RE: {Chrysler 300} Brake Booster Accordions

Josh – Do any just say Kelsey Hayes without the 1675213 or C-57 designation ? That may be the one with the double fork.

Thanks for the input. Most of them say “Do not lubricate or undercoating this unit”. Followed by 1675213 with C-57 under that. Opposite end does have Kelsey Hayes on it too.

Kelsey-Hayes supplied boosters to other makes besides Chrysler Corp. So some of the components were slightly different. Check the stamped plate on the front. Does it say Chrysler on it, or is it blank ?

Hello everyone,

I have some 1957-58 brake booster accordions available if anyone is interested. They all seem to be the same, except one has a shorter mounting bracket, plus the fork out the back has four fingers instead of two. Can anyone explain this difference? Let me know if you need one.

Thanks,
Josh Mishler
