Line lock question
 
I found a drop of fluid on the bottom of my line lock,right on the stud/nut at the center of the solenoid. It's clear and odorless,are they filled with a lubricant? Thanks.

They are filled with brake fluid if they are on a car. Is this a Hurst or a copy? You can buy a rebuild kit and replace the o-rings. You can also just replace the o-rings if you have a source for EPDM O-rings. Only use EPDM O-rings, don't ask how I know! I found what I needed in small packs on ebay so I can rebuild mine if needed.

Speaking of line-locks. Has anyone ever had a spongy pedal because of a line lock problem? Every single piece of the hydraulic system has been replaced except for the roll control and I still have a spongy pedal. It wil come around on the second stab and work great. I even installed a front disc conversion and went with a G.M. Corvette style master cylinder and still soft. Arrrgh!

Tommy,

what about the mounting position? Might it be mounted at a high point and be trapping air?

Its lower than the master cylinder but not by much. I am going to by-pass it tomorrow and see what I have.Thanks for the suggestion.

Well I by-passed the line lock and the problem is still there. Anyone run a residual valve on their car even if the master cylinder is higher than the calipers?

Tommy we had similar problem on a car we bought it had Strange brakes on the front and rear. On each caliper it has either 2 or 4 bleeders you need to bleed all of them. Also it had a Hurst line lock..We installed the rebuild kit and that fixed that problem.

Is the pedal ratio correct for the conversion/disc brakes?

Buy a couple of plugs that will fit the MC. Plug off 1 section and see what it feels like. If it's still spongy plug off the other and try it, spongy with both plugged you've got air in the MC. If plugging 1 section makes the pedal firm you have air in the section or a hose ballooning.

Thanks for the ideas guys. I like the idea about blocking off a chamber on the m/c and see what happens. The disc conversion company says to pick up the $30.00 Harbor Freight pressure bleeder and use it. Gonna try that tomorrow. I hear pedal ratio thrown around on other forums. Maybe I'm going to have to learn about that next. Thanks.
