Expert Installation Note: Maximizing Brake Pedal Feel and Longevity
Experience Tip: Whether installing on a classic vehicle or a piece of industrial equipment, ensure the pushrod length and linkage alignment are correct. Improper adjustment is the leading cause of spongy brake pedal feel due to seal damage. Our master cylinder features a specially honed bore to resist wear, ensuring your new seals last longer when paired with proper installation.
⚠ CRITICAL: Verify Bore Size Before Purchasing
To ensure proper vehicle braking pressure and safety, it is absolutely critical to physically verify that this master cylinder’s 1-inch bore size and 7/16″-24 outlet size match your existing unit. This specification determines the hydraulic displacement and must be accurate for proper automotive braking function.
