97 Cherokee Brakes Pulsating
I have been having a pulsation in the brakes of my 97 Cherokee. This
has discs up front and drums in the back. It had a recent brake job and
the front rotors are new. When my wife told me about the problem (yeah,
to add insult to injury it's her car so I hear about it alot)I drove it
to try to find it. I heard a little scraping but instead of being smart
and having her stand on the side of the road and pinpoint the sound, I
started taking stuff apart. Anyway, I tore the front and back brakes
down and put them back together, double checking everything I could
think of including making sure the torques were all right. Then I
flushed all the old brake fluid, that was looking pretty nasty. Well,
the damn sound is gone but the pulsation isn't (although I think it's
somewhat better...my wife doesn't). I'm going to borrow a micrometer
from a buddy to check the front rotors. What else can anybody recommend
that I check? Thanks in advance.

Re: 97 Cherokee Brakes Pulsating
Wheel lug nuts not torqued even or put on with an impact gun will warp
the rotor. Chrysler rotors are really bad for that. Some garages are
still too lazy to use the proper torque wrench and so they screwed your
rotors for you.
I would take it back to the shop and hope they don't notice you had it
apart or they will say too bad....
They cannot blame old rotors eh. Then when they try to BS you about
their 'cool' torque stick on the impact gun, have the bent rotor in your
hand slapping it like you want to use it up the side of his head eh.
You don't need the gauge to check the runout. Just hold a straight edge
against the rotor and rotate it, you will see the warp.
Once warped it has to be turned on a lathe to go back straight which
takes half the life off it.

Re: 97 Cherokee Brakes Pulsating
It's warped rotors again. Might tell the wife not to rest her left
foot on the brake pedal.

If the rotors are bad. There was a recall and they will replace the
rotors.
