Thanks!

Like the last poster said check to see if the rear rotors are vented.

But I can 100% garauntee that you have the BRY (Standard antilock) brakes.

BR1 (European Antilock)
BR6 (Heavy duty brakes) use the same rotors and rear calipers.

I have the heavy duty brakes and they are not slotted. The HD brakes only came with the towing package.

Sorry guy, speed rating has zero to do with how sticky a tire is. I had a set of Firestone Z-rated tires on my Mach-1 Mustang that I could smoke in 4th gear. The Z-Rated Bridgestone Potenza's I replaced them with I couldn't smoke in 2nd gear. Speed rating is just that, the highest sustained speed the tire is stable at. You can get crappy, slippery Z-Rated tires just as you can get crappy, slippery H-rated tires...

Re: Anyone change brakes and rotors yet? Any DIYs or tips??

Stay away from drilled rotors. They look cool but thats about the only advantage they have. Unless you are spending the bucks for rotors with the holes cast in ie Porsche most drilled rotors suffer from cracking and warpage and will shorten pad life.

Also break in your pads and rotors. Find a large empty parking lot that allows you to hit speeds of 70mph + or -. Lot should also allow sufficient distance for to go from 70mph to approx 15mph. Now you ant to make several runs and go from 70 mph to approx 15mph or less but do not come to a complete stop. You want to smell the pads and with some pads they will off gas and you will notice fade. Once the pads get smelly drive around and let things cool down. Avoid stop signs and stop lights if possible. Repeat bedding process 3 to 5 times.

The original purpose of the cast in holes in Porsche rotors was to allow the rotors to off gas.

You dont need to spend big bucks on a big brake kit to get better brakes. A quality rotor, Earl's braided brake lines, a high performance pad, and a fluid with a high wet oiling point will help. Getting air to the brakes is also important.

Re: Anyone change brakes and rotors yet? Any DIYs or tips??

The HD brakes require the wider caliper for fitment. I replaced Rotors and Pads. Dealer Paid for Rotors and I paid for the Pads and I did the install as it was part of the purchase deal since the brakes vibrated on the test drive. Vehicle had been sitting for six months and had been driven in Ontario for one Winter so after driving around for two weeks the Rotors were still too rusty. Dealer complied and the install was straight forward. I put a dab of blue thread locker on the caliper mounting bolts and torqued them to same spec as my LX Car. Although not related to changing the brakes, The hub nuts were pretty rusted as water collects around the center cap via machined steps on the rims and seems to sit in there. Cleaned up with work wheel and coated with anti-sieze. Painted Calipers with Light Blue Caliper Paint and its all new again. Braking is real good now and coupled with new beefier Goodyear Tripletread tires is smooth. I am also in agreement about the stickier higher quality speed rated tires to improve braking especially when i drive my Modded LX. Danny.

Re: Anyone change brakes and rotors yet? Any DIYs or tips??

I am very disapointed with the brake rotors that came on my 2014 Grand Cheokee Ltd 4x4.
The hub portion which is clearly visible on the rotors with the premium 20" tires was silver color 6 months ago but nos theyshow a ring of rust. This ruins the look of the car and I don't know what to do about it. one person suggested that I have the rotors removed, wire brushed, then painted with black BBQ grill paint to withstand the heat. This sounds like a Rube Goldberg fix to me. Are others having this problem and what are you doing about it?

Caliper paint would be your best bet. G2 or Duplicolor have kits that have been proven to last.

Re: Anyone change brakes and rotors yet? Any DIYs or tips??

Thanks for the TIP. Now I need some one to do the work as I am too old to be removing wheels, jacking up the car, and getting on my knees. Since I live in the boonies, a dust free enviornment is hard to find. I may need to have a body shop do the job. Apparently the mixing products cause all wheels to be done at once with the 3 coats applied every 15 minutes which allows about 4 minutes per wheel as the pot life is no more than 2 hours. All prep work has to be completed before mixing and taping etc has to be planned for so this looks like a half day job.

Re: Anyone change brakes and rotors yet? Any DIYs or tips??

Same recommendation here. Don,t worry about dust as the paint dries by the time you can go around the rotor. Get an artists brush as the ones in the kit are not very good. Silver or black is good for the rotor. Calipers on my Jeep were done in Mopar Blue (or close too). I'll post up a pic of what the black looks like when i can get on my computer. Danny
