Thanks for the replies! I believe the disc brake kit was from the INLINE TUBE COMPANY. I got the kit around 2000 or 2001. I can not find the papers that came with the kit. They did include with the front disc brake kit a master cylinder that would be a match for my needs. I used the original proportioning valve that was on my car, which had drum brakes front and rear. Were proportioning valves different for rear drum, front disc brake applications than for drums front and rear? If so, where can I get the correct one? Thanks again for the replies so far!
