Same thing I said, based on low pedal, way back..I think Don is right..you have a manual brake master cylinder in there ; I think they have narrower bore and longer stroke, to get same CC it moves more, but as I said in other email, brake pedal mechanical ratio is also different on parts under dash. Thing must stop on a dime , with power working a manual cylinder! But more travel gives low pedal with low ratio power pedaI ; I had other problem, apparently (later dual) power master with 60 power pedal and no booster; unbelievably hard to stop car but pedal hardly moved. Cannot mix and match. Did not know what Don adds,---- thought it was variants among suppliers, have seen both types ; I changed pedal ratio but (accidently, knowing this) kept power master, with higher ratio pedal, works ok, a little stiff. Do not have info handy, but check various bores. Looks the same outside . Apparently same thing on dual MC too .Good to know about all this From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of 'Don Verity' d.verity@xxxxxxx [Chrysler300] Hi Terry, Wrong master cylinder. Sounds like one for a manual brake car. You can only get them out with the unit in a vise. Sent: Thursday, July 31, 2014 8:23 PM Subject: [Chrysler300] 300F Brakes Again! Terry McTaggart here in Dayton OH. New wheel cylinders, new master cylinder, new fluid, linings are great, all done by my local shop. And I myself jacked the car up and adjusted all the brakes. Car stops fine, but the pedal is low. Shop manual says the adjustment for this is the pushrod from the brake assembly thru the firewall into the master cylinder. But my car has a one-piece push rod, so there is no adjustment. So Murray Park sent me the correct two-piece pushrod. Inside the car, I disconnected the current pushrod from the brake pedal, but when I attempted to slide the pushrod out, it would not come out, even when I used considerable force. Looking at the manual, it should just slide out. Anybody got any ideas as to why it won't come out? __._,_.___ Posted by: "John Grady" <jkg@xxxxxxxxxxxxxxxxx> To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang __,_._,___ |
