Lost One Emergency Brake The passenger side Emergency Brake is not working. I removed the drum and found the drum had worn the head off the center toggle lever pin where the connecting lever connects to the two toggle links.
Everything was brand new, including the brake drums 2100 miles ago. I never heard any noise. The drum does not rub on the backing plate. There is very little distortion on the stud plates inside the drum. My question is: Is it possible the drum just had to wear a little? I'm replacing the pin and don't know what else to do. I can buy axle shims but the drum doesn't hit the backing plate but it sure hit the center toggle pin head. Not a fan of axle shims. |
Re: Lost One Emergency Brake Was the pin put on the correct way?
|
Re: Lost One Emergency Brake Concur with post #2. Pin is inserted with the head outside. Cotter pin inside.
|
Re: Lost One Emergency Brake Yes correct

This is what I saw

Re: Lost One Emergency Brake Look at your studs in the drum and make sure they are flat against the inside of the hub that is where they rub. or you might need to shim the hub out. that is real common.

Re: Lost One Emergency Brake is it just me or does the C moon shape piece look like it bends too far out? im not super familiar with standard A brakes (AA brakes are close but different)

I was thinking the same thing. Is there any welding in the studs area? |

Re: Lost One Emergency Brake Is there a correct way to put on the emergency band or does it not matter what side is "in"? I am thinking they can go on either way as long as you can see the pin heads from the outside. Was the C shaped piece in between the 2 connecting arms?
|
Re: Lost One Emergency Brake No welding on studs. All new drums and parts...ALL New every piece. The arm had been connected in between the toggles as directed in the manuals with the toggles installed correctly creating a slot for the arm.
Can I install an axle shim to hold the drum out slightly...is that the cure? |
Re: Lost One Emergency Brake #10 There is an inner and outer facing to an E Band. The two triangular tabs need to rest flush on the carrier along with the two tabs that have the holes for the pins. If the band is flipped over, the band will not sit flush and will be on an angle on the carrier. You would have a difficult time getting the drum on.
There seems to be a lot of wear on the C link which would indicate either the drum is on too far on the axle (would need to shim) and / or the studs are protruding out from the hub or are welded. |

Here is how everything should look. I can't see everything in your picture, so I can't tell why the link and pin was rubbing.

Re: Lost One Emergency Brake jg61hawk,, what year is your A?
|
Re: Lost One Emergency Brake Compare the picture in #5 to mine in #14.
Why does the #5 appear to have a shoulder on the axle right where it leaves the axle tube? |

Re: Lost One Emergency Brake Quote:
I agree with your earlier comment, the connection of the link to the actuating arm appears bent. The link is out further than it should be and causing it to rub. Good Day! |
Re: Lost One Emergency Brake It's a 29. I'll look at the arm and if the axle has a shoulder or grease...or what. I'll get another picture or two. I'll mark the new pin with some paint and spin the drum and remove it and see if the paint is marked. We'll see.

The cotter pin didnt fall out or the pin itself too long to where it could have worked its way out to get hit by the studs did it? |
