Brake Problems
Hi guys,
I have a 1978 f-150 Custom.The truck sat for about 15 years, and was driven little to none at all during that time. I've got it back on the road, but the my brakes don't seem to have much stopping power at all. The brakes are working, but they don't lock up, even if I slam the pedal down as hard and far as it will go. Cant skid the tires. So far Ive replaced the booster, master cylinder, front calipers, rear drum cylinders, front brake pads, bled the lines and bench bled the master cylinder. I've also adjusted the push rod in the booster. Im running out of ideas. Haven't replaced the brake pressure differential valve, but my understanding is that this helps distribute even hydraulic pressure to the front and back brakes. Any feedback is much appreciated!

Adjust your rear shoes through the "adjustment slot" on the backing plate, move the shoes outward until you can hear them scrape on the drums while spinning the tires. You would be surprised how much pedal travel this excess slop can take up. it's like a new brake system after properly adjusted.
