I¿ve had the breaks grinding noise coming from the front breaks when driving and use braking. It seems that the brake assembly was coming loose and need to get it fixed with a workshop nearby.
Grinding noise on rear driver's side brakes--discovered missing bolt on caliper frame, brake pads badly worn. All other brake pads in great shape, showing little wear. Car is driven in rural area, with very little city driving. When I went to Hyundai to buy a new bolt the parts guy said "this happens all the time" I think there must be something wrong here. Also checked on line finding I'm not the only one having brake problems on the rear wheels.
The contact owns a 2008 Hyundai Sonata. The contact stated that while engaging the brakes it produced a grinding noise. A local mechanic inspected the vehicle and determined that the rear brake system was defective. The dealer was contacted and advised the contact to have the failure diagnosed. The manufacturer was contacted and did not offer any assistance since there was no recall for the failure. The failure mileage was 29,000 and the current mileage was 30,000.
Car had 19,000 miles on it, I bought it new. Grinding noise from rear drivers side wheel took it to dealer and was told that the rear caliper was not releasing which ruined the brake pads and rotor. Told the car was not safe to drive. The rotor, caliper and pads had to be replaced. Dealer covered the cost. Never had brake problems with any other of the other cars I owned. My miles are highway miles and I do not have to use the brakes as often as I would in the city.
The contact owns a 2009 Hyundai Sonata. While driving 35 mph there was a squeaking and a grinding noise coming from the brakes. The pin that controls the brake pads and rotors was worn. The pin controlled the movement in the brake calipers and when it does not move it deteriorates the calipers and rotors. The vehicle was taken to the dealer who stated that she had to replace the brakes at her expense since they were not covered under the warranty or recall. The manufacturer was not contacted. The VIN was unavailable. The failure and current mileage was 27,000.
