Calipers and rotors bolt up cleanly once the Scarebird brackets are installed, using the existing Fit hub and the four original backing-plate bolts. Extras required beyond the brakes themselves: the Scarebird brackets; Integra parking-brake arms and mounting bolts (43267-SH3-931 left arm, 43247-SH3-931 right arm, 45240-SC2-003 bolts); 1987 Legend parking-brake cables with holding pin 43471-SD2-930 and cotter pin 90705-SD2-931; and conversion brake lines. ABS function is unaffected and no master-cylinder change is needed. FastBrakes now sells parking-brake cable adapters that allow the factory Fit cables to be retained, which avoids sourcing the Legend cables and grinding the floor slots.
The Integra rear calipers and rotors do not bolt directly to the Fit axle; they mount on Scarebird GD conversion brackets that reuse the four factory drum-backing-plate bolts. The factory Fit parking-brake cables will not connect, so 1987 Acura Legend cables (BC94043/BC94044) are substituted; the in-floor cable slots must be ground roughly 1/8 inch wider with a dremel, and the cable-holding bracket must be rebent to accept the larger cable ends. Some rotors will not seat flush on the Fit hub and require the center register lip machined on a lathe. The brake hoses must be replaced with conversion lines (approximately 36 in, with a female 10x1mm end and a 30-45 degree banjo 10x1mm end).

Important Caveats

  • For spirited or track driving, the stock proportioning valve may allow the rear discs to lock because discs require less line pressure than the original drums; a proportioning valve or a careful balance check is advised. Street users report acceptable balance.
  • Reman calipers (e.g. Centric) tend to develop surface rust quickly; wire-brush and paint before installing.
  • Aggressive pad compounds wore rapidly on the lightly loaded rear axle in street use; a daily-driver compound such as Centric Premium Ceramic is more suitable.
  • EP3 Civic Si rear discs are an alternative of the same size (matching the DC2R 10.2 in rotor) but require matching parking-brake cable and caliper styles.
