rotors

[glennco1]

Cross drilled rotors also wear the pads faster, so take that into consideration if you are looking at them.

those are vented and crossdrilled. i just want vented, if i can find them

there's some cheaper vented, drilled, slotted ones.

Ther are slotted rotors and rotors that are slotted and cross drilled. the function of the slots and cross drilling has verry little to do with cooling.

The benefit of the slotts and cross drilling is in the release of the gasses produced when the pad material heats up to reduce brake fade at the linings.

These are available for the jeep at a COST but don't give much protection against warping and parallelism faults that cause the pedal pulsation.

Right for everyday driving, vented discs are just an added expense.

As I understand it, warping is essentially caused by stepping on the brakes too hard. This, combined with the compound used in the rotors allows the rotors to lose their shape in the location that the pads were in contact with the rotors.

[JDPascal]

Most warping of rotors is caused by uneven torquing of the wheel nuts or something that will make the surface uneven when they are tightened.

Rapid and uneven cooling will also contribute to warping as will siezed caliper mounts or pistons.

Cheap rotors may not have the same stress relief done on them as the top line rotors. Also the cheaper rotors may have casting variences, especially in the vented rotors.

I am also in need of replacing the rotors on a 01 JGC.

I was quoted $50 per rotor, not sure if that was resonable. The main issue was the pads, they were $89 a pair. That seemed high.

Does anyone have information on where to get replacements at a better price?

Yeah do it yourself for 50 bucks, lol. There are a few places that will do it for a lil cheaper but take it to your trusty mechanic.

50 bucks per rotor is not so bad, that last time i did my rotors i pair 33 apeice at my local autoparts store.

Grands are bad on brakes. I'd think twice about the cross drilled rotors. They are expensive and I've heard people complain about them cracking(especially the cheap ones). Stillen makes a pretty decent rotor but $$$.

Brakes are not the place to cut corners. The $89 pads are likely to be the ceramic/metalics. They are by far the most cost effective pad available for the type of vehicle the jgc is.

There are cheaper parts available for the brakes but............... are they worth the risk of your wellbeing both physically and financially if you cant stop adequatly(sp?_)

I saw these on e-bay a few days ago-I also need new rotors on my jeep and was considering these slotted and drilled rotors. Not so sure now after reading the posts on the advantages of them. ANyway- here is the link if any one wants to check them out-the seem well priced but its tough to tell what quality they are-any comments or concerns????

That is a reasonable price for rotors for sure.

Not having used E-bay I'm not sure what the shipping and handling charges mean. Looks like $40 but is that for the first rotor or all of them?? There is another $25 for each additional item.

I looked for a website for the company "US Rotors" and couldn't find one so that is a flag so far.

Are they someone elses brand name. I think I've seen the brand before but can't remember where.

Your right about knowing the quality.

I'm not a big fan of ebay. I guess I have too much "Missouri" in me and like to inspect what I'm buying before I pay for it.

Besides that, they probably wouldn't be a bad deal.

$40 OEM Mopar Pads

Pads are usually sold in sets (as in 4 pads) for the front or the rear. That place has resonable prices on OEM parts..

[JDPascal]

noticed they have the caliper/rotor update there too.

Hey, I have another question regarding this:

What year did they move to the 4 wheel discs? Has there been similar problems with the 4 wheel disc models?

thanks
