lastpushbutton, if your front locked up, DO NOT remove the proportioning valve. If you do, more brake power will go to the front, less to the rear, making your brake balance problem even worse!
I'm puzzled people think that the factory put in the proportioning valve to make the car brake less efficiently, it has a purpose.
Here's what you should do.
-Either keep brakes pretty stock and keep proportioning valve
or
-Buy entire brake set from a knowledgeable vendor, they will see to that you get good brake balance from their system. Some systems will have proportioning valves, some not, not important as long as the whole system is balanced
All that said, if only one front wheel locked up, look at the other front wheel, is a caliper piston stuck? Brake pads gotten hard like glass? Fluid leak? Maybe a new set of pads all around?
Hope this helps, and drive carefully
