Anti Rattler Pics

I am installing new anti rattle springs on the rear service and e-brake rods. I think I have them installed like Les Andrews' illustration, but they don't look right on the car. Does anyone have a pic that shows how they're installed?
Thanks!
 
Hope this helps

CHANGE IN BRAKE ROD RETRACTING SPRING

A change has been made in the brake rod retracting spring.
The depth of the spherical socket in the spring has been increased to give additional bearing surface around the button on the brake rods (see Fig. 821). This change lessens any possibility of the brake rods slipping out of the spring sockets and causing a rattle.

The front mount on the front side of the bracket, and the rear mount on the rear side of the bracket.

Now, which way does the mounting bolt face?
 
For service work and generally I like the '31 wire type. They work much better.
See service bulletins Sept/Oct '31.

You don't have the rattle problems with these like you do the old ones.

Well I guess no one's got any pictures! Ok let's take another approach. Here's mine. Brake rods and springs from right rear. What's wrong with these pictures?

i had to bend my repo springs to look like the picture in the service bulletins.
if you put them on out of the package they tend to sit like 29 Cabriolets pics

Tom,
Here's the photo from the service bulletins.. I believe Sep/Oct '31 from my garage copy reprint. I think these work great.. and certainly don't break like the old flat spring type and don't rattle either. I can also put these on without removing brake rods, by cutting the old ones off, and then opening up the new ones at the split and putting them on, and closing them back up. Makes switching over fairly easy. Whenever I do brake work on one that's in my shop these are what I use unless it's a point type car.

Larry, I knew what you meant, and someone's old wood screen door is missing it's spring. I still haven't changed those, as they were on my 28 Phaeton when I bought it.

Mitch, I also have to bend the repro flat springs to get a proper fit and to give better return pressure.
 
That could be the problem. The way these are mounted, the service brake spring is behind the button on the rod. The e-brake spring is in front of the button on the rod.
 
Also to it could very well be the bracket that is welded to the Rear Radius Rod Assembly (RRRA)...I was in the same prediciment and thought that the springs themselves needed to be bent...Even put a post on the barn on just how to bend them to get the correct shape...No takers!

THAT WAS NOT the problem. I started to compair the bracket angle to the RRRA on others that I have and found out that the brackets were bent so I took a happy medium on all the brackets on other RRRA's and BINGO...bent them to the right position and then there was no need to bend the springs!

Pluck

That is a fairly common issue, as is improperly shaped springs. However it's difficult to tell for sure until the brake rods are installed. The bracket should then be tweaked if needed to make it 90 degrees to the brake rod.
 
I agree that 29Cabriolet's service brake rod spring appears to be on backwards. Here's a photo of mine (RH side, taken from the rear). Pardon my pati..., er surface rust!

Also note that both springs attach to the front side of the bracket.

If the nut for the mounting bolt always goes against the springs (Mitch//pa), then mine is wrong way around?? Is there a practical reason for this (you can guess that I'm not into judging ;)).

OK. What is correct? The service bulletins Larry posted show the springs on either side of the mounting bracket...one on the nut side and the other on the bolt head side, NOT both on one side. Marco's pic (if that's his pic) shows them both on the rear side of the bracket. I attached my late 31 wire springs together on one side and never did like the way they sandwiched together. I'll fix that tomorrow according to the bulletins and see if I like that better. Just wondering.....does it matter?
 
Rusty,

I've done them both ways.... I think the important point ( for service over judged car) is that they have a good "spring" working anti rattle alignment. The bracket is correctly positioned ( bend if necessary for correct right angle). I looked at my Tudor where they have been on there for many miles and I have them both together at the rear, bolt in from front, nut & lock washer to rear. They worked well. I have/think I generally do them as shown in the service bulletins with one on each side as it's honestly easier to mount and tighten and funcionally better.
I don't think it's one to overthink... but I definately feel the later '31 style do a better job. Like Tom said with the flat type.. I have had to bend them to get a better funcional fit/alignment in the past when I have used them. The spring nature of the wire type are much better and positive natured.

PS Always liked your avatar photo. Coupe body looks great. I will have to add a photo sometime... probably something KRW or something.

Happy New Year to the Barn!

I consider this drawing correct,....the return springs are pulling on the tab.
