i'm working on my wife's 85 monte carlo that has a bone stock 305 in it. every thing is stock.
about two years ago i change front rotors & pads & it just didn't seem right. well i lived with it, but about a month or so ago i change front pads & rear shoes. the back brakes started locking up a little in my gravel driveway going down hill. i had never put rear shoes on it so i put them on too thinking that might fix that. well it still does it. after i go down the road about a 1/4 mile the rear brakes stop locking up. i checked them & loosened them up, made sure they were clean & they were clean other than brake dust. no grease or brake fluid on them at all.
the brake pedal just sucks. it has for two years now. the pedal will go down about half way & then it starts getting real hard to mash. i can mash it hard & the car doesn't slow down that much. i can slam them & they wont grab hard like they should. they will not lock up at all. i changed the brake booster tonight & that was a waist of time, just as bad as it was.
can the master cylinder do this? what about the proportioning valve?
