GM Metric Brake Calipers

Wilwood's GM Metric Brake Caliper is a direct replacement for the 1978 and later D154 type GM metric caliper. Weighing in at a mere 2.97 pounds, it provides a substantial weight savings over cast iron OE calipers.

This high performance competition brake caliper represents the latest refinements in caliper design and manufacturing through the use of computer based FEA solid modeling and stress simulation programs. The real strength of this caliper comes from its triple bridge configuration, and its lightness is a result of efficient design.

The triple bridge provides higher clamping efficiency through lower deflection over all twin bridge models. All load bearing and stress points are fortified to maximize strength, and all unnecessary material is removed to maximize weight reduction. The results are the strongest, lightest, and most efficient aluminum brake calipers in their class.
