Steve,
It may depend on what car you've got but on my 07 +4 you can get some adjustment on the brake pedal by moving the clevis on the servo push rod. Loosen the clevis locknut. Take out the split pin and clevis pin. You can then screw the clevis further on to the servo push rod. Replace pin and split pin, then tighten the lock nut. This may be enough to get the brake pedal in line with the throttle. You may have to adjust the brake light switch afterwards.
Cheers
John
