Technical BRAKES..........F100 brakes on 37 to 48 Ford spindles..

sticky out bit?


p.s.

do they have a crush washer or something?

 

Most front cylinders use copper crush washers.

Pictures are later square back spindles but; gives you the idea.

 

are they 16'' f1 wheels?

 

15" F-100 wheels (later outside hub cap bump version)

 

was looking at wheels, and caps,
is it 69-91
all caps the same fitment?

oh i see
56 is 9.5''
later 10.5

 

Silly question.. will F-100 backing plates bolt up to model a spindles or do you need to use the 37?-48 spindles.

 

The bolt pattern on the earlier spindle is smaller than the 37-48.I have seen guys slot the backing plate holes to use them,but the cleaner fix is weld the holes shut,and redrill to the smaller pattern.You may need the centering ring for the center hole,but most early Ford parts suppliers have that.

 

"Juice brake" kit, slotted or welded & re-drilled holes (which still end up open on one edge as in the one picture).

 

Heres the parts I used

Tech suggestion - Make a simple shouldered arbor/spindle that will press part way into the opposite side of the bearing, this will allow you to spin the bearing in a lathe or drill whilst grinding the radius ...... makes for a much more consistent radius/result.
BTW, Rich graciously helped me immensely with my F2/Buick drum front brake conversion, I'm forever grateful for his ***istance.

 

Used a piston ring for a spacer on my A.

 

Been keeping up with this thread , good info , I got my 53 F100 front brakes on my 31 model a all done , got my master cylinder mounted and front brake lines run so far so good , BUT what about the rear brakes ? I got my 53 f100 backing plates - brake drums - brake shoes and all hardware ready to go and there's no way under the sun any of this is going to fit the stock rear model a ? now what ? what are my options without spending 1000's of dollars , what backing plates will work / what drums ? can I keep my front self energizing front brakes and not have SE on the rear ? . There is tons of info for the front brakes but hardly nothing for the rear hydraulic conversion , I'm super bummed right now .

 

'42-'48 Lockheed brakes work. You have to rotate them back a little to clear the shock mount and maybe shave a bit off the backing plate lip so the drum doesn't rub. Some people mount them upside down.

If you want to spend more; Boling Bros Lincoln repop set-up for A's work.

If you're feeling ambitious; a liitle fabrication and machine work you can fit F-1/F-100 front plates, most any 11" e-brake hardware, '40 rear hubs, and Bronco drums to your A rear.

Lockheed brakes would probably be adequate in most cases.

 

Post quoted above is #34 post on page #2
These parts do not fit the Speedway 40's hub they sell part #91065450. You will have to call them and order the correct bearings and seals. It saves you about 40 bucks over their $121.99 dollar kit Part #91065455

The Correct part numbers from them are as follows.
Front Inner Bearing Part # 912T15118
Front Outer Bearing Part # 912T09074
Seal Part # 912S48190

I have called Speedway to ask them to offer these parts as a kit over the other one since you don't need the bearing races. The races are already pressed into their hubs.

 

why does the hub get narrower on the f100 from f1
is it because they go to 15'' wheels?
-the king pin incline changes?

 

The discussion was regarding F-1/F-100 brake swap and the bearings I posted are relevant to those hubs not early Ford or Speedway's repop hubs.

Easy enough to drop Speedy's prefix and get real bearings; tho the seal number is odd, unless Speedy's hubs use a non standard seal.

 

Yes, Ford changed the king pin angle in '53 and moved the flange inward to match. Don't know that it was do to tire size as Ford still used the same axle and spindles on F-250 etc which used larger wheels.

 

damn the rock auto sold out of brake lines and seals!!
oh dear!

is there a cross referencing alternative?

 

I used Raybestos brake hoses BH16179 for both sides. They work with the Original 39 to 48 front banjo fitting or 1/4 inch brake lines. The original application was for a 52 to 54 ford p*** car, i believe rear brake hose. works perfect on my 39 with F100 brakes.

 

Good info; it's also my go to hose for 1/4" lines; the hose is 15-3/8” long, 3/8x24 male & 7/16-24 female.

If you are using smaller 3/16” lines, a BH84517 may work for you. 16” long, 3/8x24 male & female.

If you have need of a longer hose, a BH58536 is 23” long, 3/8x24 male & female.

I need a 21" hose, but with 7/16x24 female & 3/8x24 male, do you happen to know a part number for that?

If you come up with a hose; please share the number here.

If you don't have any luck finding a hose and are not adverse to adapters you could use an Edelmann 258430 3/16" male inverted flare to 1/4" female inverted flare fitting to use the 3/8 x 3/8 hose.

Another option: Brake & Equipment in MPLS. I've had hoses made there in the past.

Could use some help. These are the two inner bearings that I pulled from the F-100 hubs being used in conjunction with the square back spindles that are on my model A. I just bought this car. I've never driven it. It's an "old" hot rod that I'm going thru to make sure it's road worthy. As you can see these bearing...though different...both have the part number 14120 not 14116 as referenced as the correct bearing to use for this conversion. I am ***uming (shame on me) that the races that are installed are for the 14120 bearings. Does anyone have an answer as to why this choice would have been made instead of using 14116 bearings? P.S. This isn't the first and probably won't be the last thing that I'll be scratching my head on as I'm digging in to this car. Thanks for your help.

Do those 14120 bearings have a large bevel on the other side?

14116:

R in pics. 14116 small Radius [.030], 14120 large Radius [.170]. Large radius to put F1 hubs on P*** square back spindles. Can use the 14116 but have to increase radius [lathe grinding wheels] to seat fully, put a bearing and you will see seating "face".

 

I'd consider these bevels to be small. Thanks for your help with this. You are a wealth of knowledge.

 

With the lazer printed part number on the back of one..it's clear that at least that bearing was installed in the modern era.
