Some cars only use two - one on the front and one on the rear. The theory being that if one side's pads hit the sensor, then the other will be worn down as well, and as both sets should be changed together, why bother with another sensor.

I cannot remember if mine had two or one on the rear. The 230 has two...

If your car is to be well serviced, then you will never need the sensors as you will change the pads before they get that low.

Worry about having the front ones working, they are the important ones.

Yeah, you got it right! It's only 2 in front, and 1 in the rear. That's how it's supposed to be. :thumbsup:

Are you going with ceramic pads and silver arrow rotors?

You will be AMAZED at the difference the SS lines make. They feel like *real* brakes after that, instead of the too-soft spongy feel you're used to.

They look nice!

I have always wondered, what's the advantage of "dimpling" the rotors instead of drilling them? Must be some logic behind it...

That's what I heard too but I went for drilled anyway because in case of rain they seem to dry faster and collect less water or at least that's what I understand using drilled rotors. Please correct me if I am wrong.

Cheers.

Anything done to increase the 'exposed' surface area of the disk rotor will help cooling. So drilling gave the most surface area but also weaken the disk (slightly). Dimple also increase the surface exposed to air and it does not weaken the disk. Slotted disk provide channels for water to 'spin' out, and also increase the surface area.

If you are racing you may crack the drilled rotor.
Otherwise you are safe.
The idea is to have clean pads, and throw the gasses out.
And like Mick/ msbarsi says, they are good in the rain.

Hmmmm.
I got to go. No I better run, I think I got some gas. ;)
I know I am going to get in trouble with this. LOL.
S*T I have them, & love them.
Look cool too. ;)

Regards.
aam.

Joe I think any known brand of DOT 4 brake fluid will do the job. I have always been advised not to use DOT 5 but I've never understood why even if I've always thought about it.
I know it's not that much of advise but that's all I know about brake fluids.

Hope it helps.

Cheers.

In a nutshell, DOT5 is silicon-based fluid, and DOT3 and 4 are glycol-based fluids. The main factor in brake fluids are their boiling points. DOT 5 is generally a better product if you don't change your fluid annually or biannually, because it doesn't attract water like 3 and 4 do.

Problem is, silicone is a "softer" liquid, and is around 2X more compressible than gycol is. So the pedal feel with DOT5 might not be as firm as with 3 or 4. But at the same time, it maintains much higher operating temp capacity, because it doesn't pick up the water that SOT 3 and 4 do, and the feel will be a lot more consistent over time. So like anything else, it's a trade-off.

Generally speaking, if you aren't tracking the car, and you stay on top of your maintenance (e.g. don't mind changing the fluid), then you'll probably get the best performance out of using DOT 4 and changing the fluid once every year or two. If you're one of those people who never change the brake fluid, then DOT5 will work best for you.

Hi Joe.
Thanks for asking my advice.
But as usual it comes with plus. ;)

I think any good quality brake fluid that meets dot 4 and manufacturers requirements is OK by me.
I am not a Mercedes parts fanatic, I go for the after market but with careful choices,
I go for the Mercedes parts makers, but with out the star mark on them.

I go for Bosch on electronic parts, Febi on fluids, Bilstien struts. Etc.

As long and it mixes with the existing fluid/
I also have used Castrol dot 3-4 with no problems.

Hmmmmmmmmmm.
You mentioned that you have posted it in R129.
( That's us.)
I wonder where else have you posted it in, may be in one of the P#$% sites? Haha.
You bad boy you.
I would not install the silicone stuff in............
It is OK for fun clutches, tits and nipples.
( Oops, did I misspell something? )

But I will keep it away from ABS and the suspension mechanics.

Regards.
aam.

PS.
Like msbarsi and Chris have said, I go along with them.
