SV: Re:: [Chrysler300] A serious 55 Kelsey Hayes issue - brake failure

["Narve Nordanger" <narve.n@xxxxxxx>]

A follow up:

I have now taken the set-up apart again and found to my dismay that the
actuating/push rod from the freshly overhauled MC measured close to 10? and
not the stated exact 8?61/64. If someone missed by 1? that be
rectified/readjusted, however the Shop Manual also talks about a Push Rod
Retainer Clip (Fig 79 in the SM) that according to the 55 Parts Manual is
only serviced as part of a service kit and has no separate Parts no. This
clip locks the Rod to the innards of the MC, making the MC and pedal action
conncted both directions (in and out, sort of desmodromic). 

 

Anyone got a clue for replacement, or possibly a spare? 

 

regards,

Subject: [Chrysler300] A serious 55 Kelsey Hayes issue - brake failure

Group,

my C-300 has twice this summer had failure on its freshly overhauled brake
system. On both occasions the Kelsey Hayes master power brake appear to lock
up and not letting out the vacuum after I have released the brake pedal.
Brakes stayed locked until I split the master cylinder from the booster.
Anyone seen this before, any remedy?

Additional information: The lightest of touches on the brake pedal sucks it
in and make immediate contact on the shoes, making progressive braking a
difficulty. This was evident both with the old (original) and overhauled
(x-55 De Soto) K-H MC. Having just gone through the brakes on 29 Chrysler
one really wonders if there was any progress at all in the intervening 26
years..
