alright...it feels like the brakes are seized up and the brake pedal gets real tight at touchy when ive been driving for a solid 25 minutes...im used to working with air brakes so i have no idea what it could be lol.

is there like a proportioning valve or something? its only the front brakes that feel like theyre locking up...

yeah i think there is a proportioning valve on the m.c. but i dont think it can be adjusted or anything

now you say they feel like they are seizing up, or they like...are locking?

and tight as in its not being boosted anymore? or what?

honestly this has me baffled maybe somebody else can chime in on this one

edit: maybe one of your pistons is bad or something?

I'm having this exact same problem. I replaced the rear pads and now when I first drive the car, I have to push the pedal halfway to the floor before the brakes engage. Then a while later I barely have to touch the pedal before they are on. I don't understand it!?
I had to adjust the rod going to the master cylinder so that the brakes wouldn't drag after several minutes of driving.

a seized piston in the caliper would cause this. Pushing the pedal creates pressure and moves the fluid pushing out the brake pistons. If the pistons are stuck in the out position, the fluid doesnt come back and there will be little to no pressure until a certain point in the pedal... I hope this is clear cuz i dont wanna draw out a diagram
