[FWDLK] Bellows or Canister?

[Dave Stragand <dave.stragand@xxxxxxxxxxx>]

Hi All,

 

I've always wondered about the power brake boosters... both bellows-type and canister type.

 

On my Plymouth, I've got a bellows-type I scavenged from a 1959 Chrysler.  But on recent trips to yards, I've seen canister-types on a 1959 Dodge, 1960 Imperial, and a 1957 Plymouth.

 

Every service manual I've seen only includes repair information on the bellows-type.  Was the bellows-type factory-installed, and the canister-type dealer-installed?  Any logic, pattern, or method as to which is correct for a given car, in a given year? 

 

Thanks for any info y'all might have,
