Just a thought.

Oh, yeah...by the way....this is in a sticky at the top of the site called Aftermarket & OEM Modifications DIY/FAQ

Again, I think a permanent sticky of all the brake jobs would be helpful. People could list the different types of pads & rotors they've used plus where they bought them and the price in one handy place.
Brakes are probably the one maintenance item that many people can do themselves (they just don't know how) and can save a boatload of money versus the dealer. I mean, the dealer charges what, about a grand to put in new pads, replace the sensors and turn the rotors? It looks like you can do it yourself with aftermarket parts (and probably superior parts, at least as far as dust is concerned) for under $500.
Sure, the added benefits of the Porterfield's are quieter operation, better stops, less fade and longer life. But I bought them because they are virtually dust free compared to OEM.
Look at your front wheels after two weeks without a wash. I'd bet you a cold, frosty mug of ale that mine are cleaner.

Anyhooo, FWIW, list price for 2003 C240 MB pads is $73, my dealer charges $88 when I asked, Duval's online price is $54.75, Vivid's 15% off price ???
For anybody who has experience with these pads, did your's have the hole in the pads for the sensor which I don't have, or is it the metal tab I mentioned above?
(I know I can find locate them from my old pads but I want the right pads before I start disassembling anything
)I'll try to get a picture up shortly...
Thanks for your help.

The inside pad wears out at a different rate to the outside pad. That is the 80 / 50 rule for pad wear. Hence the alternate sensor locations relating to physical position.

Some cars take the outer reading, some cars take the inner. Some cars take only front readings and others take one reading front and one rear. This is only for W203. I bet there are even more variants I am not aware of.
Arrow 1 shows a small hole on the side which is on 2 of 4 pads in the set.

Arrow 2 is the medal tab I referred to in the previous post.
Arrow 3 is where I thought the hole would be be (drilled through the pad from the back to the front)

Is arrow 1 the hole which holds the sensor? It appears it is drilled into the edge of the pad, parallel to the surface of the pad. Orginally I imagined it as a hole which goes through the the back to the front of the pad surface.
It is not hard at all. As soon as you take the caliper off the disc and then the pads off the calliper it will all make sense to you. Make shure you depress the calliper pistons before you take them of. Use a screwdriver. Have fun.
I use Porterfield brake pad, very nice, brake dust is less than the back wheel
Also, read the detailled instrictions. The pads (at least the ones I bought) are unidirectional. The pads with the sensor holes are the inboard pads. The other two pads (without sensor holes) are the outer ones.
Did the front and back. The back pads, in case any body in the future references this, are held entiry in place by the spring clip. So once the pin is tapped out the smaller square pads will slide right out - no need to remove any bolts or anything. Its real easy.
Oh yeah, unlike the DIY Brake Pad instructions written for an 02 C230, the bolts to remove the front caliper require a 18mm socket not 17mm.
The information is presented as reference only. This information is not an instruction guide.
The vehicle has about 76k miles. There’s probably another 5k on the pads, more if winter weren’t coming.
The polishing was with a right angle die grinder and the woven mesh pads.
Removing the rotors was a pain in the butt. Using a propane torch, I heated the drum, but not the hub. It wasn’t going anywhere. Then I shot the joint with WD-40 and heated the drum again. It popped right off. I got identical results on both sides.
Do not polish either side of the machined surfaces where the caliper is bolted to the knuckle.
The caliper remained connected. Do not allow it to hang by the hose. The caliper was not split.
The GiroDisc caliper spreader from Zeckhausen Racing is an excellent tool. It is very easy to bottom-out the pistons.
The hubs were painted without masking the rotor. I just buffed the paint off the rotor after drying.
All bolts got Loktite blue. The pin got anti-seize.
