Kraus, RTX8 Radial Brake Caliper. Right. Black
The Kraus RTX8 caliper is engineered for sustained; high-performance braking; featuring a five-bolt design that maximizes stability under load. Built for extended use; its two-piece construction integrates a finned backing to enhance heat dissipation; while four stainless steel pistons regulate thermal transfer to keep brake fluid temperatures steady. The upgrade to radial brake calipers requires a radial caliper mounting bracket. These are separately available for a straightforward transition. Kraus or Öhlins inverted fork kits with 108mm radial caliper fitment will allow a direct installation. OK for ABS; right?- Includes Kraus RT-S sintered Street Pads - Optional Kraus Performance and Race Pads available - Better lever feel - Strong; consistent braking - Road-Legal race caliper - Finned 2-piece caliper design for optimal heat dissipation - CNC machined race-grade alloy billet aluminum - 748 gram lightweight; 27% lighter than stock - Pre-Bled* for easy installation - Easy adjustable for different rotor sizes with optional stackable caliper spacers*Note: Final bleeding procedure required for optimal performance. Each caliper is pre-bled in-house; though a confirmation bleed is still necessary. Kraus incorporated an outboard bleed nipple and banjo take-off; making bleeding and installation easier while allowing fluid to fully circulate the caliper.Note: Installation hardware is not included; See 985741 for G5 titanium radial caliper hardware kit.
