Well on my nogaro back in march i had a master go bad and the brakes locked well on my way to work today and i noticed my foot was in it to keep it moving. This time it was only rear. There was a nice amount of smoke pouring out the rear, the front was cool. last time it was right front and left rear. that makes sense why it was the master this time im going to say its not the master because its just the rear, sorta like the ebrake was pulled.{i checked it was not.} pulled the rear brakes apart and nothing i can see is wrong. ebrake returns with no issue. well checked it later in the day and no issue. Im sure it will leave me stranded. any ideas guys?
