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.
