Rear drum brakes
I have a 1993 GMC Sierra it was modified by the
previous owner and is now a 3/4 ton 2500. My rear
brakes have locked up on me twice and I am sure
this brake job is long over due. I have my rear
driver side tire off and the truck is in neutral. I have
used an entire can of PB penetrating lubricant. I
have hammered around the drum and also tried
heat. I assume there is something simple and
important I am missing. So how do I get this drum
There is a plastic cap on back of drum near bleeder location,pop cap out use a brake tool to adjust and loosen the brake shoes inside the hub so you can get it loose.
Is there anything else it could be? I'm not seeing anything like that. I bought a tool earlier today and the guy told me something similar. He said just remove the dust cap and adjust the pads. The only opening I see here is a pen sized hole and a slit on each side.
Thank you for the diagram I'm looking at it different now.
It is a slit about 1" long 1/4 or so wide,use the tool to rotate the star.
That helps, and you may have to punch out that tab to gain access. When hammering on the drum pound in-between the lug studs on the face of the drum while applying some pressure on the edge of the drum like using a screwdriver between the drum and backing plate. Just don't bend the backing plate, you do not need to pry that hard. It will pop loose. This is a recommended procedure from a Manufacture and it dose work.
