stamped in the metal. Also, the pad retainers are different. The ATE use pins through the caliper that just tap in and are held there by friction - the spring underneath the pins is a one piece deal. The Bendix pins have holes in the small tip where a cotter goes through to hold it in. The springs are two pieces.





Once you know which you have, you can buy the pads on this website. Textar is a good brand.

One the W123 there are only sensors on the front pads. No sensors on the back. Note that the car will operate just fine without the sensors. Installing them is good form, but in reality they are "dummy light" triggers to tell you that your pads are low. You can never install them, and just check your pads from time to time, or you can install them later. That is, if you don't want to order them now...

On an '83 300D, brake sensors on the rear axle don't exist.

Pads on a 126 are the same between brands of calipers ie Bendix/ATE. They are different between front and rear.

On the 126, wear sensors are readily available for a couple of dollars each at the local parts store.

Did Mercedes do something different on the 123?

I suggest buying calipers locally unless you are buying new (which is expensive). Shipping on reman returns and the convenience of local exchanges easily offsets any price savings. I'm planning on driving my current cars long enough to need warranty replacement.

Yes, 123's are different. The pads for ATE calipers won't work on Bendix and vice versa.

Incidentally, you can put W126 front rotors and calipers on a W123. I'm getting ready to do exactly that. I've already done the parts and procedures research. Now I just need to shop around for the right parts at the right price and then overcome my resistance to spending money.

I have another thread going on similar subject.

Having a problem choosing pads because this site has a different front pad part number and thickness as compared with what epc and some other vendors say.

If you have alloys and care how they look, Akebono Euro Ceramic pads are great for keeping wheels looking clean. Decent price at Amazon. To my braking foot, ceramic pads don't have the initial bite of organic pads and require more effort in general braking but they haul you down from speed without issue. I have to keep more distance now that I'm MB less

Sixto
MB-less

The ceramics I have had were wonderful on dust and bit more than the stock pads so less pedal pressure was needed for a given level of braking. I had Hawks.

The rear Brake Pads, W115, W116, W123, W126 are the same as are the Rotors. Not sure on the second generation W126 86 - 91.

There is a thickness difference on the front pads as I remember on the w123`s, but don`t remember the change over date or chassis number. Your part guy should know when he looks up the part and year of your car.

Too many times I have seen on E-Bay where they list some part that will fit all W123`s 77 - 85. Not always so.

I don`t install the brake sensors, but I rotate my tires and do a visual when I do. The sensors are good for the majority of people that are not DIY type people and just stick the key in and go till something happens like a light coming on in the dash.

The pad sensors came in handy for me on the SD.

One caliper failed, the inboard piston was stuck on.

Don't know how long it was, but the light on the dash would flicker. This alerted me to inspect the issue. I was able to save the rotor that way.

Question: Is the only difference in 123 front pads the initial thickness? If so, one could use the thinner pads regardless of caliper brand.

Yes, and that is exactly what has been stated previously in this thread.

It's not just on eBay.

In researching front pads for my 85 300D with ATE original calipers, I was first given a heads up here that I would need 15mm pads instead of 17.5mm. I found that Pelican, AA and one other vendor warned of this problem. But other on-line sources did not.

Even MBUSA's EPC said the front pads for my particular car should be 0014209920 (which are the 17.5mm pads). But footnote says they are for Teves calipers (Teves=Ate, I believe) from chassis 150315 (mine is later).

I can only suppose that Ate calipers installed as OE on the later 123s are not same as aftermarket Ate calipers. Otherwise how would the 17.5mm pads fit?

In any event, I ordered the 0014207820 15mm pads based on what I learned here.
