The contact owns a 1999 Jeep Grand Cherokee. While driving 55 mph under normal driving conditions the driver attempted to slow down. The front of the vehicle and the steering wheel began shaking. The shaking stopped when the vehicle speed was reduced to 45 mph. The vehicle has not been looked at by a mechanic but the contact believes the brake calipers produce too much heat and cause rotors to warp. The current and failure mileage were 71800.

1999 Jeep Grand Cherokee shakes violently when brakes are applied. On 13 Nov 02 brake assembly was replaced by Chrysler under tsb 05-003-02 front brake pulsation during light to moderate brake application all 1999-2002 Grand Cherokee wj models built through May 10, 2002 came equipped with brake calipers made by teves. Due to poor caliper centering, the teves calipers caused the rotors to warp, a problem that has plagued Grand Cherokee. The dealer put on the same defective part listed above I.e teves calipers. The Jeep Grand Cherokee continues to shake violently when brakes are applied, due to a defective part.
0500302B - front brake pulsation during light to moderate brake application date: 12/16/02 (supersedes 0500302A dated June 10, 2002) model year(s): 1999-2002 (wj models built on or after May 11, 2002; wg export models built on or after August 16, 2002). Description: Brake roughness or pedal pulsation when the brakes are applied. The customer may experience a vibration of the steering wheel, floor, seat, instrument panel, or a minor pedal pulsation (brake roughness) under light to moderate pedal application. The condition may be caused by excessive thickness variation of the brake rotor surface. Details: This bulletin involves the replacement of both front brake rotors and caliper assemblies. Note: New brake rotors must be used with the new brake calipers. Diagnosis: 1. determine if the front brake vibration/pulsation is caused by excessive thickness variation of either front brake rotor. 2. if excessive thickness variation of the front brake rotor is at fault perform the repair procedure. 3. if this bulletin has already been performed, and front brake pulsation/vibration is present, do not perform the repair procedure. Investigate other possible cases for front brake pulsation/vibration.
: the contact stated at 40 mph, the vehicle wobbled and the brakes pulsated while pressure was applied to the pedal. Also, the ABS light illuminated intermittently. The dealer replaced the front rotors, calipers and pads, which corrected the problem for a short time. The vehicle has been to the dealer for this problem several times to have the rotors turned or replaced. The average time between failures is about 6000 miles. In 2004 the contact took the vehicle to another dealer who replaced the rotors. Again, the problem has reoccurred and the dealer determined that both the front and rear rotors needed to be replaced.
: the contact stated while braking at any speed, the steering wheel shakes. The dealership replaced the rotors four times, but this has not fixed the problem. The vehicle was taken to an independent repair shop that determined the calipers need to be replaced. When shaking occurs the vehicle seems to have less stopping power. A driver unaccustomed to wheel shaking when braking could lose control of the vehicle. Contact has already replaced six sets of rotors. There seems to be inherent flaw in the original brake design. The contact felt the dealer did his best to try to correct the problem.

1999 defective Chrysler grand Jeep Cherokee.** answer required***. the consumer experienced repeated problems with the rotors, pads and calipers. The consumer has experienced hard vibration not only in the front end of the vehicle, but the steering wheel, floor, seat and instrument panel. The vibration was so severe the consumer would lose control of the steering wheel. The rotors would heat up, the caliper froze. The intermediate shaft was replaced, the rear latch was lubricated due to squeaking. The battery was replaced because the consumer had a hard time starting the vehicle.
The brake rotors and pads keep wearing out, and the vehicle makes a chatter noise and vibrates when the brakes are applied. The consumer took the vehicle to the dealership and the brakes were replaced six times. The problem started on August 21, 2000. The replace brakes wore out at six to seven thousand miles. The dealership replaced the front rotors, the pads, the front calipers, installed a technical service bulletin ( tsb) kit, resurfaced the front rotors, rear brakes pads, and rear rotors; each of these have been done multiply times. There have been no accidents as of yet.
I purchased this Jeep used with around 25K miles on it. After bout 1 year of driving my rotors started to vibrate when brake applied. After a couple days of this my drivers side brake caliper locked up while my family and I were out for a ride. I pulled over to see my rotor glowing red, I left the vehicle parked there over night replaced rotor, pads, and a new caliper. Within 2 months same thing occurred with the passenger side, so I fixed that side. Since the original problem I've replaced both rotors 3 times and pads 4 times in less than 8 months. Dealer says there is nothing wrong with brake system, I disagree. After researching this on the internet I see that a lot of owners have the exact same problem. I can not see how a manufacturer can get away with these kind of problems. I know that if the company I work for had built and sold faulty products we would be sued and out of business. Why is this company allowed to get away with these obvious malfunctions of one of the key components in safety on a car, the brakes. Thanks for any and all help.
