My brakes started squealing a little while back. I took it to the bike shop a couple days ago and they said I needed to replace the rotor and the brake pad. After they replaced it, it did the same thing. I have rode several times and went down large hills and pressed the brakes. It kinda helps temporarily, but the next day it does it again. Any advice? I really don't want to have to replace the rotor and brake pad again.
Bike brakes squealing after replacement.

Try cleaning the rotor with rubbing alcohol.
if the pads are rubbing on the disc when you aren’t braking then your calipers aren’t centered properly. loosen the screws, apply the brake and tighten each screw alternately while holding it. release and spin the wheel. if it still rubs, keep doing it until it doesnt. if it only rubs in a couple of spots during the rotation, fix it by bending the disc with an adjustable wrench.
Is it just the rear brake? If so, I’d guess the issue is at the caliper. A cracked piston will leak brake fluid and contaminate the pads/rotors.
