Wilwood 120-9333 GM Metric Iron Brake Caliper Piston - 2.00 D154

The Wilwood 120-9333 is a high-quality GM Metric iron single piston floating caliper designed as a direct bolt-on replacement for 1978 and later GM Metric calipers. Featuring a 2.00" diameter stainless steel piston, this caliper is ideal for spec racing categories and cost-effective disc brake conversions where precise brake bias tuning is essential.

Key Features:

• 2.00" diameter stainless steel piston for optimal brake bias tuning
• Purpose-built casting specifically designed for 2.00" bore size—not a re-machined OE caliper
• Stainless steel piston resists corrosion and reduces heat transfer from brake pads
• High-temperature bore seals provide extended service life and positive piston retraction
• Direct bolt-on replacement for 1978-later GM Metric calipers
• Compatible with standard D154 type brake pads
• Optimized casting design for strength without unnecessary weight

Performance Benefits:

Wilwood engineered three distinct GM Metric caliper castings (available in 2.00", 2.50", and 2.75" bore sizes) to give builders the ability to properly tune static brake bias front-to-rear. Unlike re-machined OE calipers that compromise structural integrity, each Wilwood casting is precision-designed for its specific piston diameter, ensuring maximum strength, reliability, and performance. The stainless steel piston construction resists corrosion while slowing heat transfer, and the high-temperature seals maintain their resilience even under hard braking conditions.

This caliper accepts the complete range of Wilwood D154 high-performance and racing brake pad compounds, allowing you to match friction characteristics, response, and temperature range to your specific application requirements.
