The front brakes on my 2008 acura rdx make a loud grinding noise when applied on a slight downgrade or when stopping slightly harder than normal. i experienced w/ original brakes, repeated visits to dealer heard & found nothing. at time of brake replacement, brakes were fine, noise started again about 15k miles into the new brakes. took to dealer on sat they again find nothing report pads/rotors normal. the dealership now states that acura is aware and has no fix for the problem. the brakes feel like they are grabbing onto the rotor. feel mushy, rubbing and slow to stop. the sound is similar to metal to metal grinding. had a loaner and brakes were 1000% more stable. *tr
