Brake Pads 1978-88 GM Metric

The Brake Pads 1978-88 GM Metric from Allstar Performance represent a proven solution for classic GM muscle car restoration and performance brake upgrades. Engineered for the GM metric caliper systems found on first-generation Mustang II front brake conversions, these pads deliver reliable stopping power in street, strip, and vintage racing applications. Whether you're rebuilding a 1978–1988 Chevrolet, Pontiac, or Oldsmobile with modern braking capabilities, these metric-spec pads ensure proper fit, consistent engagement, and fade resistance across a wide range of driving conditions.

Sold as a complete set of four pads, these friction materials are formulated to match the thermal and pressure characteristics of GM metric calipers, ensuring predictable pedal modulation and reduced brake lag during hard stops. The compound resists glazing under sustained heat and maintains mechanical grip across temperature swings—critical for vehicles running on vintage suspension geometry where brake feel must be precise. Proper caliper alignment and rotor surface condition are essential; these pads perform optimally when installed on true, well-prepared rotors and verified for correct pad-to-rotor clearance, especially in retrofit applications where fitment tolerances can be tight.

Restorers and performance enthusiasts upgrading 1970s and 1980s GM vehicles benefit most from this set, particularly those installing Mustang II or modern GM metric brake kits to replace drum or single-piston systems. Installation requires correct caliper hardware and verified rotor diameter; cross-reference your specific vehicle's caliper casting number before ordering. The 3.35 lb pad set is compact enough for easy handling during installation while delivering the mass required for consistent thermal stability during aggressive braking cycles. Confirm metric caliper compatibility with your brake kit documentation to ensure seamless fitment and optimal safety margins.
