I have a question aboat brakes and adjusing them. I have an E150 1988 302
EFI V8. I have replaced everything in the drum brakes in the 2 backwheel at
my car. Everything went well, and I got everything in the correct position.
Inside the drum there are an selfadjusting screw in the bottom. To get
everything back together I had to screw this completely together. There are
a flywheel on the screw which have an selfadjustment plate which shall turn
the selfadjusting screw. So the question: Do I have to adjust this
selfadjusting screw after assembled everything to get the brakeband to lay
until the drum, or will this adjust itself after some driving?
And with other words:
Is it to much for the selfadjusting mecanism to take care of so I have to do
it manuelly to get the band until the drum or will everything fix itself
after some driving?

Tor....I hope you did one wheel at a time when you did the brake job.
The parts don't interchange from one side to the other. The brake
adjusters have R and L imbossed on the socket and on the self-adjusting
Each side needs to be adjusted using the Star wheel which is accessed
through the the bottom of the backing plate (remove rubber seal). Using
a screwdriver or similar tool, engage the star wheel and push the tool
handle downwards to expand the shoes, until you feel a slight drag on
the shoes. After some driving time on the new shoes, the self-adjusters
are supposed to keep the shoes adjusted but I've not found them all that
reliable. I rely on the parking brake to tell me when it's time to
manually readjust the rear brakes. Too much pedal travel to 'set' the
brakes, means it's time to adjust them again.
Hope this helps.......
When assembling, turn the screw so the drums just barely slip on over the shoes.
Drive back and forth 9 or 10 times, stepping on the brakes firmly each time
you're going backwards. You only need to move 5 or 10 feet. This will adjust
Do you remember putting in a wire with a loop on one end and a hook on the other?
That's the part that activates the self-adjusting plate. When you drive
and step on the brakes, the top of the rear shoe moves away from the mounting
post, and because the wire's loop is attached to that non-moving post, the wire
gets pulled (imagine the shoe staying still, and the post moving). Since the
loops around a small bracket on the rear shoe, then hooks onto the spring-loaded
adjusting plate at the bottom of the shoe, when the wire moves, it lifts up the
plate. If there is enough movement of the shoe and the wire, the adjusting plate
into the next notch on the "star-wheel". When you then release the brake pedal,
shoe moves back to the post, the wire gets looser, the adjuster plate is pushed
down by its spring, it turns the star wheel a small amount, and the "screw"
the bottoms of the shoes apart a tiny bit more. That's all there is to it.
