Suburban 3/4 Ton 4WD V8-305 5.0L (1986)
Hold-down Spring Tool
-
Conventional pliers or needle nose locking pliers will work if a brake spring tool is not available.
-
Grasp the top the the spring with the plier, compress, and rotate.
CAUTION: Excessive pressure can easily distort the top of the spring. Any distortion widens the slot which can cause the pin to pop out
during normal operation. If the slot appears distorted or widened it must be replaced.
Installation
-
While holding the brake shoe against the backing-plate, insert the retaining pin from the rear of the backing-plate through the appropriate hole
in the brake shoe webbing. Verify the shoe is resting squarely on the contact pads of the backing-plate.
NOTE: A strip of duct tape placed across the backside of the pin and backing-plate will help keep the pin from inadvertently falling
falling out and will free up a hand to help steady the shoe during the next step.
-
Place the hold-down spring and washers over the pin.
-
With the thumb of one hand hold the shoe steady while reaching around the backing-plate to hold the retaining pin steady.
-
Use your other hand to simultaneously compress and align the slot of the hold-down spring with the pin.
-
When the slot and pin are aligned, further compress the spring to clear the tip of the pin and then rotate the spring 90 degrees.
-
The slot and tip of the pin should now be opposing each other at a 90 degree angle.
-
Verify the tip of the retaining pin is locked into the indents on the surface of the hold-down spring. This will keep the retaining pin from
twisting and inadvertently popping out.
