Disc brakes from my parts car
I have a 72 Dart Swinger, 318 parts car that has a front disc brake setup. I was wondering if there is any reason I should not swap those brakes for the drum setup in my 72 Scamp? I understand they are not as large ast the 73 and up but I figure a bird in the hand, right? Can you convince me that i'm wrong?
Also - on a related issue, there is a mild cam in my 360 and apparently I'm not getting enough vacuum for the booster to work properly. I have to pump the brake a couple of times to get firm pedal. Is there a remedy for this?
Thanks for your help,
Gary
What are you trying to accomplish? The SBC drum to K-H disc is bolt-in.
You will have a very good improvement in braking with the K-H setup.
The 1965 - 72 Kelsey Hayes 4 piston caliper front disc brake setup works great when in good working order. There are caliper rebuild kits available as well as front pads and hardware.
SBC rotors are available from numerous sources, including O'Reillys, Napa, Advance, Summit as well as others.
Search this forum for all the parts numbers as well as sources.
Rotors (Centric, Wagner, Raybestos,Summit) are in the $40-92 range.
Calipers can be upgraded to stainless steel sleeved units for a reasonable price. The stainless piston bores are a rust-free lifetime upgrade and will work great. Try

Remember, if you go to the LBC 4.5" '73-76 A body disc setup, you will also have to change the rear axle bolt pattern to LBC/4.5", and either buy/use 4.5" LBC wheels.
By the time you add up all the costs required to go from the SBC to the LBC, it's not inexpensive.
Since you have the K-H setup, stick with it (works great on my '71 Duster 340) -- go for it.
If you did not have the K-H setup and had a drum setup, moving to LBC/4.5" is a no-brainer.
