Drum brakes

[loverofchevystrucks]

HEY EVERYONE. I HAVE A 1978 CHEVY K20, AND I AM TRYING TO GET THE DRIVERS REAR DRUM OFF BUT HAVING NO LUCK. EVERYONE IS TELLING ME THT THERE IS A HOLE TO BACK THE BRAKES OFF IN THE BACK BUT I SEE NO HOLE. THERE IS ONE IN THE DRUM. WHEN I AM GOING LIKE 10MPH OR SO AND COME TO A STOP THE DRIVERS SIDE REAR LOCKS UP ONLY GOING SLOW AND IT STICKS WHEN I AM TAKING OFF. ANYBODY HAVE ANY IDEAS. THANKS FOR READING

Yeah the brake shoes are out too far. Or, the passenger side is not working/seized up; sending all the fluid pressure to the driver's side.

There should be a little hole either on the backing plate, or the drum, that you can take a small screwdriver and turn back the little wheel that adjusts the brake shoes. Sometimes the backing plate hole is covered by an oval rubber plug.

Now being a '78, it could be frozen. So some times I have resorted to prying the drums off, and tapping on them with a hammer (carefully to not crack them) to vibrate and "bounce" the shoes off of the drum a little at a time.

Line the drum hole up at the bottom of the backing plate. You should be able to see the adjuster. it will be toward the rear, it turns up to loosen. You may have to cut the hold down nail heads in the backing plate if the adjuster is stuck. Jay

mine does the same thing i took it all apart and i had a helluva time getteing the drum off it was because my axel seal is leaking causing everything to stick when mixed with brake dust

there could be a slot in the front of the drum but most of the ones ive seen ( im not a 4wd guy) are in the backing plate and youre able to stick a screwdriver in there and pop the arm on the self adjusting mechanism so you can back off the adjustment on the star adjuster and then release the drum.
If you have a heavily gouged drum this may be a real PITA cause sometimes the shoe groves into the drum and you have to beat the snot outta it to get it loose

you should pull both sides and check the wheels out you may have too little on the pass side or there could be a kink or something with the line to the drivers side

Take a look at the backing plate and look for a semi-punched slot. The guy doing the first brake job would finish punching out the slot and after performing brake service would seal the slot with a rubber plug.

If the drum continues to resist your best efforts....try a brake drum puller.

Merged....Please don't do this. Multiple posting is againstthe rules for a reason. It makes for major confusion.
