REAR BRAKE DRUMS

GMC C2500

How do I remove the brake drums on my 2500 series sierra. It has about 100,000 kms and a 7.4 litre gas engine. 2000 year. The drums are stuck after I remove the wheels. Is it just conventional ( remove the wheels only, slack off the emergency brake adjusters and hammer the drums till they pop off?

Basically, you need to shock the drum off the axle, probably rusted to it

It really also depends on what axle you have. First you need to find out if the drum is attached outside of the hub or inside. If it is inside of the hub then you need to remove the hub by removing the spring clip and square lock key. Then you need to remove the wheel studs to remove the hub. Make sure that you redue your bearings when you reinstall the hubs. If it is on the outside of the hub then it could be rusted to the hub. Then it needs to be jarred off. Also, sometimes the hubs are worn so that they have a ridge on them and the brakes need to be adjusted by turning the auto adjuster. It is accessed through an access hole on the backside of the brakes, on the bottom of the brake plate. The hole is rectangular in shape and about 1/4 in in width and has a little clip to cover it. Use a flat head screw driver and turn it down ( I Believe) on both sides. That will retract the shoes. Remember that once you redue the brakes it is a good idea to adjust them out until you feel a slight drag. (Remember slight drag). It is also a good idea to check your wheel cylinders. Hope this helps

Hi what I did was make a tool the tool fits over thew edges of the drum and bu a 1/2 inch bolt presses off the drum by pressing against the middle area it pulls everything off so if you don't back off the shoes enough you'll need spring retainers. If you're really interested I'll send pics. BTW I beat the drum, heated the drum, stayed out late and went dancing with the drum, still no action. I had to make a tool or ruin the drum by a cutoff.
