After replacing the rotors and pads on the front brakes the brakes felt squishy after being bled multiple times. At that time no lights were on. I put a new master cylinder on and that solved the stopping issue, but right after replacing the master cylinder the brake light and the tcs light came on. I put new abs sensors on the rear wheels and that did not correct it. Every now and then the service 4wd light has started coming on. I scanned the truck and no engine codes were present but a U0401 (invalid data from ecm/pcm) and a C1009 (low brake fluid level) codes were there. The brakes fluid level had been consistent I check it every day. I think I’ll do the front sensors but after that I don’t know what to do. I had one guy recommend bleeding the abs module? Any help or advice anyone can give to give me greatly appreciated!
