2001 Ford Ranger 6 cyl Two Wheel Drive Automatic 145 miles
I replaced the front calipers and the master clylinder on my Ranger. The brakes had failed. I bled the rear brakes and went rr-rl-fr-fl and bled each brake 4 times. I still get a loose pedal to the floor when the engine is running. I bled the master clylinder. How I did a booster brake test by turning off the truck, pumping the brakes half a dozen times and then turning on the truck engine. The pedal doesnt " drop" a little then slowly rise a lil. It just goes down to the floor when pressed. The Brakes do engage but very little.
Everything I read says that the pedal should feel hard when braked if the vacuum booster is bad.
How do I check the brake booster and its vacuum line? Are there any special tools needed or procedures to change a brake booster - out to re-vacuumize the line to the master?
