Brake screeching

I posted this elsewhere and didn’t get much feedback-

I recently replaced all 4 of the rotors and brake pads on my 2011 Tundra with factory parts. Now when I stop it makes a terrible screeching sound. I know it’s coming from the back.

Any advice would be appreciated because it’s driving me nuts. Thank you!

 

Pull the rear rotors off and see if they are rubbing the dust/heat shield. I had to readjust the shields with a hammer and drift. Or just wait and they will remove enough material by themselves.

 

If it only happens when you stop then I would recommend some anti squeal lube on the pins and backside of each pad.
Also verify that the brake wear indicator wasn’t accidentally pushed onwards causing it to squeal even on a brand new pad.

I bought a Camry a few months back that had the same issue on the LF. The pads and rotors looked new-ish.
I had the rotors turned, took the pads out, cleaned out all the brake dust that was built up inside the caliper, then used a tiny bit of antisieze on the edges of the pads that contacted the caliper. Then I put some anti squeal lube on the back side of the pads, tiny bit of antisieze on the pins, and threw it back together.
Good as new.
