Need a quality brake upgrade?
The Hoppers Stoppers Billet HS4000 Compact 4 Piston Caliper brake package is designed to replace the factory PBR/Girling/Lock caliper as a direct bolt on, whilst still retaining the factory disc and still fitting within a factory 14” steel wheel.
The PBR/Girling/Girlock calipers are common to Holden HQ
