So, I was driving back to my house when I started to feel alot of strain on the motor and I was slowing down for no reason. I give it more gas and realize there is a problem and pull over to find smoke coming from both front calipers. They are locked up and locked up good. I have noticed recently that the car is hard to push but figured I was getting soft and never gave it too much thought. I have 99 front Cobra calipers with 95 spindles and 13" stock rotors. I have dicount auto pads and 95 front brake hoses (rubber). I also have 95 brake booster and 95 master cylinder with a 3 to 2 port conversion. I know these parts are not ideal with stock drum brakes but it has not been an issue before yesterday. Long story short where should I start to look for the problem???? First thought was the stock porpotional vavle?? Thanks
