2018 Tacoma brake shidder

Hi all, new to the forum and first time Toyota owner. I think I should have done some research before buying. I se a lot of pasta for a brake shudder when braking at 30 mph and slower. I am at 1300 miles. Had the drums cut then replaced. Replaced front rotors and still there. Now there is a vibration between 49 and 53 mph while cruising. If they can’t fix this I am going to lemon it. Any thoughts??

 

I'm having the same issue, don't know what to do, only had the truck a month now. I took it back, they resurfaced the rotors, didn't fix the problem. I did read something about the motor shutting down to save fuel and assist with braking, but what do I know? If you lemon it, please let me know what steps you took.
