brake upgrade questions ,Chrysler master cylinder..
I am posting a pic ,it appears my truck has a Chrysler master cylinder , no proportioning valve and of course it is still drum brakes all 4 corners.. My question is this , I know Chrysler master cylinder like this were used on drum brakes , but were they used without proportioning valves??
My son had a brake line start leaking , and of course he never noticed , so I go to move the truck and the pedal goes to the floor , it still had brakes ,but the front of the master cylinder was empty .rear line was leaking .... I am no Chrysler expert so I am hoping someone here is... |

Re: brake upgrade questions ,Chrysler master cylinder..
Never seen one with a Chrysler Master on it. But having done a conversion on my 64 & 65 from manual single pot master to manual dual pot (drum/drum) No proportioning valve is needed with the 67 and up C10 dual masters. Same is true for the C10 Drum/Drum power master....the proportioning is in master cylinder.
As I recall, you should not need a proportioning valve until you have a disc/drum set up. There are some smarter folks on here, they'll pop in directly. Last edited by Sharps40; 10-18-2013 at 08:46 PM. |

Well, all that said, if the back plum locks up and drags before the front and yer ass swings around in the other lane, then ya prolly need a proportioning valve for the rear line.

Re: brake upgrade questions ,Chrysler master cylinder..
No proportioning valve is needed for a drum/drum braking system. Just for the disc/drum and disc/disc systems.

Re: brake upgrade questions ,Chrysler master cylinder..
It always worked normal so I thought it was OK , that being said I do need to replace the line from the master cylinder because it has 2 compression fittings in it and I also need a new rear brake hose because it is the wrong one and it has no mount . and the crimps have rusted away ,they look too thin for my liking..so it is kind of floating around ... Hopefully my son learned about adjusting brakes and maintainance .. I hope...
