I put on my ebc pads, rotors, and some goodridge brake lines. When I test drove the car today, when I hit the brakes a little more than loosely It shims a bit like it was pulsing under my foot. Could it be because the pads haven't had a chance to bed yet, or is it because I drilled out the rotor screws. I've drilled them out before with no problem shimming and I figure the wheel holds the rotor on. Any ideas? thanks for your help

 

ttt I sure would appreciate any insight.

 

maybe you over torqued the lug nuts.

LMFAO.....

did you resurface your rotors ??

 

i just had the same problem. i installed brembo rotors and carbotech bobcat pads and it was shimming at first. But once i bedded the pads it went away. Try serval runs from 40-60 down to 30 with hard pressure. good luck

 

A shimmy is common after taking the rotor screws out because its not held flush against the hub. If they have been off for a while, take the rotor off and clean the surface of the hub that contacts the rotor. Sometimes gunk/rust of whatever gets in behind there.

 

I didn't resurface the rotors they were brand new. Thanks for the help I guess I'll just wait for the pads to bed. I'll also take them apart and try to put new screws in to hold the rotors. It is very possible I over torqued the lugs, but why would that cause a problem? Thanks for your help.

 

DO NOT put rotor screws in. Unless you like to dick around with them when you need to remove your rotor. If you do, use copious amounts of anti seize on them. They serve no structural purpose, but you knew that already.

Get a dial indicator and check the runout on the rotors, make sure the pads are seated in the caliper properly and make sure the mating surfaces are clean. You might want to lube the caliper pin sliders, too...

thanks for the advice. I didn't really want to put the screws in anyway. I'll lube it up and make sure everything is installed correctly. Thanks for your help. I put 50 miles on it in the last week and its starting to feel a little better. thanks
