Every time i slam on the brake , it squeaks like brake pads are done. But dealer checked and still got 50-60% so what's happening?

Had the same problem. It was suggested to me to use this. I did and it's awesome. It's the dust created by your brake pads. Clean your wheels with this and at the same time spray this over your calipers and brake pads. Rinse and no more squeak. Eventually the squeak will come back but it takes a while. This is the best option.

Oh follow directions on bottle. Wet wheels first then spray. Wait 15-20 sec then spray off. Make sure you get the cleaner that is safe for all wheels.

Heres a link to a thread with what you need.

Try this.
Find a quiet road, & do 10 quick hard stops from 60MPH to about 5MPH....in quick succession.....Do not stop.
That will get your brakes quite hot, & should get rid of any built up rubbish....which could be causing your squeak.
I would suggest it's worth a try.
