in Canada we use Kilometers eh!

 

Both systems are European. Only one of our countries hangs onto one particular system like they invented it and like it means anything that they do so.

I won't mention which country but their flag uses the colours of both England and France

Oh - and they get really testy when you point out that the 'white house' used to be called the 'president's mansion' before we torched it and they white-washed it to make it look like we didn't.

 

My other half used to have a Jeep Liberty. 90,000 on the rig and brakes were never replaced. To this day, I'm amazed. I go through brakes historically at a fast pace but she seems to get every last drop out of them. Jeep OE brakes seem to be pretty solid out of the box from a longesvity standpoint.

 

I just had my rear brakes replaced at 47K. I had a shredded ABS sensor wire for about 6 months or so. The fronts are still good.

 

Yeah, I've read here that the "soft locker" feature of the JK's ESP/traction control system where the traction control portion applies the brakes to one (usually rear) wheel in order transfer power to the other on the same axel (kinda like a computer-controled limited slip diff) is most noticable, and effective, in mud & snow.

The ESP/ABS/traction control system has been repeatedly identified as the culprit behind the JKs rapid disc rotor and pad wear in some vehicles, particularly the rears. I've noticed that while my front disc rotors are pretty uniform, my rears have a noticable pad-groove which will require machining when I change the pads.

 

Rotors only need to be changed or turned on a lathe if they are causing the brakes to pulsate when applied. A grooves in the metal will not bother them at all. Don't let shops tell you that it has to be done everytime you change the pads.

 

Yep, agree with you there; the little shallow grooves on the disc where the pad covers will only cause a little squealing perhaps on fresh pads for a while. The groove I was referring to is a raised ridge at the outer and inner edge of the disc where the rear pads dont cover, with the area of the disc the pads cover worn deep into the rotor. Unless replacement pads are of exactly the same measurements and seated in the caliper at exactly the same angle, there would be issues without these ridges being machined off; made this mistake once on a car & wrecked the rotor & new pads. I've found that pulsating brakes often mean the disc has been machined too often and has warped from heat due to being worn too thin.
