Ok so my front brakes keep locking up too easily and its dangerous as hell. I have the tcs wilwood bbk on the front with supra rotors and deltav rear rx8 rotor brake upgrade with the gen3 calipers.

I haven't driven the car much in the last year but I don't remember my front brakes locking up so easily when I first did the upgrade a couple of years ago.

What could I check to see what may have gone wrong? I have flushed the brake fluid already but will do it again to make sure there isn't any air.

The car does have abs and I haven't disabled it.

What year model is your car?

1992 revision 2

Does it have the 3/4 inch master cylinder?

What tires do you have?

Also, might be an idea to make sure your brake booster vacuum check valve is around the correct way. 

If you have the early brake booster, the check valve is built in, however if its a late model one it's in-line. 

If the car has been sitting I wonder if one of the pistons is starting to stick.
