Let me ask it a different way..
Front brake rod return springs. The later wire type.
I have the rears in place. They function well. I need some help understanding how the fronts assemble. Here's the scenario..You are standing on the left side of the car. Body is off. The front of the car is to your left. The rear is to your right. You are looking at the left front brake rod. You see the raised "upset" in the rod where the spring rests against. Does the bottom loop in the wire go to the right of the upset or to the left of the upset? Larry

Re: Let me ask it a different way..
All the anti rattler springs are mounted so that they help retract the brake rod to the off position, which is to the center of the car. The fronts are installed on the front side of the upset, to retract the rod back to normal. (brakes not applied).

Re: Let me ask it a different way..
The springs job is to release the brakes.
The rods are pulled to apply the brakes and pushed by the springs to release. So the front rods are pulled to the rear to apply and the rear rods are pulled forward to apply. The springs return the rods to the released position. Another point. The spring should be installed on the frame bracket side closest to the wheel in order to try and exert the most force toward the wheel upon release. [ To help exert more force, I've added black painted washers to try and help old worn springs to be better at their job.] Last edited by Patrick L.; 02-10-2016 at 05:35 PM. |

the rods towards the center of the car. Off would be towards the front of the car for the front brakes. Bob |

Since the rods are pulled, then the springs need to be installed so they now push the rod to the released position. The released position is toward the front on the front, so, by my thinking, and memory, the spring would push against the the 'rear' [ right] side of the upset if facing the car on the left side. |

Measure center to center distance of the rod, remove clevis, install spring and reassemble if you can't get the end thru the spring eye. |

Re: Let me ask it a different way..
With the view you described in your first post, the spring is to the right of the upset. A better way to describe it is that the spring is pushing the upset forward to the front of the car for the front rods. In other words the spring is pushing the rod towards the brake. On the front brakes, the adjusting clevis is at the brake side.

Re: Let me ask it a different way..
On the spring type anti-rattlers I have the loop for the upset is oblong,the brake rod eye goes right through it.All clevis's go on the forward ends of the brake rods.All six of them.The anti-rattlers push the front brake rods to the front of the car,and the rear brake rods to the rear of the car.Remember,the brake rods pull,not push.

Re: Let me ask it a different way..
With repro brake rods I find the rear of the front rods are a bit wider than original ends, and I have to grind them thinner to fit through the slot in the flat springs.
Aren't the wire springs just bent to form an oval loop, so they can easily be spread a little if need be? |

Tom.. Got the wire springs from Snyders. Will see tomorrow if I have to pry them open a little. Actually, they should fit through the oblong hole like Keith said. This was a tough nut to crack.. Thanks to all! Larry

Re: Let me ask it a different way..
I wish I had access to them right now, won't for a few months. Mine had the clevis's at the brakes, but, seems like I saw or read they should be at the cross shaft so thats where I put them as I think I may have had a similar issue as Larry. I don't think it makes a difference where they are except for judging standards. |

Re: Let me ask it a different way..
Unless the UPSET is in the exact middle of the brake rods, it will make a difference.
The clevises all face the front of the car. |
