Another issue brake drum balance weight

As I was walking back to where I parked my coach, I noticed what looks to
be a weight from a brake drum. Upon further inspection, it appears that it
might have became detached from my passenger side forward drum. How
detrimental/serious would it be to drive the coach without this weight?

As always thanks for help/opinions, etc.

Faye,

That missing weight will certainly affect wheel balance. You need to take
a test drive to see whether it's noticeable -- you'll probably have to get
down off of your mountain to find a level, smooth road. :-)

If you use balancing beads in your tires, as I do, they'll probably
compensate for the unbalance. If you don't you may want to consider that
as an interim fix until you can replace the drum. I use 4 oz of Walmart's
"Airsoft" beads in each tire -- with no other wheel weights. With already
mostly balanced tires, less might be enough, but more shouldn't hurt
anything.

Ken,
Pretty sure know where exactly wt fell off of. Would jb weld or something
similar work well enough to keep the wt on, especially if brakes get warm
in the mts?

The heat will cause the epoxy to burn off.

Fay,

There is now a high temp JBWeld that MIGHT hold it on.

Fay,

Use a clean steel wire brush in a drill to clean the brake drum and the weight. Then get some of this stuff:

i+temp+epoxy+tube&gs_l=psy-ab.12...9192.10963.0.15156.8.8.0.0.0.0.110.798.4j4.8.0....0...1c.1.64.psy-ab..0.2.217...0i13k1.0.Vq9LkeWG
PFg=4525218708089461078

and glue it back on. The weight of the epoxy won't make much of a difference when one considers the distance from the center it is
located and the rpm of the wheels.

Why are you guys avoiding the obvious? Weld it on and be done with it. Cheap, fast and should last forever.

Ken, if you weld it using a stick burner or a wire feed you'll heat the drum unevenly and there's a good chance you'll warp it. Mine look like they
were spot welded for just that reason.

Ken,

The weight is steel, the drum is cast iron and welding steel to cast iron ain't that easy.

Google "welding steel to cast iron" and read what needs to be done to make it last. The very fact that the weight came off shows
that when the drum was made it wasn't a good weld.

A couple of tacks with a welder will not cause warpage of the brake drum and will hold much better than JB Weld. The drums are thick and tack welding is no going to produce much heat to te drums. It not like you are going to penetrate much into the drum to cause a lot of heat. I did this 20 years ago to my brake drums (2 of them) before I went to disk brakes with no problem.

Drums get very hotin normal use and the epoxy will likely burn off with time.

I just talked to my professional welder guy at the airport (now retired). He said bring it by and he would do it in a couple of minutes. No problem
with it being cast. He said that it is not structural and only had to hold a small weight to the drum. He would do it on the coach if the area is
accessible without removing the wheel. His biggest concern was attaching ground so he did not have any welding current running through the wheel
bearings.

Fay, The airsoft beads are so easy and they balance the drum, tire and wheel at the same time.

Decided drum wt will need to wait until get home. Can live with vibration
if that will be only problem. Maybe take care if at one of friends places
will be spending time with.

Just like the welds cracked with time. :-)

I think examination would show that the welds failed due to corrosion.
