1968 PDB booster vs. Drum brake

Forsche · Jul 8, 2013

I'm looking for a power brake booster to replace the missing on on Sara's CS. Found one on Ebay and bought it and then remembered that I recall someone saying the PDB and power drum brake boosters are different? I'll try to take a pic of the one I have but can anyone tell me if the are different and how can I tell which One I have? Thanks.

No.because In stock configuration for the Mustang, or a Fairlane, there is no such thing as a Disc Brake, Booster, or a Drum Brake booster, all are the same for the particular year. So basically,a booster is a booster.
The "difference" is in the master cylinder bore. The Drum masters have a smaller bore (Measured in 32's if i remember correct), the Disc is a tiny bit bigger. In General fashion a Drum: 7/8 "---Disc brake :15/16-1" but NO Larger than a 1". Hope this helps

This does help! Thanks. I'll send it in to Booster Dewey to rebuild.
