Rear Disc Brake Conversion Kit – Suits VB–VS Commodore & Custom 9”/Big Bearing Diffs | VT–VZ Brake Upgrade Compatible | Lowe Fabrication

The Lowe Fabrication Rear Disc Brake Conversion Kit is the ultimate solution for anyone looking to bring modern VT–VZ braking performance to early Commodore platforms or custom rear end setups.

Originally developed as the heart of our rear brake upgrade kit for VB–VS solid axle Commodores, this system has since become a favourite among builders, modifiers, and restorers upgrading early Borg Warner drum brakes — and those running custom 9” diffs or big bearing conversions.

No more stuffing around with mismatched handbrake systems or dodgy brackets — this is the clean, safe, and engineer-friendly solution that just works.

What’s Included:

• CNC-cut backing plates to suit Borg Warner live axle, 9″, or big bearing diff ends (choose your option)

• Brand new handbrake mechanisms

• New handbrake cable, ready to install

• Billet caliper bracket to suit VT–VZ rear calipers

• All components are brand new, high quality, and backed by warranty

• Optional: Slotted VT rotors & powder-coated rebuilt calipers (sold separately)
