Ok lately i have been noticing that when i apply my brakes that the front of my car kinda shakes, mostly on the steering wheel. I recently had EBC greenstuff pads put on about 20,000 miles ago on the front... i broke them in fine but now i am starting to feel the steering wheel shake when i apply them hard and then when i am almost stopped my brakes sometimes sqeak. what do you think could be wrong?

Like i said the only mod i have on brakes is the brake pads, i still have oem rotors

when the steering wheel shakes you usually have warped rotors

ditch the pads. Everyone on here who's bought them seems to have the same issue. Talk to robbclark about it. He swapped the pads w/o even resurfacing the rotors and the problem stopped.

so wait if swerving when braking is a sign of warped rotors then i may have warped rotors, i mean my car has like 28k on it so is that normal ? or im unsure, if they do need to be replaced, what would be a good upgrade?

to the possibilty of warped rotors is it worth upgrading the rotors and pads to something else like brembo blanks and maybe some hawk pads or something like htat? or just stay oem?

whoa.. first time ive heard negative comments about ebc's..

here in the phil.. they got a pretty good rep going for them..

okay rob, i want just some good pads for street use, not track, on axxis which ones do you prefer? i got 17 inch wheels as well.
i am glad that its not my rotors

the AEM's do it too, im having the same problem!

i hope my rotors are warped- they are powerslot slotted rotors...

I just odered some PBR metalmaster pads...hope the problem goes away!

should i just go back to stock and say fvck it?

First thing to do, would be to take the rotors in to <Insert Favorite Car Shop> and get the rotors shaved... I never buy the upgrade brake pad *COUGH* I'M POOR *COUGH*

But when you Pads wear in a certain pattern on your rotors, so when you swap the pad with out the rotors, you will 90% wear you Rotors down unevenly. Sometimes it's not to bad, you can just shave em.

It's like wearing your favorite shoes for a year... then your brother with the same shoe size tries em on and they just feel right... *Plus there stinky*

I have not had a single problem swapping my pads without resurfacing my rotors. They brake hard and barely shake. Just get the ultimates or metalmasters.

stock rotors tend to warp a lot i warped mines at 11k yes ur rotors are warped and that makes the pad wear unevenly and u loose brake performance. get new rotors (brembo, powerslot, rotora... no ebay ones )and if ur pads are pretty new get them resurfaced so they have a nice fit on the new rotors

hate to say this but the brake pads them self wont cause the shake that your feeling its cause from the rotors being warped/thickness variation

 
Rep Power: 412

Have you not read anything I said? It is the pads. I had them. They do cause shaking, especially when slowing down from high speeds or when they are cold or it is humid. Ask Taz too or anyone else who has the EBC pads. I put on a new set of pads without resurfacing my rotors and have not had a single problem and no vibration when braking.

 
Rep Power: 309

I read everything you said, and I still don't get it. Ok you don't like/Had bad experience with the Green Stuff Pads. Granted they may be crap, I dunno, Never will know.

But I do not see how it is physically possible for the brake PADS to shake the car. The two pads are stationary, there is a huge rotating disc inbetween the two. I'm sure no one needs the basics of Brake functions explained to them. But if the cheap pads wear unevenly, or malfunction in anyway, the only effect will be grinding on the rotors, which in turn will warp the rotors. It is an extremely different effect to have warped pads/perfect rotars or to have perfect pads/warped rotors. Either case will warped part will damage the perfect part, but when the rotor becomes uneven, it is the rotating mass that causes the car to shake, Because the caliper is stationary w/ respect to the car, and it only applys forces in a manner perpendicular with the car, it is physically impossible for it to cuase a shaking or vibration in an up and down motion.

Another thing I don't get. You say you've changed your pads without changing/shaving your rotors. Are you driving a 7th gen civic or the car in your avatar? (too lazy to look up your bio) Cuase if you've had to changed your brake pads more than once, and your still on stock rotars something is wrong.

I totaly agree, BUT have given up on going there!

ok, the pads are not friendly to rotors, plain and simple. Their compound is not well liked on a 7thgen. You pick up a pair, put them on your car, and you will see. Regardless of what you think about warping rotors, the pads did affect the shaking without warping (or at least not severely) my rotors. Yes I drive a 7thgen, and yes it is a problem with EBC pads and 7thgens. Again, ask anyone here who has bought EBC Greens and they will say the same thing. Now unless the rotors were warped and the pads fixed them (which I highly doubt) I attribute the reducing of shaking to the pads. I swapped out the pads and the shaking went away. I could not get my rotors resurfaced at the time so there goes the warped rotor theory out of the window. I have experienced the EBC pads and just swapped the pads so I know what caused the difference. I even sanded down the pads and the rotors lightly to see if that would help and it didn't. I drove with the EBCs in autox and I drove with the Axxis in autox and it is like night and day. There is no shaking with the Axxis. NONE! You can disagree with me all you want, but I have experienced it regardless of the warped rotor theory. You are failing to incorporate pad compound and heat dissapation when braking.

I'm definatly not argueing the point that EBV or whatever pads are anygood or not... I buy the Cheap pads for every car I own. What I'm saying is that I don't see how it is a physical possiblity that Bad EFB or whatever Pads can vibrate a car. I could be wrong (Don't quote me on that) I'm not a Mechanical Engineer, I went Civil. But I've had all the Statics, Dynamics, and up to Physics III and as far as I've learned about forces it's impossible for pads to cause vibrations. The rotors will cause vibrations not the pads. What do you mean Pad compound?? I also don't see how heat dissapation would affect anything. I think you mean when the heat raises (elevates) not dissapates, when the heat dissapates the pad is not even touching the rotor. A raise in heat cuases the metals to expand, creating a stronger connection between the rotor and the pad, but this shouldn't cuase any forces on the car in a vertical direction.

REGARDLESS.......
Vibration when breaking is the rotors (95% of the times)
There I gave you 5%
So shaving the rotors is not bad advice.

And most importantly my old sneaker analogy still fits.

I know shaving the rotors would have been good, but I couldn't get them done that day and I needed the car. Again, I am not saying you don't know your **** about physics, but I am just telling you about my experience. The compound of the EBCs for some reason doesn't agree with the car. I can send them to you and you can test them out if you want

... Its actually Extreamly hard to warp rotors.... Most of the time its just pad material build up that makes the rotor feel like its warped...

 
Rep Power: 304

^^^
do stock pads build up material on stock rotors?

edit: how do you clean it up? just some break cleaner?

 
Rep Power: 328

Yes, and usually the pulsation that most people feel isnt from warped per say, but more from unparrallellism (sp) in the rotor. But this is caused from warped rotors
