well i did cheack the booster today, it is fine. Im going tomorrow morning to get a new master cyclender. if that doesnt fix the problem, then it has to be the calipers. one of the pistons could be defective. but who knows. thanks for all the help on this problem. i did find a nother one today as well though. i just noticed that i have a slight miss in the engine. what should i do to try to fix this? there are new plugs and wires already in it. and i ran a can of restore through it today. where should i look next?
