well this is a basic question, how much brake fluid is in the complete brake system on a early commodore??? i assume the vb-vl all have the same pipes etc and contain the same volume
about 1 litre .... so if you buy 2 500ml bottles you should be sweet. If you are starting off empty you might want an extra bottle cos you will use a bit more to bleed the system.
yer it should be completly empty, all calipers were off, master cylinder/booster was off so ruffly 1.5ltr or 3 of there 500ml pbr bottles cheers
