Disc brake conversion
I want to convert to front and rear disc brakes on my 51 f1. I am thinking of using the Speedway kit for the fronts and I am searching for a kit for the rears. Any help or suggestions is greatly appreciated.

Re: Disc brake conversion
Before someone tells you to go to the HAMB, try Google for "Rear Disc Brake Kits."

Re: Disc brake conversion
If you click on the "Hot Rods and Customs" forum it will take you to HAMB. You will be more likely to get your answer there.

Re: Disc brake conversion
I just finished installing an ECI kit on a 42 front axel. The problems were as follows. The Press fit was .004" and driving the bearing adapter with a piece of pipe with a BFH didn't work. So I warmed up the adapter with a torch and it went right on. The second problem came when I tried to install the bearing. The adapter had grown by .002" and ther wasn't any way to remove it so I spent an hour with some 80 grit emery bringing it down to size. Next problem was the filit radius of the adapter was too lard for the bearing and it wouldn't seat properly. I solved that problem with a small chain saw file to reduce the radius. This problem may have been caused by the Chinese bearings. I haven't solved the last problem yet and that's the seal doesn't fit the adapter, too small all these bearings and seals were bought new from the local parts store including the rotors. I still have the passenger side to do so Iturned the diam of the adapter down .002" and reduced the fillit radius to half the size. Still thnking about the seal.
Last but not least the Ford washer is too larg and has to be turned down, not sure how to do this yet. Now I have to find a grease seal. I hope this doesn't deter anyone from installing disk brakes on your early ford. |

I have installed several of their kits and have them on my car. The thing I like about them is, THEY FIT, right out of the box. No machine work, heat or diddling with parts to get them to fit. Their stuff looks like aero space quality also, not something made by kids in a tent in the middle of a rice paddy. |

I installed the ECI kit on my '49 front, only requiring a slight preheat of the adapter with a propane torch......Bob L

Re: Disc brake conversion
It must be me then and my chinese bearings. I know one rthing that's fact, after driving on ther adapter you couldn't get the bearing on with out reducing the size of the adapter. I measures it and there was a .002 interface.

Re: Disc brake conversion
I used the ECI kit this past summer. Went on fine. I had to take the spindles down just a hair with emery cloth to get the adapter to slide on.
Not sure I'd bother converting to rear discs unless you're building a superfast street machine. I suppose you know that they don't make a disc kit for the stock F1 rear. |

Re: Disc brake conversion
Going to discs in the rear is a lot of work and basically "overkill' on your old Ford. Put a power booster on your pedal assembly with the front discs and that will be all you need to stop on a dime.

Re: Disc brake conversion
I would imagine that with discs on the back of a pickup, you'd absolutely need a proportioning valve. To stop them locking up with an empty truck, maybe wound so far as to deem the discs no better than the drums.

Re: Disc brake conversion
For those that used the conversion, are you sure the bearing was flush against the shoulder of the adapter. Probably wouldn' hurt if it didn't. Now that I think of it, I should have honed the inside of the adapter to the Ford spindle size. I tried driving it in with a 3 lb hand sledge and it just didn't want to go more than 1/2 way. ECI should make it the same size as the Ford bearing. I'm still not sure of the seal I bought and will go back to the auto store and check if I have the right one. I've been told the stock grese cap doesn't fit either. OH Well, learn sumpin every day.

I remember looking hard at the adapter after I put it on the spindle to guarantee it was all the way on. There was just a little bit of space between the adapter and the shoulder, but it just wouldn't go on any further. Everything seems tight and I've put probably 100 miles on since the swap. |

Re: Disc brake conversion
I just ordered the basic kit from ECI for my 1939 ford pickup. They told I can't use my original wheels any more with this conversion. Can any one please tell me what wheels I should be using. I have 5 1/2 lug pattern. Is it a newer ford model wheel?
thanks. |