Had front brakes serviced May 2003 new rotors, pads. August 2004 had to have new calipers, pads and rotors resurfised. Because calipers failed and almost started tire on fire. Told there is a service bulliten ref putting on different calipers.
Dealer replaced at 11,000 miles the front rotors and pads. At 16,000 miles, the front rotors and pads were replaced. At 35,000 miles the rotors were resurfaced and the pads were replaced. At 45, 000 miles the dealership indicated they needed to replace the calipers, and install a bigger caliper. The warping front rotors caused pulsating brake pedal and an uncontrollable steering wheel.
Continued problem with significant front brakes pulsation during light to moderate braking. At times, steering wheel vibrates violently. Learned of how common the problem was from this web site within a year after purchasing vehicle new in 1998. Kept hoping for Jeep to step up and accept responsibility. Nursed original parts to 68K miles waiting for Jeep to come up with better solution than frequent replacment of rotors. Finally, in 2002, new service bulletin called for replacing calipers with new design. New caliper and rotors installed Nov 2002, 20K miles later, problem returned. Spoke to local service managers, no solution. Spoke with Jeep corporate hq, no solution.
The rollover valve gas tank and fuel pump leaked. Also, consumer complained of brake problems, such as caliper replacement every 6 months. In addition, ignition malfunctioned. Consumer attempted to start the vehicle at least 3 times before it actually started.
1999 Jeep Grand Cherokee front calipers warped 4 times in 3 months, upgraded to diamler Chrysler modified calipers, problem persists. Resulted in an inferior braking condition which turned the car into a road hazard several times. Diamler Chrysler has not issued a recall to date.
1999 Jeep grand chereokee, front disc brakes keep going out. Rotors goes out of round, about every 15000 miles, due to poor rotor and caliper design. Jeep (and dealers) know this is a problem because there is tsb regarding the issue with the fix being new rotors and calipers of a different design, but they won't do anything to fix it, without costing $500+ to the consumer. Accident waiting to happen.
When driving over 55 mph vehicle vibrated when the brake pedal was pressed. Dealer tried on five different occasions to fix the problem. The calipers/rotors, and pads were replaced, some more than once.
My 1999 Jeep grand chrerokee has a significant brake system problem requiring turning of the rotors at approximately 9,000 miles and replacement of the brakes and rotors at approximately 19,000, 36,000, and 51,000 miles(approximate mileages based on memory but I can provide detailed service records if needed) each time replacement was required to eliminate a severe vibration (which felt like I was driving over rough railroad tracks) when the brake pedal was depressed. All installments prior to the one at 51,000 miles have been at the Jeep dealer. Each time, when I questioned why such frequent replacement was needed, I was told "it's a wear and tear item". the most recent rotor change (at 51,000 miles) was performed by an experienced person at an independent garage. He told me that the problem appears to him to be a design flaw resulting in misalignment of the brake calipers, rotors and brake pads such that one of the two brake pistons brakes is striking its target slightly off-center. Continuous misalignment of the brake pistons appears to be causing the rotors and brake pads to wear unevenly resulting in development of the vibration. So replacing the rotors and brake pads fixed the problem for now but is only a temporary solution. With new rotors and brake pads, the vehicle is braking fine but I anticipate that by 60,000 - 65,000 miles the problem will occur again. You have several tsb's on your website reporting "vibrations" when the brake pedal on this model vehicle is depressed but none of the tsb's elaborate on the cause of the problem. I have contacted Chrysler directly multiple times and keep getting put off with "it's a wear and tear item". now that I have been alerted to the possiblity that there appears to be a brake design flaw I think that they are just ignoring a problem that should probably be a recall. I am not aware of any safety issues. Thank you for looking into this problem.
1999 Jeep Cherokee. Warped and continous problems with rotors and calipers. Problem continues shortly after having them fixed repeatedly. The pulsations at high speeds(55mph) are violent.saw the same/similar complaints by many others. Dealer says Chrysler not responsible. How many times can you afford to fix the same problem? something that has no remedy must be a design fault.
Within four years approximately 8,000-10,000 miles both front brake rotors had to be turned twice and then replaced. Also, both front calipers had to be replaced. This causes vehicle to vibrate and make a grinding noise when braking. Dealer and manufacturer were notified, and were unable to locate the cause. The brakes pulsated while driving. The dash vent did not work, and the air only worked through the defrost. The consumer stated the front end of the vehicle felt loose, the dealer discovered the ball joints needed to be replaced. The driver side rear quarter panel was loose
