Default Re: Juice brakes

Here's my setup. Only had this car a couple weeks and got it running for first time in many years. Now on to the brakes These are 39-48 Ford brakes. Pulled the rear drum (first photo) and the rear backing plate bolts right up to a Model A rear axle. 12" drums in second photo. Front brakes in third photo. The front spindle is from a 39-48 Ford. Model A front spindles won't work without adapters, as others have stated above. Next two photos are the master cylinder mounted up against the bottom of the frame. It's nearly impossible to access for adding fluid. The original service brake cross shaft is cleverly used to run the push rod for the master cylinder. Last photo are the copper brake lines. Yikes!! Those will need to go.

My conclusion: Model A's have 11" brake drums. These later hydraulic drums are 12", designed to stop a much heavier car than a Model A, so these babies will stop an A on dime and give you 8 cents change.
Vernlee: Hopefully you can figure out a better mounting setup for your master cylinder that will give you better access for fluid. The rest is fairly straight forward. Good luck with your project!
PS- If the car wasn't already set up with juice brakes, I would't dream of converting. But since it is, it's a fun adventure.
