Have a 2002 first generation Tundra 4.7 2 wheel drive with no abs. I've been having the issue of the brake sticking especially on first starts or mostly on cold weather. Toyota dealer put a brand new frame (5/26/2020)with new brake lines before that I had replaced all the rubber lines and calipers along with all the hardware to the brake shoes in the rear. I inspected the rear brake shoes and drums everything seems fine was about to replace the booster or the master cylinder but none of those have any visible issues. After the brakes are released they become very sensitive to the touch of the brake pedal. I'm a little lost of what to do next need a little help.
