right front brake started locking up after about a 25 minute ride to work, left the car at work and went there today and replaced the caliper, bracket, and the brake hose, pads and rotors... Started driving again after I was finished and about 15 minutes down the road I notice "automatic braking" lol, I get out, and now my drivers front rotor is glowing red, but pass side isn't... I went ahead and had oreillys order me the drivers side stuff as well, but now I'm wondering if there is a bad proportioning valve or maybe master cylinder to where something is not allowing the fluid pressure to release... Any ideas??

 

Problem fixed, ended up replacing master cylinder and adjusting/ backing off the the pushrod.
