Hey buddy, its for all 4. 2 x fronts & 2 x rear.

I looked on the Porterfield site and couldn't locate the cabriolet version. Does anyone know if the sedan pads are the same?

Sanch

same pads

Are the porterfield pads any better at braking or is it a purely brake dust driven decision?
Louder, better bite or better fade resistance? My brakes get cooked on a fairly regular basis.

Sanch

No noise, feels much better than OEM. Less break dust is an added bonus.

For the fronts, they seem to show two options: the R-4 for $389 or the R4-S for $299. Does anyone know the difference?

auditoamg

They told me to select R4-S.

I didn't go quite as crazy as you (and I mean that as a complement!), but I also pulled each wheel off today to try and treat them to more easily shed brake dust. I cleaned them thoroughly, then sealed them with some Wolfgang's Deep Gloss Paint Sealant because:
1) I like how it looks on the body paint
2) I had a bunch on hand

After sealing them, I topped them with some Armor-All Brake Dust Repellent, which I actually like quite a bit. Really helps shed the dust; it's just tough to get it on the inside barrels when they're mounted.

I then detailed the car itself: washed w/ Dawn to strip any existing wax, dried, then broke out the Porter Cable random orbital. I spot-buffed a few minor scratches w/ some Menzerna 1500, then polished the whole car with Menzerna 4000 SuperGloss. Then hit it with some Zaino Z-2 Pro polish for gloss/shine, and topped with some Meguiar's Ultimate Liquid Wax (which for $15 at Wal-Mart I REALLY like for durability) for protection.

I can't stand the amount of dust any longer. Just ordered a set of Porterfields front and rear.

Sanch

I was exactly like you! - I just had enough, the poterfields are pretty good. My fronts barely have any dust at all. Rears are doing much better also.

I don't need to wash the wheels as often anymore - I get it washed once every 2/3 weeks along with the car now. Before I used to do the wheels weekly

nobbyv

I know I'll go that way eventually, but my cheap side says I should at least try to get 10k out of the stock pads...

auditoamg

Same here.... MY cheapside and YOUR cheapside have clearly been in discussions, of late.

I'm also VERY curious how these pads will impact the rotor life, over time. OEM pads have to change rotors every other brake job, or so.... Will these be better or worse????

Just popping in to say that I recently changed for Porterfield R4-S, front and rear.

exremely happy! Noise on existsnt, brake dust greatly reduced, and stops feel a lot stronger

Just got my car one week ago with the matt black wheels. Just noticed today that there is so much dust. Calipers are brownish and rims have gone from matte black to almost a rust looking colour.

See63esS

Put on the Porterfields today. Looking forward to much less dust.

Nice Ride

This may also be an option. Anyone try them? I did not have a chance to put them on yet....https://mbworld.org/forums/new-s-cla...p-dusting.html

Just wondering if anyone can tell me if there are low pad indicators on the rear pads as mine have just gone down to metal without any warning last night.

Ive contacted Porterfield for an eta to Brisbane as I now need pads urgently but haven't heard back from them yet.

I could book the car into the service centre today but being Saturday I'm not to sure if the parts department will be open to access genuine pads.

If anyone in brisbane has access to genuine or aftermarket pads today (Saturday) pm me please.

Come to think of it, if anyone in Australia can get pads to me please pm me.

RDO247

Has anyone done a diy rear pad change?

RDO247

Just thought I'd share some photos of my rear brakes.

I replaced the rears with genuine pads at a cost of AU$550 (trade price not retail) including low pad sensor and $230 labour (not Mercedes service).

Note to all, no warning light for low brake pads came up and I got caught out a long way from home when I first heard the dreaded metal on metal sound on my left rear disk rotor.

The low brake pad indicator is only on the right rear pad, drivers side for RHD, passenger side for LHD...

On inspection of the pads you can see the uneven wear from left and right pads and the uneven wear on the damaged left side disk and worn down to metal pad.

Not to sure why the left side wore quicker then the right but point to self, don't rely on the low pad indicators to warn you that your pads are getting low.

New genuine pads and a light disk machine and I'm back on the road.

Metal pad backing on metal rotor eeek!

Genuine pads and low brake sensor
Brake sensor did not activate due to uneven wear from left and right sides

Sanch

That is good to know... That's quite odd about the uneven wear.

Good to hear you're back on the road - If you don't mind me asking how many kms have you done?

Will give me a good indication when to look out for mine lol

Just got the warning light at around 18,000 miles. Going with Porterfield, but man are they expensive. Twice as much as MB pads but, if they are dustless (almost) and stop better then I suppose thats the way to go.

I might add that the rears are the ones setting off the warning, the fronts have about 25% life left.

Guilty

I have them. They stop better, last longer, less dust, but still a lot of dust. I'd go with them over OEM pads any day of the year. I love them.

Sanch

I find one thing odd about the poterfields, the fronts seem to have next to no break dust in the fronts... the rears however do have a build up of break dust after 2 weeks - Still better than OEM.

Do you face a similar issue?

CT-AMG

Based on my experience with OEM pads, the rears work twice as hard, wear out twice as fast and produce twice as much dust. makes sense that the porterfields would have similar results.

Sanch

Thank you, that makes sense then.
