Caliso 121-66004 C-Tek Standard Front Disc Brake Rotor

The Caliso 121-66004 is a C-Tek Standard front disc brake rotor engineered to meet original equipment specifications using proven OE production processes. Designed as a direct-fit replacement for worn or damaged front rotors, this economy-grade disc rotor delivers reliable, safe stopping performance without compromising on quality.

Built to QS and ISO quality system standards, this rotor is manufactured using advanced metallurgy to minimize brake squeal and deliver consistent pedal feel. The non-directional friction surface finish simplifies bed-in and promotes even pad seating right from installation.

Key Features:

• Engineered to OE specifications for a precise, original-fit replacement
• Double disc ground friction surface prevents run-out and ensures parallelism for optimal disc thickness variation
• Non-directional surface finish promotes faster, more even brake pad break-in
• Precision-machined non-friction surfaces improve rotor balance and appearance
• Manufactured to QS and ISO quality system standards
• Economy grade — ideal for daily drivers and budget-conscious repairs
• Non-coated finish

Also commonly referenced as part number 121.66004. This front disc brake rotor is a straightforward, cost-effective solution for restoring safe braking performance.
