p0172 system to rich bank 1
p0440 Evaporative Emissions failure

code p 0440 refers to evaporative emission (EVAP) system---malfunction===causes ---hose connections ---intake leak---EVAP canister purge valve
probably the purge valve needs replacing

code p 0172 refers to system too lean, bank 1===causes --intake blocked , EVAP canister purge valve ---fuel pressure ---EGR system---injector/s HO2S
you will notice that the purge valve is in both codes and it also affects the fuel pressure by not venting the tank correctly
That will account for the fuel pressure problem

To fix the E brake you have to take the cover off that surrounds the brake lever and behind it is a nut on a cable attached to two other cables with a single nut is your adjuster, tighten it up till the handle is about half way up to fully lock the rear wheels. If the adjuster is all the way back and still can't hold the car then your rear brakes are worn out, replace asap. As for your codes just call up any vdub dealer and ask them to tell you what the codes mean.
