I just want to rebuild the drum brakes it has, with all new lines and a dual res. master cylinder. All I seem to find are complete bolt in pedal assemblies with boosters, disc brakes, and a whole bunch of other junk I don't really need. I did find this adaptor from ECI, that seems to be what I am looking for. It can use either a Corvette master, or a 67-72 Mustang cylinder. I am assuming the 39-40 pedal assembly is a typo, and they meant 48-52 pickup? It is listed as the correct adaptor for 48-52 trucks. Has anyone used this adaptor, and did it work. I was thinking if I install this and all new lines/master/hardware/shoes, that I could at least test drive the truck to see if a new clutch is needed, and/or transmission work. 48-52 Ford P/U - Adapts EC-445 Mustang master cylinder to stock 39-40 pedal assembly. Includes hardware. Uses stock Ford pushrod and boot. EC-410A...............................................................$ 49.95 http://www.ecihotrodbrakes.com/ford_master_cylinder_systems.html
I donno about the master cylinder stuff but ya can rebuild your drum brakes useing 66 F100 hardware and have self adjusting brakes. There are a few threads about it on here
I've used the adapter, works great. I re-used the adapter when I converted to disc brakes. Used the Mustang cylinder. (Make sure you get the drum/drum MC if keeping your front drum brakes).
Excellent info, both of you. The sad part is that it looks like someone had replaced all the soft lines, but back far enough that they need replaced again. My brake was stuck hard, and one day I said to hell with it and pushed it as hard as I could. The floor hole was uncovered, and it still had the vented cap. When the pedal finally let go and hit the floor, I was greeted with a huge cloud of orange dust that shot up between my knees, lol!
I bought all my brake hardware, shoes, wheel cyls etc. from Napa, and it was very inexpensive. The only thing they don't sell is front drums.
Forgive my ignorance, new member here. I am looking to replace the original M/C (1952 F-1) with a dual M/C. is there a project page, how to or thread on the steps needed to make the conversion and do it right ? Thanx
ECI Hot Rod Brakes makes a bracket to mount a 67-72 mustang master cylinder in the original location. You'll just have to plumb the brake lines, and I believe you may need a 2# residual pressure valve in the lines going to the rear drums. I can't quite remember. Give ECI Hot Rod Brakes a call. Their tech people are a great help. *No, I am not a compensated spokesperson!
I really don't think there is any dire need to install anything but the original "stuff". I have a 52 F1 project that i'm doing right now. I just replaced the usual stuff and painted the frame back to the bed. Single MC's were used forever and I personally have never heard of a failure...one that would have been averted by a dual MC. Note: if you are going to screw up a nice truck with a belly button motor and try to drive 90 + well maybe you need that stuff. My 38 project has the same MC and I drive it all over @ speed. I never consider brake failure a viable possibility. Note the usual "stuff": Shoes, drums, springs, wheel cylinders, hard lines, MC, associated pedal bushings, pivot ball bushings and pins.
GreenMonster48, Thank you for the heads up. called eci ordered the adapter for the dual M/C. The 1967 mustang m/c, manual, drum/drum has the rpv integrated in the m/c Ford-truck..com a wealth of information. If you go to the thread,"1951 brake drums" The fellas are using 1986, Ford F-150 rear brake drums for the front drums for 48-52 Napa has them in stock, I am picking them up in the morning. 45.00 ea, that is better than 119.00 ea plus s/h. Gene, I like your style. I met my love in 93 and we have been together ever since. rebuilt the 239 all original stuff, oil bath air cleaner, horse hair seat, the vacuum windshield wipers..... We were out for a ride heading down to the park and I stepped on the brakes and the pedal went to the floor. I had no brakes and was freakin out. I put her in second gear and you know, I was not getting her into first.... We were traveling at about 20mph on a down hill grade and it was getting steeper.... I put her in a ditch and against a dirt berm. I still sweat when I think about that. Brake line rusted through, at the rear where the brake hose connects to the brake line.behind the flare nut. Took me two years before I could drive her again...... Dual reservoir M/C for me.
Well glad you and you gal are ok. My point is there were bazillions of cars made with single reservoir MC's probably every open wheel drag car has a single MC. My funny had front wheel brakes (NHRA mandate) and a single MC my fuel dragster had rear only brakes and a single MC. I'm sure somebody will chime in and say, "but you had a chute (s)" doesn't help much without brakes. Regardless it's not an imperative in a ride that is only going to go 60 MPH once a month.
the point about the dual mc is if one side fails you still have one side left. but it is still a little scary when it fails. the point gene makes is an execellant one. if you are rebuilding 60 year old system do everything, m/c w/c shoes, flex lines hard lines, make sure drums are within specs to be turned adj so there is some drag on them, new wheel bearings adjusted and your good to go. if the old truck is basically a stocker it will stop no problem, gene and I were in old school when it was grade school Tom
Sorry to necropost but such stories can grow(and have grown) until people are scared of things unnecessarily. That unfortunate brake failure was not due to a MC in any way. It was due to a rusted out brake line. I mean absolutely no offense but that is the result of poor maintenance. When putting a 72 yo vehicle(or in many cases even older) back on the road, a consideration of the brake lines should not be skipped. To restart an earlier discussion, I have heard that a dual MC will not save a failure of this type. I have never tested that. Is that true? D
