I have 98 and 99 cherokee xj's. Both are just shy of 200k miles. Pads and Rotors have been replaced on both within the past year.

Problem - when braking, especially at highway speed, there is a great deal of vibration in the front end.

Any suggestions?

 

Warped rotor/s.

this is why its soooooo important to torque the wheels properly.

Is it vibration, or wobble? There's either gonna be a rapid pulsing you feel, or it's gonna be a true vibration? If it's pulsing a lot thru break pedal, then warped rotor, but a vib could mean somethin else

 

x3 on the rotors. A vibration caused by breaking under speed is always a breaks issue, regardless of miles. Take the wheels off and check things out.

Now, youve got this problem on BOTH Jeeps? Who did the breaks on both (and at the same exact time?), and did you use the same parts/brand? If a shop did it, Id take the one thats doing it the worst and explain the situation.
