i had brake work done at olympco muffler and brake about 5 months ago. at the time, they saved me a crapload of money, but maybe not??? i purchased the OEM brake kit from my dealership, but they were charging 300+ bucks for installation??!! RIDICULOUS! therefore, i went to a local muffler and brake shop called olympco. they charged me 80 bucks!!! everything seemed okay...no vibrations, nothing. they turned the rotors, and everything. however, everytime i brake now, my car vibrates and/or shakes badly?? would this be a frontend alignment sort of thing??
