Frequently Asked Questions
Q: What is the difference between BR B19121-1 and BR B19121-001?
A: BR B19121-1 and BR B19121-001 are related part numbers for master cylinders. Both feature 1.00 inch bore and ductile iron construction. BR B19121-1 supersedes earlier versions including BR19121-001-ORG and BR19121-007. Use the exact part number specified in your equipment documentation.
Q: What are the compatible cross-reference numbers for the BR B19121-1 master cylinder?
A: The BR B19121-1 cross-references to BR19121-001-ORG, BR19121-007, and equivalent B19121-4. This master cylinder supersedes and replaces previous Barrett cylinder part numbers. If your equipment requires any of these numbers, the BR B19121-1 is a current replacement part.
Q: Is the BR B19121-1 compatible with Crown electric lift trucks?
A: The BR B19121-1 master cylinder with 1.00 inch bore and ductile iron body may fit Crown electric lift trucks using standard hydraulic brake systems. Cross-reference your Crown model documentation with the BR B19121-1 specifications to confirm compatibility.
Q: What hydraulic fluid pressure rating should the BR B19121-1 master cylinder handle?
A: The BR B19121-1 is designed for typical electric lift truck brake circuit pressures. Standard hydraulic brake systems operate between 500 and 1500 PSI depending on system design. Verify your equipment manual for correct pressure specifications and fluid type compatibility.
Q: What materials is the BR B19121-1 made from?
A: The BR B19121-1 features a ductile iron body, which provides strength and durability in hydraulic brake systems. Ductile iron resists corrosion and handles cyclic brake pressure loads effectively. Internal seals and pistons are designed for long-term hydraulic compatibility.
Q: How do I diagnose a failing BR B19121-1 master cylinder?
A: Symptoms of master cylinder failure include soft or spongy brake pedal, fluid leakage around the cylinder, and inconsistent braking pressure. If hydraulic fluid becomes contaminated or seals deteriorate, the master cylinder should be replaced. Check hydraulic fluid condition regularly and maintain system cleanliness.
