does anyone know if there is a vacumme line that is supposed to be hooked to the brake system? if so, where is it? my brakes haven't worked correctly since having my longtubes installed. there is also a vac. leak that i can't find.
brakes are assisted by the powersteering on the 4.6 GTs , no vacuum to booster to worry about , check the AIR tube fitting for a leak there , otherwise it leaking somewhere else , probably not related to your long tubes , as far as brakes go , make sure you didnt damage any of the lines below the master cylinder and try bleeding the system and go from there .
