 |
|
I was wondering if someone can put an 181 rear brake drum on the scale for me and tell me the weight.
With the thick mounting face on the drum I can only imagine that it weighs a ton more than a wide 5 bug rear drum or even a larger Type III drum. I am just curious how much.
Thanks |

Mine were not original VW, but German Sebro reproductions. They weighed 19 Lbs a pop. Heavy suckers. The reinforcement webbing is slightly different than the VW reinforcement webbing.

Thanks for the info.
Interesting that the Sebro are around 19 lbs, and I see Thingparts.com has a rear 181 drum and shipping is quoted as 18lbs, and the orig drum weight around 16lbs. I wonder how much wear is on the original drum.
I will pull one of mine that are very worn and weight it too and report that info when I have it.
Type III drums have a shipping weight of 14lbs and they are a larger diameter drum and use longer and wider shoes.
Just thinking of the unsprung weight savings possibility on the rear brake drums. |

Type 3 drums may not be much lighter if you consider that they are separate from the hub where the Thing drum/hub is all one piece. That Type 3 weight probably doesn't include the hub.
I run discs in front and Type 3 drums in back. I chose to run them because of the longer and wider shoes. The combo works really well and makes it stop almost like a modern car. I am very happy with them. |

Type III early model rear drums are wide 5 and all one piece.

Sorry, I wasn't thinking about the early ones. I used the later model along with 4 lug discs to convert mine to 4 lug while I did the brakes. |
