I dont see any advantage, my coupe stops fine with mechanical when adjusted properly. I could be wrong but those brakes are probly either on or off no in between. Brakes aren't ready something you try a sience experiment on to see if it works or not
We adjusted Model A brakes at work on a resto-the whole time I was thinkin:this thing needs juice brakes! Please dont try the electric brakes,
I don't see how that would help unless your conversion increases the brake area, and even then I'm not sure I'd want larger rear brakes than front...
You really only have two choices.... Rebuild the original mechanicals and keep them properly maintained....They work surprisingly well on a stock A...Providing you're not planning on pounding down the freeway. Of course a stock A is only good for about 45-50 anyway, so I doubt you'll be spending much time in the fast lane. Convert it to juice brakes using early Ford parts.... This has been done thousands of times, it's easy to do, and even the restoration crowd looks on the conversion as acceptable for touring cars(mostly). I wouldn't fool around with electric brakes. Try to stick with a tried and true modification and I think you'll be happier in the long run.
Soooo...let me get this straight. You think that rear wheel only electric brakes will offer better performance than the 4 wheel factory mechanical brakes? You realize that the front brakes do the major amount of braking in any car...correct? What you need to do is set a realistic goal in braking that matches the realistic speed capability of your A. If its stock you can get acceptable performance from overhauled original equipment. If its modded for additional speed and acceleration you should at least upgrade to hydraulic drum brakes all around. Early Ford or even 50's F1/F100 truck units can work. There is no advantage to what you're suggesting...just unnecessary complication.
Two words for mechanical brakes.... Flathead Ted. Google it. Go to media and watch the video and get your credit card out.
Electric trailer brakes are modulated with a brake controller in the towing vehicle BUT I say NO NO to using them on a car..... as was said, adjust the mechanicals properly and they will work well -- though you might want hydraulics if you are driving at today's highway speeds.
I drive a Model A pickup with mechanical brakes everyday and it will skid all four tires. They work fine if everything is in good condition and properly adjusted. You need to go completely thru them replacing any part that shows wear and install floater kits then they will adjust and work right. Early Ford hydraulic brakes work better but also need to be correctly rebuilt and adjusted.
I have just done the brakes on mine new cast drums flathead ted kit new rods redid kinkpins can lock up all 4 wheels on 16 inch wheels what more can you do other than ABS
No Electric Brakes. Stock Model "A"s have no problem stopping straight and quickly within the performance limitations of the stock Model"A"... Horsepower, weight & tire size.... In my opinion...
