Brake pedal travel

[Jspafford]

I have a 1989 Bronco II that I am not sure if I have brake problems with or not.

I took the calipers off and had the rotors turned because I was getting a pulse in the pedal. The brakes have always been fine.

I had the rotors turned and put it back together. The brakes worked, but I could push the pedal all the way to the floor now.

I bled the brakes and it didn't help at all.

Ford said I needed a master cylinder, however I pulled both lines off and put a plug in the master cylinder ports and started the truck and hit the brakes. The pedal would barely move... Meaning the master and booster are fine.

When I hooked up the line going to the rear brakes only the pedal was VERY firm and the rears were working good. As soon as I hooked up the line going to the front the pedal went to crap again. I looked over the front lines and they seemed fine.

I bought two calipers and put them on. Now the truck stops much better, but the pedal still have quite a bit of travel in it.

What gives?

Probably are the brake hoses. Once the outer rubber cracks the hoses will balloon under a hard pedal and the pedal then feels soft.

Pretty easy to check, jack up the front on both sides so the wheels droop. Check for cracks. Then start the vehicle (in Park or N with rear wheels blocked and parking brake on). Press the pedal hard, lock into place with a CLUB between the seat and pedal, then go look at the rubber brake lines.
