I recently had new rotors, pads, and front cv axles replaced on my S8. The mechanic never greased the calipers so I took it back because of squeeling brake noise and right front caliper not retracting. He could find nothing wrong except not greasing which he did and noticed upon yesterday after braking a little hard some smoke coming from calipers which I interpreted just heat and overgreasing? Rotor on from right is still feeling like it is sticking.. And brakes still squeel. What would be recommendation for this problem? New calipers, rebuild calipers? Also feel vibration when turning the wheel on sharp right turn. Bushings? Thanks for anyones help with this.. Drivin me nuts..
