Removing brake drum rivets..
before I pull out the grinder, I want to confirm these are the three brake drum rivets I need to grind off..
![]() ![]() If anyone can answer quickly - I have the thing up on jackstands and really want to get this done today. I am kind of shocked to see intact rivets.. the truck is 40 years old. Also, I have already adjusted the brakes all the way up and down, so I know the shoes are not holding it on Last edited by chrislehr; 01-30-2010 at 02:49 PM. |

Re: Removing brake drum rivets..
Yes that would be them.

Re: Removing brake drum rivets..
their the ones, you may have to grind them off and knock the hub out of the drum and then grind some more to knock them out the hub

Re: Removing brake drum rivets..
Eliminating those rivets will allow you to separate the drum from the hub. They are a little harder to handle/reinstall, when separated, but you have to start somewhere!

Re: Removing brake drum rivets..
You don't have to rivet them back on. I drill them out with a 1/4" bit almost all the way through and chisel the head off and punch out the rivet.

Re: Removing brake drum rivets..
the stock trums were made properly when men were men and steel was steel. They have been known to last well over 100k.
If your originals are still good, then put them back on. The replacement ones are junk IMO. |

Re: Removing brake drum rivets..
I guess I should have made post #1 clearer - I was trying to check the pads. Luckily, didnt get the rivets all out before I was told to remove the axle bolt/dust cover. Doh.

Re: Removing brake drum rivets..
while I have a thread going - whats the purpose of the spring coil wrapped around the drums?

Re: Removing brake drum rivets..
my guess is the springs were used to keep tention on the drum from warping when getting hot or overheated. But not shure!! some one can chime in and educate me
![]() also when hammering the rivets out, Be careful!! i kind of got crazy with the hammer and bent the wheel hub in three places where the rivet sat and i was really shock i actualy bent the hub!! I would prefer to drill the rivet out completely

Re: Removing brake drum rivets..
The spring was used to quiet the harmonics. That's the only use I know for them.

Re: Removing brake drum rivets..
I agree with the harmonics... a slight ringing can be heard if the spring is missing, some will tell you it is for cooling though.

Re: Removing brake drum rivets..
yup the spring around the circumference is there to dampen harmonics that could cause unwanted noises during brake application.

Re: Removing brake drum rivets..
Some guys have to knock the rivets off so alloy wheels will seat flat on the drum but the only other reason to cut them off would be to replace the drums. By the way, drum brakes don't have "pads" they have "shoes".

Re: Removing brake drum rivets..
My 68 still had the darn rivets in place and I'm sure my truck has a billion miles on it. Shocking that they last so long.

Re: Removing brake drum rivets..
As you can see the bend in the hub from hammering on the rivet after the head was grounded off, it was bent all the way around where the rivet sat!
I didn't realize it was bent after 5,000 to 10,000 miles driving on the new shoes and drums. I didn't get any vibrations at all luckly!! both drums still in good shape and no lip but different type! one has rivet holes and the other without, both were bought at the same time here at Chicano Zone!! ![]()

Re: Removing brake drum rivets..
they also don't have the holes for adjusting the shoes up, or the lip for the spring.

Re: Removing brake drum rivets..
This is the reason for drilling the rivets almost all the way through. When you drive them out the colapse inward and come out very easy.
