Hydro-boost

Brakes always had a fair travel and needed a lot of force to haul the car up. The brake system couldn't lock the wheels and so the engineer wanted to see something better.

The disc brake conversion came with 1" bore master and 9" dia single diaphragm booster.

Swapped the booster for a dual diaphragm 8"... no dice.

Ended up going for a 1 1/8" bore master to reduce the stroke and a Hydro-boost brake booster to give the extra "oomph" required...




Made up high pressure hoses using Speedflow AN-6 fittings and Speedflow high pressure power steering hose...




Installed...




Wow! Chalk and cheese!

Standing on the brakes will lock all four tyres now. It has transformed the car and the engineer is well happy.

For anyone going to 4-wheel discs on an Amercian full-size, don't muck around with vacuum boosters... go with a Hydro-boost unit.

Air Filter Shroud

Next on the list in the quest to satisfy the engineer... shroud over the pod filter.

In NSW, we need to create a shield around the air filter to prevent any petrol fumes in the engine bay being ignited by the flames of a back-fire.

The Impala (being the tank that it is) had plenty of space to route the intake and to fit the pod filter in the front left corner of the engine bay. So all we needed to do was fold up some gal sheet to enclose said corner of the bay.

Time to get the carboard out...




Then the steel version...




Rivnuts are my new best friends... brilliant for this sort of work.




Test fit...




Then paint (satin black of course) and final fit...
