I hear a clunking sound on the first brake application. If I put car in reverse, I hear a clunk on first brake application. If I put car in drive, I hear a clunk on first break application. Only the first time I apply the brake do I hear a clunk/pop, no sound thereafter... until I drive in the opposite direction and apply the brake for the first time. Took to dealer. Told him I've been hearing the sound since new, but has gotten much worse at 40K and service manager says he's heard of this complaint before and it is simply the pads moving in the caliber. I paid to have tech look at it and sure enough the recommendation was "no problem", this sound is normal on 2008 corrolla and is just the the pads moving in the caliber. This sound is evident to passengers and pedestrians who are alarmed... sounds unsafe... any ideas?
clunking sound on first brake application on 2008 Toyota Corolla

It also sounds to me like the pads are moving in the calipers on your 2008 Toyota Corolla. While this noise can be annoying it is usually not a safety issue. I did find a technical service bulletin from Toyota related to brake bad noise which they are describing as "rattling over bumps". If the pads can rattle over bumps they can surely clunk on apply. Perhaps performing the repair outlined in the service bulletin will help with your noise - here is the bulletin number T-SB-0046-08. Please ask your dealer to see if this bulletin applies to your specific model.
