This has been happening every since I got the car and I was just curious about it. Eventually I will replace the part. But say I go up to 70 mph if I brake the car starts to shake. I would say more on the driver side. The only suspension work I have done is changing the sway bar for a solid one, and replacing the passenger side wheel hub with a timken. So I was wondering what could that be

 

If it's only while braking, it's probably a slight warp in the rotor

 

Yea I agree 100% Chibi thats what it sounds like to me 2 ,get your break rotors balanced

 

I second and third that. Get them cut or just replace them.

 

I agree with Chibi as Well, If it only happens when you apply the brakes, It's a warped rotor! But If the rotor is warped you should feel it no matter what speed you apply the brakes, maybe not as harsh though.
It could be, though less likely a tire Balance issue, a bubble in the tire, there is even a chance that the bearing you put in was defective. I say, get your rotor cut and put new pads in. That would be the least expensive thing to do. Then If that doesn't work, check out the other things.

 

I have to agree with everybody. I just bought new ones, I'll eventually get the others cut for back ups.

 

get some rotors and should fix it....like everyone else said haha

 

There are several possibilities that will causes shaking.

Excessive rotor lateral runout
Loose/worn suspension parts
Bad CV joint
Loose brake caliper
Defective brake caliper
Misalignment of suspension
Contaminated brake pads

I think I would start with a front end inspection so you can narrow down the possibilities.

 

My vote is a rotor as well.

 

At first I was also thinking rotor but I don't feel pulsing at the pedal and also it n only does it when braking from high speed. Like normal stop and go you won't feel it. This morning I was on my way to work and decided to keep the radio off. Kind of heard what seemed to be a slight popping sound when I was braking. Shoukd of recorded audio
