rear drum brakes

On these brake drums you do not need to measure any clearance on them because they have automatic adjusters.

Here is a guide that will help with this:

However, when you first set the drum, you need to use the star adjustment screw to set the initial point. You do this by adjusting it all the way in, install the drum. Then extend the screw through the back of the backing plate until the shoes just slightly drag the drum.

At this point you just step on the brakes and the adjusters will tighten them if needed.

Please see the process attached below. Let me know if you have questions on this.
