I am needing new pads and rotors...what brands are you guys going with?
I have a 99, and i was told that I can put either cast or composite rotors on, whats the pros and cons to each?

 

I used EBC drilled and slotted on my 98.

 

I guess im just confused between the composite and cast part...is there any benefit between the 2?

 

Composites are lighter. Cast are cheaper.

 

Just did my pads and rotors on my 98. Bought the stuff at a local NJ supplier down the street. He gave me Bendix MRD477 pads and off brand chinese rotors: Best Brakes GP53035. $60.00 for everything. Look at my pics gallery to see how the job went.

 

You can run into fitment issues. One (I can not remember which) uses different size wheel studs. If you put the wrong one on, you are gonna have the rotors binding up on you. There was another thread on this forum that will explain it better.

 

I called the dealer and they said that they are the same thickness and carry almost the same part number and and for the most part are interchangeable...they could be wrong though. I have a 99 so they changed it halfway through the year so it's almost impossible to know what my jeep originally came with

 

It is not the thickness it has to do with the backspacing. Or how tall the hat portion is if that makes any sense.

 

If you take a composite rotor and a cast rotor and lay them down flat next to each other you will find one rotor is taller than the other. Pull the old rotor off and bring it with you when you go to the parts store. There you will see the difference.

 

They can tell you all about your Jeep if you give them your Vin #.

 

"almost the same part number"??? Part numbers have to exactly the same for it to be the same part. It sounds like you should find another Jeep dealer to buy parts from.

There is a difference in "hat height" between the cast and composite design rotors. Using the wrong style can cause the rotor to hit the steering knuckle and keep the wheel from rotating. As mentioned above, bringing an old rotor to the store to match up is very good advice. It could save you a second parts run.

 

I guess that I worded that wrong. The interchange part number for the 2 was the same. I wasn't going to buy from them in the first place. Dealer prices suck. I didn't have the vin with me when I called so the guy said he couldn't be 100% certain. I'll probably just do that and take it in. I don't mind making trips though the store is like a 2 minute drive lol
