these are brand new rotors that i have installed and they shake just a little maybe due to oscillation. how can i alter the install of the rotors to reduce the oscillation so it would brake in a nice and smooth motion?

thanks in advance

 

Resurface them. Some rotors come warped from the factory; especially the cheap ones.

 

Is this only shaking during hard braking?

Rotors sit against the hub and the torque of your lugnuts is what keeps them in place so there's really nothing in the way of adjustment and you can only install them one way.

Are the pads new? If you're using pads that were on when you had warped rotors, the pads could have uneven wear on them and cause a little vibration.

Other than that, wheel bearings, tire balance, stuff like that can cause vibration.

thanks, i think that is the answer. i'm doing the work on a friends' car and i'm using old pads that were used on a set of warped rotors she had on the car.

 

i agree. almost all NEW rotors are a bit off shaped. only the lazer cut rotors are perfectly straight and true. you need to resurface the rotor's and reinstall them.

madslackin is wrong. yes old pads may cause vibration but it will not cause vibrations that you can feel inside the car. the vibrations the old pads MAY cause will transalte to a high pitch squeel, i had the same **** happen to me, it was the rotors.

 

ok, i resurfaced the new rotors and purchased new honda brakepads. there is still some shaking when i brake at any speed above 40 mph.

any other suggestions?

 

make sure the calipers are bolted on tight.

make sure all the suspension components are tight.

make sure the crossmembers are tight.

basically - look for any loose components...

t..

 

maybe you have a tire that is out of round.. or excessively worn

 

my rotors shook because we didn't tighten the 32 mm' socket enough for the axels....

 

everything is tight. i triple checked everything.

would a tire that is excessively worn or out of shape only cause shaking during braking and not during cruising?

 

i remember mines shaking while going over a certain speed.....and shook a lil while braking but not much....

 

Yeah, u might want to balance your tires now since out of balanced tires tend to shake alot also; but not only when u brake, usually all the time when they are out of balance. Give it a try if nothing else works.
