So 3 weeks ago I went with stoptech slotted front rotors and stop tech pads. Loved them on my previous cars and compared to stock prices were $20 more.

Installed them, they stopped... everything was peachy.

3 weeks later, today I and seeing an astonishing amount of rotor dust (red in color) - 2 trips to work and back (30 miles) and the fronts are covered in brake dust. I will post pictures. I figured more dust than normal from the start is normal but 3 weeks later and especially the amount I’m seeing after 60 miles...

Happening on both wheels not just one.

Anyone with stoptechs get something to similar to this? I have a “claim” in to stoptech to see what they say.

Will post the pictures I have later

Good rotors, terrible pads.

Go with G-Loc pads

without any info on what pads you're running its hard for anyone to tell you.

slotted rotors will eats pads faster. stoptech street and higher pads will produce more dust. it's a by-product of stopping.

Man and I wanted some Stop-tech pads and rotors when it came to time to replace them. Might have to go with some cheap Lifetime warranty pads from O’Reillys.

hmm interesting, I had stoptech powerslotted rotors and hawk Hps pads on my Speed 3 when I had the car. perfect combo. had "some" bite while they were cold but once they heated up good lord they really had some bite. id try swapping the pads to hawk. I even ran some Akebono pads on my Gs350 fsport paired with the 2 piece aluminum rotor to help with brake dust vs oem pads and surprisingly those worked out very well.

yea ive never ran their pads . just rotors paired with another pad like HAWK

Its brake dust. Go drive a german car and you will then see what real brake dust is like! Some pads produce more than others.

Performance pads = more braking, dust, and noise (in most cases).


Some pads will be better then others. Every mod is a compromise somewhere.

so was on the phone with stoptech and buybrakes (where i got them from). Sounds like the brake pads I got arent a good "fit" to the application I have.

I have ran stoptechs on my bmw and honda's before this never had any issues which is why it was so surprising to see.

This is the kit I bought (my price was reduced so dont start ):

Hello Mike these pads are for an aggressive option if you want less dust use the Ceramic option this would be the lowest dust pads we have but you give up some bite..



Use 105.09761 ceramic for less dust

Thank you
-----------------------------------------------------------

Not a tremendous amount of help - just a eh buy these instead... I felt the description is off from what is displayed from stoptechs - and speaking with him later said these are for "heavy industry standards" aka lots of towing, heavy heavy braking... he (roger @ stoptech) was unsure why they are paired together in the first place...

Going back to buybrakes and speaking with them - they are to sort this out with Roger @ stoptech today and give me a call... Customer service right now is up in the air as to how good I am getting.

Like I said I have had 308 pads before on my cars (1 with CCW's - for those of who know what these are, brake dust on polished wheels shows up like no other) and never ran into issues (they just bite more)

I dont have the box but they believe i was given the 309 pads instead due to the increased brake rotor dust.
Per the description on buybrakes:
Note: If you would like to upgrade to the 309 StopTech Performance Brake Pads that are rated for high performance, fleet, police and Truck and Tow use, give us a ring and we'll upgrade you if there is an upgrade path by kit number or specific part number. Or, search under StopTech Stage 3 Truck and Tow Kit.

3 days to and from work (30 miles round trip). 8 stop lights 1 way (usually hit green lights).



Imgur: The magic of the Internet

Yes better performing brake pads will produce more dust. Brake dust is the #1 complaint from Mercedes and BMW owners, quoting someone in Motor Trend magazine, "shut up and wash your car." I think he/she said something about being a slob too.

That buybrakes website is terrible.

They list these as the parts:
Street Pack - Slotted - Single Axle
1 x 105.09761 Front Pad
1 x 126.44174SL and 1 x 126.44174SR Front Disc
1 x 308.09761 Front Pad
1 x 126.44174SL and 1 x 126.44174SR Front Disc

So they're selling you a "front brake kit" that's got two different sets of pads and four rotors? All for the front?

Also if you purchased 308 pads those are StopTech Street pads, not PosiQuiet pads like the first image shows. Second image shows the actual Street pads box.

Chances are you have Street performance pads, not PosiQuiet. The description of the item mentions 308 and says street. Check whatever the box was that they came in if you haven't thrown it away to see what you actually were sent.

Seems like everything was ordered correctly, you just didn't realize that their main product image was mis-representing and that PosiQuiet pads aren't in the order.

correct. I should have gotten the posi quiets or 308s (as they are pretty much the same per BB) but instead got the other ones (they think 309s). Which is what I was complaining to BuyBrakes about.

They list part: 105.09761 which are Centric's Posi-Quiet 105 Ceramic Brake Pads are easy on price and deliver great low-dust performance over your OE pads with better bite.

they list those in the "description" near the top but that's just the part number.

all the rest of the page in the product details and such they mention the street or 308 pads which aren't the posiquiet

i'm not arguing that you're in the wrong here, but the fact that they list two sets of brake pads and 4 rotors in the main section should have set off some alarms before ordering to verify what you're actually getting.

sure lesson learned...

99% of the time usually the descriptions are alike from the manf. site to the distributors site (copy and pasted literally word for word). Here not the case. Was in a hurry ordering them. However either way I should have gotten then 105's posi quiets (part list break down) or the 308s which i followed up on a near close match to the 308s (which are provided in the description). They think i got 309s (which are a selected upgrade for heavy applications).

Again lesson learned. I started it to wonder if anyone with stop techs was seeing significant brake dust issue (i get aftermarket pads will produce more... but i dont think anyone realizes how bad this is... -1pt for me for not posting pictures). Suppose to get a call from Buy Brakes last night... to my surprise they never did... (whomp whomp) the guy I talked to was saying they were going to send me the right pads for the mistake (if there was).
