im posting because i need help with my truck.

recently me and my girlfriend got a brake job done on the front and rear brakes. in the front new rotors and pads.
the truck brakes really good but squeals when coming to a stop after warming up. we brought the truck back to the mechanic 4 times and it is still squealing ... dont want to keep bothering the mechanic because he is looking at it for free

if someone can help thanks!

Like a belt squeal or tires locking up squeal?

could be a cracked brake pad.
i had this exact issue on my front driver side after new pads and rotors. turns out a brand new brake pad had a crack in it so the surface was uneven causing a horrible screeching sound

It could be also a glazed brake pad. Meaning, a brake pad that has been over heated and has melted the pad material on the surface casuing a non braking surface. Please drive careful and have the mechanic change pads for you.
