1993 Grand Cherokee disc brakes keep warping and squeking

[wpatters1229]

I keep having to have the disc brake rotors turned to get rid of the wobble. I bought the best brake pads and they squek like crazy. Applied backing glue, etc.. nothing helps. Are there any over size/beefier rotors that can be bought to replace the factory ones? I don't brake hard. This really becomes noticable when coming down a mountain road and you have to apply the brakes a lot. They start shaking.

I am having this same problem right now. In fact, I was just checking the post before my way out to get it turned for the second time since I bought the best Raybestos brand and dustless/ceramic pads last May. Last time I had it turned was in October. Must be my wife doing all the hard braking........

I have the same problem, 95 ZJ. Apparently 93-95 have a history of warped rotors. Had to change my front pass. side just this last weekent, went cheap due to economics. When able, plan to upgrade to slotted rotors, they displace heat and brake dust better. Have seen them $48. to $90 on the net. If anyone has gone that route, maybe some suggestions as to brand.

Check the factory updates at your local jeep dealer...They had a call back on the 93 GC for
bad front rotors.

I went out and bought Raybestos slotted rotors and ceramic pads for the front brakes on my 93. What a difference...no shutter when braking, no more dust, no squeak. At first they seemed not to brake as good but I was taking it easy. I broke them in by doing a series of hard to soft braking and used the e-brake to hold the jeep at a stop light so the brakes could cool. After a few days of doing that I had an emergency and had to rush my grand son to the hospital with an anzyema attack. I had the flashers on and was doing some serious high speed driving and hard!!! Braking. We got there in time and after I settled down I remembered the new brakes. No damage and I'll tell ya when you really come down hard they got better as they got used harder. Like night and day.
I wanted to get slotted and drilled but because the rotors are not cast they only recommended slotted. They work great. I'll be going to Yosemite next week and will give them a great test coming out of the mountains.

Upgraded brakes, rotors, calipers etc... are definitely the way to go.

The front rotors on these Jeeps don't have much metal in them so they heat up fast. so when you turn them down to make them run true again, you end up with a rotor that has less metal in one part than another.So when you put your new pads in they work fine for awhile then your back to where you were again,warped rotors, this is because of the differnt amounts of steel heating and cooling at differnt rates. Jeep put on cheap pads from the factory. great for braking, bad on rotors. My 98 ZJ had the same problem till I replaced the rotors with the cheapest rotors I could find, then I used ceramic pads, ceramics will disapate heat fast. The dealer did two brake jobs to the front of it with less than 30,000 miles on it. I've put over 80,000 miles with half the pad to go.The back rotors I replaced because of rust, the backs rarely warp as they are the single disk instead of the double on the front. Hope this helps

Talk to Dale, or get custom brakes is my opinion

Ok but what brand works well? I need to doours, and my sisters. We would like to upgrade tha lousy brakes, but what brand? And should I do drilled, or slotted rotors?

[Dsilver]

Well Im not sure who makes brakes for Jeeps, but Brembo, Baer, Stoptech etc... just search on Google, your sure to come across something that fits a Jeep.

But with installation and parts, it could be $2000 per vehicle, its not a cheap upgrade.

[wpatters1229]

Here is what I did and it is still working just great after several months. The first time you stop when they are cold they don't work too good. They actually get better the harder you stop. The setup costs about $300 and installing them is really easy if you have a few wrenches and are not afraid to go for it. Always do one at a time so you have the other one to look at. Even the pros do that. You can't remember all the cars they work on.

Ok i have the same problem.

I have plenty of life left on my brake pads.

First will turning the rotors help this?
or do i need to buy new rotors?
if i buy new rotors do i have to replace my pads or are they ok?

Thanks

Turning the rotors will stop the vibration but it also removes metal and that will allow the rotors to warp more easily as they won't absorb the heat.

if you can, put the money you woud spend on turning towards the new rotors.

If The old rotors arn't scored or worn unevenly, you may get away with using the old pads again. Old pads from scored rotors will reduce braking ability and increase heat with the new rotors and that increases the chance of warping the new ones again.

Check the caliper slides to make sure they are free moving and torque the wheel nuts evenly, to 90 ftlb. Both will contribute to rotor warping.

Best bet is to start with all new. Anything less will not give best possible results. Brakes are nothing to be cheap about. Think of the alternatives!! Scary.
