Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The large 1-3/4-inch bore is critical for maximizing fluid displacement to large wheel cylinders or calipers. When installing this unit, ensure your bleed procedure is thorough to remove all air from the extensive lines, which is the most common cause of a spongy pedal in high-volume commercial systems.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-3/4-inch bore size and three (3) 1/2-20 outlets match your existing unit before purchasing.
