I have a 2001 V6 that I love more than my gf(I pray she won't read this). But the brake system is messing up. It's got a new master cylinder, new calipers, new rotors, new pads, and new hoses. All this was done before I bought it 2 months ago. But 3 of the 4 calipers are locked up/don't work. And the proportioning valve is leaking(not bad, just a lil). I don't make a lot of money so is there a cheap way to fix this? Sears didn't know if fixing the leak would make the calipers work. All they said was I need to do a fluid exchange/flush and replace the valve. Then see what happens. If the calipers still won't work then I gotta replace them. Maybe this is a sign to upgrade to the Cobra brake system? Hard to find Mustangs in junkyards tho. So if ya got extra parts hit me up. I won't pay an arm and a leg. So pls be reasonable.
