1948 Ford brake issue

I have a 48 super deluxe and I have done all new parts in my front end. new shoes, wheel cylinders, retracting springs, and even drums. I am having an issue with a high spot and im not sure how to go about correcting it, when I spin the wheel it makes almost a full turn then stops, If i muscle it over it starts to spin again, now i have driven it about 20 miles or so and when I am stopping i get a little bump bump sound from the front drums and the pedal pulsates like crazy. so im guessing that i am only hitting the high spot on the shoes and nothing more. any suggestions? im guessing im gonna have to find the high spot and file it down until it matches the drum shape.

 

Take the drum/hub assembly to a brake shop and have them skim cut the drum. If it's a hard spot they may have to grind it, but better have it done on a lathe to keep things true.

Flatman

 

check to make sure the new drums are squarely mounted on the hubs , it may be cocked a bit .then turn slightly them as flatman said

 

If the drums are true have the shoes fitted by a brake shop.

 

You may have to hunt to find a shop that still has an arc grinding machine, but on a non-self energizing brake system like '39-'48 Fords have, arcing the shoes to fit the drum can make a real difference.

 

yes, arcing the shoes can help make the brakes work better , but the pulsating in the brake pedal is from an out of round condition on the drums

 

Belly up to the bar and get some new brake drums. No use fighting hard spots and ovaled drums. These things keep you from becoming a new bumper on diesel truck trailer or a back seat passenger in a VW GTI.

 

I have new drums on the car, still have an issue

 

If you have new drums, then you have one that is defective. Get it replaced. Manufacturing defects like hard spots make it a warranty issue.
