The Legend GS front calipers are dual-piston units and come as loaded assemblies, so they bolt to the 1G CL front knuckle without adapters. Pair them with the larger 11-3/32" (11.5") front rotors from a 1996 Prelude VTEC (part number 39796374R) rather than the smaller 10" rotor some applications used. Fresh front brake lines are recommended while the hydraulics are open. The Legend proportioning valve is not needed; the CL's existing brake balance was reported to work fine after the swap. This fitment applies to the 4-lug 2.3CL; other 1G CL trims may require different rotors.

Important Caveats

  • The calipers are stamped R and L but must be fitted on the opposite corners so each bleeder screw sits at the top; installed as marked, the system cannot be bled.
  • The two pistons in each caliper are different sizes, so left/right placement also sets piston orientation, reinforcing the need to fit them on the correct corner.
  • Whether the Legend proportioning valve should also be swapped was debated; the installer ran without it successfully, but one commenter suspected the larger front calipers could shift front/rear brake bias.
  • All 1997-1999 CLs are 4-lug; confirm your rotor and hub pattern before ordering.
  • Brakes are safety-critical; verify the finished system before road use.
