hard brake pedal
I'm having an issue with my brakes. Most of the time when I hit my brakes its like trying to mash a concrete block and has very little stopping ability. When the pedal actually feels normal, it stops better but not great by any means. I thought maybe it was my vacuum pump but I pulled the main vacuum line and it seems to have good suction. I have new calipers and pads on the front and I bled the lines until there were no bubbles. I have no idea about the rear drum brakes as to how old they are. I'm thinking a master cylinder or booster problem or maybe both? Any other suggestions?

When it's hard most/all of the time like that, it's generally either vacuum or booster. I've also learned that anytime I replace a booster now, I replace the master cylinder at the same time, as often there are issues there as well. (Often a seal in the master is starting to leak, the fluid kills the booster diaphragm.)

Brake Light possibly caused by dieing vacumm pump - Oilburners.net
Read my thread ^^^^^
My vac pump would easily pull 25 inhg at idle even right before it died.

While we are on the subject, my brakes are stiff if I hit the pedal fast but if I slowly depress it, the brakes are soft and the pedal travels further. Is this vacuum related?
Someone cut me off the other day and I was surprised when I stomped the brakes and nothing really happened. They didn't seem to move from the hard position, ie: they didn't suck down or at least not quickly.

there's no comparison in the braking power.
if you want to stop without the mushy brakes,that's the cure all.
iv got a hard pedal cus i haven't swapped to the f-super duty pedal yet.i dunno where to buy one.
LSO,if you find out you need a vacuum booster send me a pm if you don't mind a used one (under 80k miles.)
