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. God Bless America, ßill O|||||||O mailto:-------------------- http://www.----------.com/ R Sturk wrote: > > I have been having a pulsation in the brakes of my 97 Cherokee.

Re: 97 Cherokee Brakes Pulsating
If the rotors are bad. There was a recall and they will replace the
rotors. On Tue, 11 Jan 2005 23:46:08 GMT, R Sturk <sturkosaurus@nospam.com> wrote: >I have been having a pulsation in the brakes of my 97 Cherokee. This >has discs up front and drums in the back.
