Post subject:  Disc Brake Pad Set Longevity........
Last night I performed an oil & filter change, drained the fuel filter, and tire rotation on the ol' CRD. It's at 58,437 miles.

I'd estimate the front brakes to maybe be at 50% to 60% worn (and evenly) and the rear brakes to be around 70% worn (the inner pad on the right rear wheel seemed to be wearing a little more at the top than the bottom).

My wife is the primary driver....hats off to her good driving habits and for not running up someone's arse then applying the brakes.

Anyone else get this great of service out of OEM friction material ? Mine have been as quiet as a mouse peeing on cotton (no squeals/squeaks/grinds/etc) since new......it's a no brainer that I'll go back with OEM brake pads when the time comes.

What kind of service life have other CRD owners gotten out of OEM brakes ?

I find it strang that your rear brakes are wearing more than the front. I am at 48000 miles now, but had the sqeaky rears replaced ay 10K miles. The front are about half worn. Rears look almost new.

that's been the norm for people on this board at least.

As heavy as this thing is, and with most of the braking power being delivered to the front pads, why would the rears wear faster....unless the calliper slides are sticking?

Post subject:  ESC kills the brakes on US '06 KJs
I started using my Full Time 4WD more often after wearing out the rear pads on my 06.
When I figured how the ECS works, by applying the rear brakes.
I can't speak for 05 KJs.
Was ESC an option on 05?
Another benefit of using the Full Time 4WD is being able to blow away big block Tahoes and H2 Hummers at stop lights when the pavement is wet.

I believe thats what some of the more knowledgeable guys think. I know I replaced my fronts at about 38k I think, and the rears around 50k. That surprised me as most of my rear brakes i've done on other cars I replace at 80-100k

Maybe it's like warp said. The esp is firing to keep control of the thing, and that wears them out. Course, you have to been in situations that trigger the esp to fire. I have only heard mine fire up once, and it saved my bacon from a spin on a narrow, icy canyon road. Maybe in the summertime, for highway useage, turn it off to save brakes, at least on dry pavement.

From what I observe, my 06 has traction control built into the ECS. MrMopar may have access to documentation to endorse or shoot down this observation. I have had the ESC light come on when I spun the rear wheels, now I use Full Time 4WD every time I think I can spin the wheels and Part Time when the others are on their cell phones calling a tow truck.

I can not remember how many times I have had to turn off traction control to get unstuck in rental cars. I guess using Full Time 4WD does it for me.

Truth is the best way to defeat idiots, even electronic ones like ESP.


BTW: I just sent off my report on how I had to out smart a "SMART" VFD drive that kept tripping out on overload.

I guess I will save the ESP for the unforeseen incident on dry pavement.
Never know a meteorite may go through the roof and bump me on the head when I drive at night. :lol: :lol: :lol: :lol:
I had one piece of aircraft junk hit my drivers door pillar when I was coming back from MDW.

I replaced the rears at 42k I think it was and they still had meat on them. I am replacing the fronts at around 61k with meat still on them but I have the time to do it now.

A lot of Stop n Go traffic...front brakes gone at ~40,000...rears at ~55,000

I do think spirited driving that activates ESP does affect brake longevity.

I am sure also, why mine lasted as long as they did I don't know why, lol.

I can't imagine that the ESP would activate enough to have any measurable effect on pad wear. Even driving hard, the driver-induced usage of the brakes is likely going to be by far the largest consumer of the friction material. When the ESP fires, the pulses are very brief.

ESP makes a massive dent on brake pad life.Replaced brakes on a '07 JK yesterday that does get wheeled also and all the 4 corners had different pad thickness left.This was a Sahara version without any lockers.Both inner/outer pads on each wheel where about the same but the L/R was about 2/32" left while the R/R had about 7/32" left,calipers are not sticking either,same went for the front.

I have 70K on my CRD and the brakes are 50% front and rear. I was traveling on I90 in Kimbell, SD towing a fully loaded 3,000 v-nose trailer when I drove into black ice with freezing rain at 75 MPH. To make things worse, the tires were down to the wear bars as the wife demanded that I make another round trip before replacing them. I slid for a mile but the ESP kept me on the road. I should of went into the ditch like many other cars and trucks including 18 wheelers that did. I have new tires now and my wife have new panties. :lol:

I noticed significant wear at 30-40K, but now i'm at 76K now and the pads are still hanging in there. besides some wavy rotor wear there are no bad symptoms, or squeaks. this summer i'll toss on new bendix rotors, pads and maybe sliders if they are rusty.

for my info how are you guys compressing the caliper? with the bleeder screw open or closed? any special procedure?

i'm really impressed by the durability of this car ('06). no rust at all, always starts, never stranded, very infrequent part failures, maintenance is easy and cheap, its easy to fix body damage, and it gets good MPGs. by the time this jeep wears out, i'll probably be replacing it with either a full eletric car or one powered with cold fusion that also flies.

Agreed, wheeling would be a different story.

I replace mine front and rear at 36k and at 60k miles, then my clock spring broke. now that the ESP doesn't work the brakes are wearing like normal brakes on any other car and i couldn't be happier. so yes the ESP does wear away at the breaks even on dry pavement.

Post subject:  More torque = more wheel slippage and ESP Brake wear
That is the nature of our CRDs. When ever the road is just a little slick from rain on top of oil leaked onto the intersection, mud washing over the road, ice, or Snow, the rear wheels will slip under moderate acceleration.
Now here is my big Big Block Tahoe at the stop light beating secrete: I put it in Full Time 4WD and put all the torque the mule can put to all 4 wheels. I shoot through the intersection while the Big Block Tahoe is trying to get a grip on the stall speed of the torque converter and the pavement with only the rear wheels. A Dodge powered Cummins, Chevy Duramax, or even a Ford Powerstroke could do the same, torque out of the hole wins.
Now what does this do to the rear brakes in 2WD, wear them out faster.
After all I only humiliate the Tahoe and never put it or its occupants in any danger.
