Brakes have vibration when applying them at high speed. I had a long road track day last week and on my last lap on the way back in, the peddle felt like it was on a wash board. It went away by the time I got home. But this last weekend I did some highway driving and slight vibration came back. I did a little research and think I baked some of the pad to the rotor. So my ? is: Do I need to get the rotors turned ever slightly to remove baked on pad? Should I replace current pads, and if so is Hawk HPS for the street and Hawk DTC-70 a good choice for for track day? Or just a long shot I take it to dealer only 5K on ODMeter (RSAs show wear on outer corners) and if they say I was racing it should I say SRT- STREET & RACING TECHNOLIGY, thats why I bought it.
I thought I read somewhere that you shouldn't turn the rotors, on the SRT8...basically, it's a replace only part.
Take some pics of the rotor with the wheel off and we'll be able to tell you more. If you stopped and held the brake, like at a stop sign, shortly after coming off the track, then yes you may have transfered pad material onto the rotor. Otherwise, the rotors may be warped from the heat generated on the track. You can turn the rotors a few thousandths to get rid of the pad material without a problem. A friend of mine had to have it done. If your mileage is that low, I'd take it in under warranty for brake vibration. You may get all new rotors out of the deal.
I had stock pads and rotors. The rotors have some darker bluish streaks on them. Maybe trying to get new brakes and rotors from dealer isn't a bad idea. If the tech dosen't ask or realize the wear on the shoulders of the tires. When I have another track day should I go with a Hawk Pad and get a spare set of rotors.
When at the track I have found making a nice slow cool down lap is key to keeping the brakes from warping or pads sticking to the rotors. Never put the E brake on or keep your foot on the brake for any extended period after running the car at the track. If you do that you run the risk of transferring pad material or warping the rotors. I have done several track days and have my original rotors on my car w/ 34k miles and have had no issues. I have however used the EBC redstuff pads, not the stock pads. These pads work great for street (low dust) and also do well at the track too. They also make the Yellow Stuff Pads which are an even more track oriented pad. Here are the EBC pads http://www.bmcspeedshop.com/SearchResults.asp?Search=ebc+6.1 We also carry Hawk, but they do not have a track pad out for our cars yet to my knowledge. I think they just have the HP and HPS currently. http://www.bmcspeedshop.com/SearchResults.asp?Search=hawk+charger
You don't have to go to different pads or rotors for the track. In fact, I love our stock pads at the track. The big point to take away from this is to NOT hold the brake at all after coming off the track. Using your cool down lap, as a cool down lap will help tremendously too. Last time I was at the track, when exiting the track I would downshift all the way to first and then drive around the paddock to cool everything down before using the brakes again.
i know when i was making numerous high speed runs in west texas on my way out to spring fest, after my last run (the one that i got pulled over on!!!), i made a quick jab on the brakes to begin to slow the car after seeing the cop (out of habit i think). i then had to quickly come to a full stop. after i was done, i noticed now the car has a shake at high speeds when applying brakes. sucks, but i am sure it was due to that relatively quick full stop after doing over 140 and having to hit the brakes!!!
Thats probably what happened on the last lap I made it started to drizzle and the track started to get a little slick, I entered a long apex to hot and slide off the rumble boards and got the black flag to come in I didn't get to cool down and I stopped to talk to the starter before entering the padock, I probably baked some pad on the rotor when I stopped and talked to the starter for about 10 sec.
Brought the car in this week to Norwood Park Dodge, I told the service manager that I had a vibration in the brakes at highway speeds. I call at the end of the day and what do they say: SORRY YOUR WARRENTY IS VOID, YOU CHANGED YOUR SUSPENSION, EXHAUST AND AIR FILTER. Man was I pissed!!!!!!!!!!!!!!!!!!!!
Just kidding. The gave me new rotors no questions asked. Norwood Park Dodge is the place to get service!!!!!!
I,m going to track in June any advice on how not to cook the brakes again I don't want to push it and try to get another set of rotors on Dodge. Are Hawk pads a better pad for the track?
