Hey guys i got a problem with the brakes they are soft but we have already bled the a few months or so ago...it has a new mc calipers cylinders and pads. It has front disk rear drum. Would the drums on the back not being adjusted right take all the pressure away from the whole system or is it most likely something else? thanks guys------------------

maybe, the further they have to travel, the more fluid it takes, hence the softer pedal.

yep.With the wheel off the ground, car in neutral, wheels blocked, and jackstands in place...use a brake spoon thru the hole in the backing plate to tighten up the shoes. Pull down on the spoon to ratchet the star wheel upwards (from behind). Spin the tire by hand and tighten up the shoes until a good pull only lets the wheel go around 1/2 to 1 turn.

Not to hi-jack here, but is that a good rule of thumb for front drums too Scott??? Thanks for the info, and space.

Yep, works on the front drums as well. You want just a little drag to start with. On the fronts you want to make sure the wheel bearing is adjusted correctly first. With the brakes not dragging, spin the drum while tightening the spindle nut (to seat the bearing). Then back off the nut and lightly seat it, I think Ford says 15 lbs-ft on a torque wrench or what I would call slightly better than finger tight. Then install the retainer and cotter pin, then adjust the brake shoes.

I would check the rubber lines, they may be balloning on you somewhere. If they are old, you might want to change them, just to be safe.------------------

Are you sure mushy is the right word? If you have to press really hard to stop, it may be your disc rotors and drums need refacing.
