Thank You, Thank You, Thank You!
Trying to put it back together after a few weeks. YUP took both side off, Had to. Recovered my Dad's 63 that had been sitting in the same spot since 91 a few weeks ago. He had to replace the rear end back in the day. Had to pull the rear drums and brakes just to get it to roll up on the trailer. PB-Blaster, Heat and sledge hammer plus 4 hours equaled 1 read drum off. The right rear only took 2.5 hours. The fronts rolled somewhat. Some parts just crumbled, and a few I must have dropped and lost.

![]() Mr E, can you take a picture of the brackets you have there. I recently did this same install this past weekend (1st time I might add) but failed to get a shot from the bottom side of the brake system. If you can post a picture of the brackets I think we could walk you through it in a snap. As far as adding the e-brake after the drums are together, I think you are our of luck, unless you have extra small hands.

Re: ???Drum Brake Assembly???
Can the ebrake cable be installed "later on"? I'm considering ordering one of those stainless ones from Inline.

Re: ???Drum Brake Assembly???
umm i dont think so, well i guess you would have to take your brakes back off when your ready to install yr new ones, but that will be a snap after you do this once it wont take long, are you gonna go ahead and replace your wheel cylinders while your at it, there only like 10 bucks each.

The shoes are on backwards. The short lined shoe is the primary and goes to the front.

Question: There's two different style springs for the nail heads, which one goes where? One is tapered in slightly, and is such a small difference that I wonder if it event matters? |

Special brake drum thank you
![]() I am about to build the rear brakes on a 67 gmc c2500 3/4 ton. The rear brakes, nor emergency brake cables etc... do not exist on the truck so this thread has been very helpful. Thank you so much for posting the link to the "Brake Drum Assembly How to" it is for a 6 bolt hub but the setup is the same as the 8 bolt floating hub from what I can tell. |

Re: ???Drum Brake Assembly???
Can anyone get a photo of a 3/4 ton axle please. I can't seem to figure out why I mixed up the two brake struts and now I cant remember where they go besides at the top in between the brake shoes and under the wheel cylinders.

Re: ???Drum Brake Assembly???
the truck is facing right in the photo. This is a picture of the right side of the truck. See the emergency brake cable?
I screwed it up first because I was working on the drivers side and didn't think about the fact this pic could have been of the passenger side. |

Re: ???Drum Brake Assembly???
Does anyone know if all truck 12-bolts use the same shoes and such?
For example; does 63-72 all interchange or does the 73+ 12-bolt also interchange with the earlier 12-bolts?

Re: ???Drum Brake Assembly???
Lostmy65, also researching 12 bolt drum brake options, thinking of changing my 65 rear brakes to the newer 12 bolt heavy duty "JB 5" brake package. Just starting to see if it will work. Looks like the backing plates are different from earlier ones, offset to the center of truck to account for the wider brakes shoes. As notes here before by Keith Seymore, this is one of GM's really good brake systems, used as a design goal for trucks.
Any information/can it be done, on retrofitting rear JB 5 brakes to the early 12 bolt 2" brake shoe axles? Note: using '79 Dana 44 front axle, with the JB 5 brakes. I am planning to use the complete JB 5 brake system on '64 K10 build. Keeping all the original '64 parts so they could be retorfit later. Les |
