In Need Of Help 2001 IS300
 

Hey everyone I have a problem that I just cant figure out. It's on 2001 Lexus IS300, I just put on all new rotors, pads, front calipers, and tires. When I'm driving faster than 45 mph I get a vibration in the steering wheel and when I brake it gets extremely worse. It takes a little bit for it to happen though, usually about 5 to 10 minutes of driving. When I first get going I have no problem but when everything starts heating up that's when I get the vibration. Happened right after I replaced the brakes but I went through them again and everything seems perfect. I've been to three different mechanics and they all say the brakes are great. I tell them my problem but I don't think any of them are actually heating up the components and actually feeling the problem. I just had the tires rebalanced and none of the rims are bent. Any suggestions? Bad wheel bearing? tie rod end? maybe bad rotors or caliper?
Thanks

Welcome to CL!

You may want to post this in the 1st gen IS forum, as there have been many threads in that forum about IS300 vibrations, and you may run into some other posters who have been through this.

Also, if you do an advanced search (link is in a drop down under "search" in the top middle of the page) for "vibration" in the 1st gen IS forum, you'll find lots of threads that can help you.

Good luck!

welcome, best of luck, moving to right forum.

Firstly, have you had your tires balanced?

Actually sounds like you have a sticky brake caliper - most likely caused by a restricted brake hose...

go drive the car til it happens again, pull over using the brakes as little as possible, get out and figure out which (most likely front) wheel is hotter than the other... replace that brake hose, bleed brakes, most likely good to go...
