Front Rotor Concern, 02 WJ
Hi All,
I went down under to do my first oil change on my '02 Grand Cherokee and to
get acquainted with the underside. I noticed the inboard side of both front
brake rotors appear as if the disc pad is not contacting them completely.
There is some shine/wear around the outside, oh, 3/4 inch or so and it
diminishes to about no wear toward the hub. I sense no braking problem in
the car at all. The outboard side of both rotors is shiny/worn equally as
you'd expect.
I thought I'd ask the group what your opinion of the malady is. I will of
course be pulling the calipers in a couple days to lube the pins and such,
but it seems odd that both sides would develop a problem at the same time.
Do I have a couple bum calipers all at once?
The car has 40K miles on it now. Was about 37,500 when I got her.
As an observation, they, DC, sure placed that oil filter in a bad spot. The
filter on my 93, 4.0 liter was on the passenger side and easily changed from
above. This one is underneath and is sure easy to get a faceful of hot oil
if you're not careful.
Thanks,
D

Re: Front Rotor Concern, 02 WJ
I believe you are looking at the steel plate that's bonded to the
brake pad, the open distance is how thick it is:

the actual thickness is to take the wheel off and look through the
caliper: http://www.----------.com/dana25knuckle.jpg

Re: Front Rotor Concern, 02 WJ
Hi Bill,
No, no the actual brake rotor/disc itself is what I'm talking about. It
shows little or no wear. Mine is not evenly shiny where the pad contacts it
as the one is in the picture you sent.
Thanks.

Re: Front Rotor Concern, 02 WJ
Sure sounds like the caliper is sticking. It may have caused the other side
to overheat, glaze and/or perhaps warped the rotor.
Do you know if you have the Teves (early '02 black) or Akebono (late '02
Silver) calipers?
Do you get pulsations or shaking during braking?
Any pulling to one side or the other?
Noisy?
You will have to pull the wheel to get a look at it, preferably pull the
caliper too to get a good look

Re: Front Rotor Concern, 02 WJ
Sure sounds like the caliper is sticking. It may have caused the other side
to overheat, glaze and/or perhaps warped the rotor.
Do you know if you have the Teves (early '02 black) or Akebono (late '02
Silver) calipers?
Do you get pulsations or shaking during braking?
Any pulling to one side or the other?
Noisy?
You will have to pull the wheel to get a look at it, preferably pull the
caliper too to get a good look
