Brake System Flush
Posted: Fri Dec 22, 2006 3:07 pm
Just going over my '94 to make sure she's ready for inspection, and I've realized that my brake fluid is nearly black - I'm planning on power-bleeding the whole system in the spring, but with that much crap in the lines, I'm wondering if anyone has had any experience using some kind of a solvent to "flush out" the lines instead of just replacing the old fluid with new in one operation? I'm worried that a lot of this stuff will adhere to the inside of the lines and quickly recontaminate the new fluid.
My first thought is to disconnect each line at the ABS valve body and flush it with ordinary parts washer solvent (not worried about the rubber parts downstream, they're all being replaced as well), but I'm curious if anyone else has any suggestions, or if this would be overkill in anyone's experience.
Also, does anyone know of a non-ABS master cylinder that will (more or less) bolt into this application? I noticed a loss in pedal feel when I disconnected the ABS solenoids a year or so ago (something was causing the system to release my brakes randomly while waiting at red lights...not a fan of ABS anyway, so I just disconnected it to fault out the system) and I'd like to take this opportunity to tighten things back up. It's not so bad that I'd call it a safety concern, but it really does detract from the precise, "controlled" feel of the car.
Any advice is appreciated!
