2004-2007 Cadillac CTS-V Performance Mods Discussion, ls7 Clutch swap trouble bleeding clutch!! in Cadillac CTS-V Series Forum - 2004 - 2007; True, you can bench bleed on the car. Just make sure you retain the TOB with a clamp or something ...
Maybe the slave is over extending. Is the friction plate in backwards or some spacer incorrect? If the slave is leaking it may be pushing too far out.
Also I heard about a Honda where the clutch pedal bracket was cracked. It would never make pressure because the master was not traveling enough.
Would one of those cameras on a stick fit in the hole on the side so you could perk in there while someone press the pedal?
On this topic, is the master something that should be done with a clutch swap? The LS7 swap is in my distant future, but didn't plan on replacing the master cylinder as well... Do these fail often or at any particular mileage? Are there any telltale signs of wear?
Nice. Good shop to help you out.
I have heard of masters failing after being bled, moved or transplanted to another vehicle. I think a weak seal can go when the piston suddenly travels in air not fluid during bleeding. Plus all the silt from the bottom of the reservoir get pushed through.
