500 miles on my SRT8, I need new brakes ?

They do not.

New for the 2006 model year, however, is a set of front multi-piston calipers (don't know who makes them) for the Quad Cab SRT10 with 15" (380mm) rotors. The regular cab SRT10 gets the old floating front calipers.

Thanks for the clarification. So that would be an apples/oranges scenario comparing the SRT-8's to the SRT-10's.

Dzeckhausen,how many miles do you have on your srt8?Are you haveing any brake issues ie brake dust and or rotor scoreing.If you are haveing the same issues most of are what would you reccomend as the soulition.My car has only a few hunderd miles and i can not belive the heavy brake dust and rotor wear.Thanks in advance

I have now Placed 1200 miles on my new SRT8 and have noticed the groving in about 500. Have been driving like an old lady too, not hard on the brakes at all. Other than that and the dust, I love this car though...

As of today, I have 2,511 miles on my SRT8. I am experiencing exactly the same rotor scoring and heavy brake dust as everyone else on the forum. I'm in the brake business, and I've never seen so much dust and such an aggressive attack on the rotors by any street pad before.

My solution is probably not the ideal solution for most of you. I'm removing my Brembo calipers and rotors and replacing them with much larger brakes from StopTech with 6-piston calipers and Hawk Performance Ceramic pads. With those brakes and pads, my dust problems should go away almost completely.



According to the Hawk National Sales Manager, the Performance Ceramic pads will become available for the SRT8 sometime late this summer. If you're not up for dropping $5795 on a 4-wheel big brake upgrade to solve this problem now, you might just want to wait for these new pads.

Dayum! One of the reasons for getting the SRT8 package was its awesome Brembo brake package. Probably not as insane as the Stoptechs, but not doing any autocrossing either.

I guess I'll wait 'til the summer to replace the pads. I concur, had the car for 300 miles and the brake dust is ridiculous!

something you can't really appreciate it until you actually see it first hand...

Well, I don't need new brakes but my rotors are already grooved pretty good after 300 miles. I took my car into the dealership today for the window tint they owed me, and asked them to take a look at the rotors. I now have 500 miles on the car. The attachment is what they gave me when I picked up the car. I've seen this problem throughout the forum, and even saw it on the live SRT gab last night. Thought the attachment might be funny to some of you. Well, maybe not funny

By the time I was done talking to the service rep, they were trying to get someone on the phone from corporate. Sounded like they were sick of giving out this lame document and having their customers screem.

Moose.

Update, my file was too big to attach...let me try again...be right back

Okay, here it is.

Yep. That is lame. From what they said last night, hopefully something positive will come of this. We need to keep complaining.

If you consider one of the performance aspects of the rotor to be its expected lifetime, then this most certainly does affect performance! The pads on the SRT8 are so aggressive that I anticipate many customers will reach minimum thickness in just a few thousand miles.

First of all, this is a high performance braking package, some noise may be present since performance is the number 1 criteria in this brake package

When you design a brake package for a street car, you don't make "high performance" the number one criterion at the expense of all other considerations. You don't see this sort of issue with Porsche, Ferrari, or Lamborghini cars fitted with factory Brembo brakes, nor do you see this with the latest Dodge Viper, Subaru WRX STi or the Mitsubishi EVO VIII. There's nothing specific to Brembo calipers and/or big rotors that requires the brake package be noisy or chew up rotors in 500 miles. This all comes down to the inappropriate selection of brake pads for a street application. Either the pad manufacturer has poor process control and there is a problem with particle size consistency in the friction compound, or the compound is not appropriate for street driving. It's as simple as that. Pick a better pad and the problems will go away.

This issue is still under investigation, no test vehicles exhibited this condition so it was somewhat of a suprise(sic) when the issue showed up in the field.

That statement makes me lean toward a pad manufacturing problem as the cause. On the other hand, the cars may have been driven so aggressively during testing that they were essentially under race conditions. Certain race pads (e.g., Hawk Blue) are quite rotor friendly when running at 500 degrees F, but are incredibly abrasive when run at the lower temperatures one might expect to find during normal street driving. So it's possible that SRT Engineering didn't perform adequate "everyday driving" tests on the SRT8 prototypes.

Timing on these changes is still a couple months away before they will be available to the field (tenatively(sic) August or September 2005).

The letter was updated on 12/29/2005, yet it still claims the resolution will be available in September of 2005 (last year). That's a bit odd. You would think they would revise the availability date to some time AFTER the letter was updated.

Bottom line - this problem will be solved by the aftermarket in spite of the best efforts of SRT Engineering. I expect the new Hawk Performance Ceramic pads will eliminate the rotor scoring issue. The only catch may be an increase in pedal effort. I have no idea what the operating coefficient of friction (Cf) of the factory SRT8 pads is. If the Hawk pads have a much lower Cf, then pedal effort will increase in proportion to the change.
