Tech Tip: Honda CR-V Rear Brake Grinding, Thumping or Groaning Noises
A customer may complain of a grinding, thumping or groaning noise coming from the rear brakes. This occurs during the first several stops after the vehicle has been parked overnight. Under normal braking, corrosion from the disc surface is not quickly removed, allowing for a temporary grinding or thumping noise. A new brake pad is now available, which has improved corrosion-removal characteristics.
Tech Tip: Demystifying Honda ELDs

Tech Tip: Shim Calms Chirping Noises in Honda Models
Some Honda owners may complain of a chirp from the lower timing belt area. The noise is most often noticed at idle, usually after the engine has warmed up. The probable cause is the idler pulley mounting surface is tilted, causing the edge of the timing belt to rub against the side of the pulser flange on the drive pulley (gear).
