| Post subject: | dual master cylinder for front discs |
I am using a dual master cylinder for the brakes on my mudbogger. Each resevoir feeds one front caliper. (no rear brakes) I wanted the safety of 2 separate brake circuits. The small side bled easily and works fine,,,but the large side is always soggy. Am I missing something? |

Soggy? Specify. Could be a residual pressure valve issue? But, that would be worse on the small (front) reservoir it seems. Is this a drum-drum MC? Lou |

It is supposedly a Corvette manual M/C for 4 wheel discs (66-76?)......but the local NAPA had it on the shelf.....Its more likely a truck manual cyl Its been on the car a couple of years....bled to death. Stops fine...but the pedal is soft. |

If it was sitting on the shelf for years it probably has an internal leak. The seals may have stuck in the bore and ripped the edge. |

Also, if we're talking about two reservoirs of unequal size, that suggests to me that it's a disc/drum master. Many of those have different hydraulic characteristics in the front/rear sections. If yours has such differences, I would think that could create a weird/soft pedal. |
