One of my customers is in trouble & needs a power master new preferred or a good power motor to fix his. Up till now he's been supplying his own parts with rebuilt & gotten two bad ones in a row. So I did a conversion & that sucked the brakes just don't feel correct, I suspect that these engines just can't supply enough vacuum to keep the booster happy, I don't like to take a chance with brakes. have always been able to service the original ,Now the parts are getting scarce.Maybe it's time to start working on Subaru's, I hate hunting for parts, Anyone got any better ideas let me know. Thanks Lou
