Transcript:
For some vehicles, you may need to loosen the star wheel, which adjusts the brake shoes inward, using a brake spoon. That will allow you to remove the drum more easily.
If you turn the star wheel and it clicks, you’re probably tightening the shoe, not loosening it, so turn it the other direction to loosen it.
The drum should turn freely with very little sound caused by friction between the shoes and the drum.
Pull out on the drum to remove it from the hub.
You can hit the drum with a rubber mallet if needed, but don’t use a hammer or you could damage the drum.
Inspect the drum after removal.
If the braking surface of the drum has cracks, blue spots or grooves, it needs to be turned or replaced, which is a service most of our stores offer.
Once the drum is removed, check for moisture or dampness at the wheel cylinder.
If one wheel cylinder is bad, the other will begin to leak soon as well, so they should both be replaced. Always replace wheel cylinders in pairs.
Spray down the whole assembly with brake cleaner. It’s easier to clean the parts while they’re still installed.
Now’s the time to take a photo, before tearing anything down. Do this on both sides once the drums are off, so you’ll have a way to keep track of how everything fits together.
