Bleeding the Brakes - Manual Bleeding
Hey Forum -
I just finished installing new Drums, Cylinders, Shoes, and Hardware on my rear brakes....and now it's time to bleed. Ha!
When I was bleeding while removing and installing the cylinders I let the master cylinder go to air - then pedal went to the floor.
I topped of the master cylinder. and bled the rear brakes.
Drove the truck and the pedal is way spongy - so I went to the shop manual and read the instructions for bleeding.
Instructions from the Ford Shop Manual say to :
1. On the Master Cylinder, loosen the master cylinder-to-hydraulic line fitting.
2. Wrap a shop cloth around the tubing below the fitting to absorb escaping brake fluid.
AS far as I can tell there are TWO cylinder-to-hydraulic line fittings. One for rear brakes and one for front brakes. Does instruction number 1 mean to loosen BOTH of those or something else.
Thanks for your help!

I would say that if the master went empty, but you haven't bled the front brakes, you have only finished part of the process. In order to completely bleed the braking system, you should start farthest from Master and work in ascending order with the Driver caliper last.
Unfortunately, there is a small amount of air in the system, you should continue bleeding until the pedal produces a firm feel. I know that by yourself, it's hard as heck to get the brakes bled correctly and can be frustrating at times. I bled my brakes a total of 8 times with a helper before I got a nice firm pedal.
Maybe someone else can offer some help regarding the mishap with the Master going dry.

i would just fill up the master cylinder and then start with the right rear brake then move to the left rear brake then move to the right front brake then to the left front brake !
dont pump the pedal just push it to the floor and hold it then loosen the bleeder screw to get air out then close the bleeder screw , then repeat !after every 2nd time that you bleed a brake then check the fluid ! it can take several times per wheel to get air out so dont be in a hurry ! also make sure that the rear brakes are adjusted up but not over adjusted !
