HOW TO FIX FRONT END SHAKE WHEN BRAKING?

HOW TO FIX THE FRONT END SHAKE, WHEN BRAKING?
WHEN PRESSURE IS APPLIED TO THE BRAKE PEDAL, THE FRONT END OF THE CAR SHAKES BADLY. THE FASTER THE CAR IS GOING, THE WORSE THE SHAKES IS. REPLACED THE FRONT ROTORS, AND BRAKES, ABOUT 3 1/2 MONTHS AGO, THEY BRAKED FINE (BUT MADE A LOUD SQUEELING NOISE) UNTIL ABOUT 1 MONTH AGO, THEY STOPPED SQUEELING, AND STARTED SHAKING AGAIN. IF ANYBODY HAS ANY INFORMATION ON THIS SUBJECT, THEY WOULD BE GREATLY APPECIATED.
THANK YOU.

I had a similar problem and it ended up being my calipers weren't releasing right so I had to replace them. I would make sure your brakes are releasing 100%

Did/Do you have an Eclipse aswell, or was this on another car?. I heard that once the wobble starts, the rotors are actually warped. When you installed the new calipers on your car, did you have to put new rotors, pads, etc.. on aswell, or just calipers?. Thank you very much for the reply!.
I actually just bought a 97 RS. Mechanically they're almost exactly the same as the GS. Yea your're right. It could be the rotors. Did you check to see if your rotors are smooth or if they have any grooves etched in them? If they're smooth, you should be fine as far as rotors go. I installed just the calipers and it fixed the problem.

Alright, sounds good. I removed the front rotors and they both look smooth, so Ill check the calipers next, and maybe that will solve the issue. Its people like you that make these sites awesome!!!. Thanks again, and good luck with your RS.....
Thanks and your welcome bro. Let me know how it goes.
ok so basically since you got new rotors soo soon the shouldnt have gone bad but it sounds like your calipers are sticking which is a pretty common problem and one side of the caliper will usually stick to the rotor even after you let off the brake so itll warp your rotors especially if your doin a lot of highway driving cause it's just rubbin on your rotors so an easy upgrade you can also do if you dont already have it is get the stock 2 piston calipers from an GSX because the GS/RS/&GST are all front wheel drive and have only one piston calipers so it'll up your braking substantially and you can just get them from someone off craigslist but they are hide to find usually because everyone knows how good of an upgrade they are for the front wheel drive turbo's
Yea I agree it deff sounds like the calipers are sticking. Like I said, thats what my problem was. Front left was totally locked up and front right was dragging bad. I don't know though if I would buy used calipers. As far as brakes in general I would always get new. I paid like 80 buck for both of mine at Autozone.
I have a 2002 chrysler town and country. it is shaking when brakes are applied. The brake pads are good. What else could it be. The van was taken to Virginia and started doing that when coming back with a full load in it. What could it be anyone know.

Most locking or slow releasing calipers are caused by the rubber brake hose collapsing from inside,holding fluid under pressure inside the caliper,creating the lock up or slow releasing and dragging.
I have had to change my rubber brake lines before because the inner wall developed a flap like a one way valve, and would not let fluid backward which will keep the brakes applied all the time. by the time i figured it out i had changed rotors, pads and calipers, only to have to change the calipers and pads again half a year later. Lines are easy to change you just have to bleed the brakes. if you have to change one, go ahead and change both sides... I have heard it is good practice to also flush out old brake fluid when you put on new calipers also because the fluid has an affinity for water and will rust your calipers, which can cause them to stick.
a lot of factory cars come with ceramic pads. use regular pads and let them seat up well and you will get better results. more dust but the shaking when braking will probably stop.
