Eric, I'm assuming the alve body was installed by someone familier with this type of valvebody , and the servo plug and gov feed plug have been installed in the case. ..The modulator valve modifications and valve phasing are critical to the proper opperation of the brake....I've done at least a dozen of these brakes ,and have not had any problems with them. ........when all else fails ,call Hipster, and hang on! ..............Tom
