Masuma brake calipers are manufactured in full compliance with OEM specifications, allowing them to be used as direct replacements for worn original components.
Housing
Depending on the vehicle application, Masuma caliper housings are made from two types of metal:
- QT450-10 — high-strength ductile iron with nodular graphite, widely used in the automotive industry for critical cast components. The spherical graphite structure enhances strength and ductility compared to conventional gray cast iron, providing excellent impact resistance and vibration durability.
- ZL101A — an aluminum-silicon alloy with magnesium. This casting alloy enables the production of complex, high-precision shapes. It offers an excellent strength-to-weight ratio and strong corrosion resistance, making it ideal for applications where reducing unsprung mass is important.
Pistons and Guide Pins
Steel pistons (Grade 20 steel) and guide pins (Grade 45 steel) provide long service life, corrosion resistance, and stable performance across a wide temperature range.
Dust Boots
EPDM rubber dust boots are resistant to aging, ozone, and aggressive environmental factors, effectively protecting internal caliper components from water and contaminants.
