Hey guys. My car shakes when I apply the brake. Worse at high speeds. There is a loud pulsation and vibration.

I changed the front rotors, pads, upper control arm ,bushings.

Funny thing is, when its rainy and wet (after wash) it doesn't do it as much until its dry again.

Could it be the rear brakes? Tie rods?

Any help would be AWESOME!!!!
Thanks guys!

 

did you lower your car or get new rims?

 

Hmmm. I had it aligned too, but wasnt the greatest alignment.

It only shakes and vibrates VERY loud when I hit the brakes.

Maybe I will try to get it aligned again.

 

No. Im gonna do those after I figure this prob out.

 

What do you guys make of it that the shaking/vibration goes almost away when it gets wet?

Possibly the rear rotors? The noise seems to be coming from the front right.

 

You need to make sure the caliper guide pins are lubed and the caliper slides freely on those pins.

Good luck...

 

If you feel the shakes in the steering wheel when you brake, it's the front. If you feel the shakes in your seat, it's the rear.

 

Not really the steering wheel. More like the Pedal pounding and shaking in the front when I brake.

 

i had the same issue when i had stock brakes and it was a combination of the guide pins as well as the rotors. i think it may be the rotors. if you've ever slammed on the brakes at one point they may have warped or obtained uneven wear. so when you brake, especially under a large load or downhill the car will vibrate every time your caliper runs over that groove in the rotor. might be time to resurface them or replace them too?

 

I thought it was the rotors so I changed pads and rotors today.

 

and the outcome? also how long has it been since you checked your brake fluid? super dirty? leaking anywhere?

 

Did that help?

 

Same shaking. Fluid looked fine and no leaks.

 

hmmmm, wow maybe time to bleed the brakes could be bubbles in the lines?

 

OK thanks man.

Do you think that would stop the violent vibration?

I thought this might be a calliper problem but I'm not sure.

I guess it has to be some kind of brake system problem right? It only
happens when I press the brake. Gets worse the faster I'm going and hit the brakes.
