66 f100 front brake woes

[maddogjohnson]

I've been on countless forms read a ton of threads and have yet to see anything along these lines. I have a 1966 F-100 with a 1976 Buick 455 motor that a previous owner put into it. (Yeah, it took a few hours to figure out the motor as I grew up working on 65/66 Mustangs) I've got drums all around and have run into a few things that stump me.

1 - Wheel cylinders: Rear no problems, but the front cylinders took about 5 trips to various parts stores with the old cylinder before I found a match. It took finding a knowledgeable chap at a local Napa to end that saga. The part numbers for the cylinders that I've ended up starting to install are Napa 36057 and 36058 on the box and 18292/18293 stamped on the cylinder itself. These appear to be for a 91-93 Dodge D250/350. 9Just found that while writing this post)

The cylinders I pulled off the truck had a short 3/8 thread with a standard flare, while most replacements from shops had long/deep thread with a non-standard flare (unsure of the actual name). The the old cylinders have a lip inside for the standard flare to match up to while most replacements I was shown were deep thread with no lip inside. Which are correct? Do BrakeBest part numbers WC41718/WC41719 sound more like the correct replacement cylinder numbers for your typical 66 F-100?

2 - Brake Shoe Width: From what I have read, the shoes are supposed to be 11x2. The shoes I have removed from the front are a full 3" wide. 2" replacements won't work because they won't even touch the backing plate. Based on what I just found out about the wheel cylinders I think that I'd have to go with Napa part AE-358R to replace what I've got now.

3- Drum: My passenger drum has a stamp of max diameter 11.090 with these numbers as well, 3H11 and 212093-C 180 degrees opposite of each other, and WF 180 degrees opposite of the 11.090. Does this ring a bell or seem wrong?

4 - Backing Plate: My backing plates are FoMoCo and I see a part number 321394L on the drivers side. I can't see a number on passenger side. Is this a correct part number for this truck?

It looks like I have early 90's rear dodge brake components on the front of the truck. I feel like I'm working on franken-truck. What insight can anyone provide to the above? Thanks.

18292/18293 and 212093-C I believe are Wagner brake part numbers. I am not sure about the flairs thou different right and left cylinders is typical Ford. sorry not much help
Welcome to the Board hopefully someone will chime in more info

P.O.'s....ya GOTTA love 'em.

3" shoes were on some of the chrysler products, as well the rear of some 3/4 & 1 ton fords. The wheel cylinders might fit a dodge, but if you can get your Napa guy to let you look thru a brake parts illustratred catalog, or a buyers guide, you might find the cyl's fit a number if things.

IIRC, Napa brake parts are BPI (raybestos) Most of the base part #s are the came, prefix changes.

If i were you, i'd develop a good relationship with your napa guy
At this point, cataolgs & buyers guide's are your friends

My '69 F-100 has 3" wide front shoes, or had, it has discs now. I think Ford went to 3" shoes on the front in '68.

Might be a case for a front disk brake upgrade!!

If I had plans to keep the truck I'd do the front disk upgrade, but I don't think I'll have it for too long.

Since some 68/69's have 3" shoes I'll take my old one's into the parts store to see what they can match up. In fact, it looks like the Napa & Autozone part number online for a 69 F-100 matches up to the part number stamped on my shoes "265." Thanks for the responses!
