Rear Backing Plate Bolts
Pulled my rear drum on the tudor to check brake lining wear and axle bearings, and found a problem with the bolts/nuts that hold the backing plates on. It looks like there is a spacer or something missing, although I have checked the exploded drawings and everything looks to be in place.
I measured the bolts and they are correct as far as I can see - 1 17/32", 1 7/8". Both the short bolt and the long bolt are off by the same amount, not allowing the use of the cotter pin. Any thoughts? |

Re: Rear Backing Plate Bolts
Here are a couple pictures of the rear baffle on my 29 ccpu.
You can see they are different from yours, and they have the spacers between the backing plate and baffle The spacers are attached to the baffle.

Re: Rear Backing Plate Bolts
Dan,
I don't remember any spacers between the backing plates and the emergency brake carrier. I took some pictures of the baffle style I plan to use on the 29 phaeton and 29 CCPU. There is no spacers on any of the baffles and I have 4 of them. I don't know why the bolts appear to be too long. Maybe Dudley would know. It is a job to remove the rear hub to check the bolts/nuts on my coupe. I don't remember the cotter holes being past the slots in the castellated nuts when I assembled the rear end on the coupe. I vaguely remembered that when I was getting the rearend mounting fasteners cad plated there were 2 sizes of the nuts. I dug through my rearend goodies and found the 2 different lengths. I have no idea why there are 2 lengths. Maybe that is part of the problem you are having. If I were you, I would slip some lock washers under the nuts, as I think you have everything correct.

Re: Rear Backing Plate Bolts
Searched "rear brake baffle" and it seems that the early baffles had 3/8" washers/spacers spot welded on the back side of flat back baffles. Later baffles had stamped 3/8" spacers. My early 28 Tudor had the spot welded spacers. I installed modern shocks and had to replace the baffles to accommodate the shock brackets and be able to use the original bolts. I can't find anything concerning the different grease baffles in writing or parts books other than Ford Barn thread search.

Re: Rear Backing Plate Bolts
What great answers. A perfect example from all respondents of how helpful replies can be.
Nobody said "look up the judging standards" or "do a search its been answered before" Also Interesting how I had to edit my own post here so it could not be misunderstood as sarcastic or snarky by accident!. I should have made this a new subject quoting the old post but I don't know how to do it on my tablet. SAJ in NZ Last edited by SAJ; 05-28-2018 at 05:30 PM.

Re: Rear Backing Plate Bolts
An aside note:
If you order the new baffles AND the new bolts from Berts you get the correct shorter bolt set that fits the newer stamped baffles. I had a set of the older baffles and had to find some of the old longer bolts in the "old bolt bucket". |

Re: Rear Backing Plate Bolts
I see another possible area of confusion here.
There are two different sets of bolts involved here as we discussed. 1. The long set for revision 1 baffles with the sleeves spot welded to the baffle. 2. The short set for new stamped revision without sleeves. EACH set has two bolts that are longer than the other two. https://parts.modelastore.com/show_Product.asp?ID=3157. In each set the longer bolts fasten the RADIUS arms to backing plate. |

Re: Rear Backing Plate Bolts
Dan,
I think the one's with the spacers crimped/tack welded on are e-28...left hand E-brake. I'm 99.9% sure. The fronts will be the same way....I think it goes with the early drums. Also,...the bolts are different lengths.....early vs. late.. |

Re: Rear Backing Plate Bolts
I agree with Dudley. I have an early front end (round mounting front spindles) that has the spacers attached to the grease baffles.

Re: Rear Backing Plate Bolts
Here's a photo of an early '28 rear grease baffle. Note the spacers behind the nuts.
I'm trying to figure out if I have this installed correctly; that's a different thread. |

Re: Rear Backing Plate Bolts
You have them inside out(too catch the oil and grease) AND it needs to be turned 90
degrees...so it drains out the hole in the backing plate.. |

Re: Rear Backing Plate Bolts
Thank you!
I got this car in boxes. And I'm finding a paucity of literature on details like this. |

Re: Rear Backing Plate Bolts
Early '28's didn't have a separate emergency brake system; the hand lever applied all four service brakes.
Because it was not a completely separate system from the service brakes, several states declared it illegal which is why Ford completely re-designed the brake system in mid-28. |

I thought there might be a reason there was no e-brake carrier....! Hard to imagine a vehicle without a separate e-brake but, well, it was a long time ago...
