First and formost, i searched the first 5 or 6 pages of "brake vibration" with the infamous search button. Came up empty handed...
Sooooo, so today i put my 17's back on for the summer and took my car out for a spin. Everything was fine until i got to a light and had to slow down. Right before i came to a stop ~5-10mph to 0mph the brake pedal vibrates. The only thing i can think that is wrong is that i need an alignment. however, wouldn't an incorrect alignment also cause the steering wheel to vibrate, not the brake pedal? Any suggestions/ideas would be greatly appreciated before i spend money on wasted time/service. Thanks a lot.

My guess would be warped rotors. If this is consistent at low speed lite braking them consider getting your rotors re-ground or purchase a new set.

To my knowledge, stock Honda rotors use a pretty shotty metal with a very low carbon compound. So replacing them wouldn't be a bad idea anyways.

If it only happens when you put on the brakes it is most likely rotors, not alignment.

well, the thing is i just replaced the rotors about a month ago and everything was fine with my "winter wheels". As soon as i put my "summer" wheels on this started happening? thanks for the responses though. any other ideas?

edit: oh yah, and it only happens when i brake only under 10mph. not all the time

Could be that you over tightened the lugs when installing your summer wheels and warped the rotors. I have seen that before, but usually only when somebody uses an air wrench and really hammers it. Just a guess.

yeah, i used a torque wrench on all the lug nuts 80ft/lbs. so i don't think that is it. i've got free alignments for a year so i guess i'll go get one of those to see if it does anything. any other ideas would be great, thanks for the help though.
also, is it ok if i drive around like this, no serious trouble right?

your wheels probably need balancing

^^^ not the balancing. when the tires are out of balance it usually shakes at higher speeds, 50+. Also he said that he can feel it through the brake pedal not the steering wheel, another indication that it has nothing to do with the balance. Laslty it only happens when he is braking, that pretty much eliminates the tires from the problem and point the finger at the brakes.

^^^ yeah thats what doesn't make sense, yesterday morning with my winter wheels, braking was perfect, then i put the summer wheels on and now the pedal vibrates 10mph and under. i don't know what went wrong? the only things that were changed were the wheels.

I've recently had a similar problem... I believe it has something to do with either the ABS kicking in slightly because one of the brakes are off a bit or messed up rims all together... I recently curbed it while passing through a narrow tunnel... I can feel the steering wheel shaking on perfectly flat roads when slowing down to a stop.

I would like to know what the answer is to this also...

You live in salt on the roads country in the winter yes ? Was there a LOT of corrosion on the hub where the wheel mounts? Did you inspect your rear brakes at that time too(pull drums off) ? Or for any reason pull the rotors off? Do you know the difference between a brake pulsation and an ABS pulsation?

and to clear up wheel alignmnet possibility its not possible for the alignment to cause any kind of brake pulsation and or steering vibration. Vibrations are caused by rotating parts ONLY!

^^good points. i did notice some rust on the hubs when i took the wheels off. do you think that could be the problem. i mean, the brakes ONLY vibrate at really low speeds.

man, this guy is on the ball

its a possibility, not saying it is the problem but ive seen it before

hey tfnaaf, it's ok for me to drive a day before i clean that ish up right?

 
Rep Power: 328

Like i said that may or may not be the problem, did you pull the drums off when you did the wheel switch ?

 
Rep Power: 328

im just trying to think of possibilities

 
Rep Power: 0

pull the drums off? no, just the wheels. i removed the winter wheels, then my summer wheels use a spacer so i put that on where the wheel mounts, and then put on the summer wheels. 80ft/lbs. there was some rust where the wheels and spacers mount, but i did not think it was a big deal. i'm going to clean that off tommorow night. the vibration isn't horrible, would it be ok to drive though? thanks for your help man.

 
Rep Power: 328

Not seeing or being able to drive i cant say for sure. But typical pulsations on brake apply are not an immediate safety concern

ok, thanks again.

ok, well after paying some very close attention to the problem at hand i discovered some different things. the actual vibration only happens between 22 and 18mph. it not only vibrates the brake pedal upon braking, but also a little bit on the clutch pedal (when it is depressed). so now this is totally boggling my mind. i have no idea why this is going on.

any ideas?

Nope

If possible put your winters back on just to try it again. That way you can see if it is the wheels or something in the brakes that happened when you did the switch.

^^good idea, i can't believe i didn't think of that. thanks
