>>1713459You can try replacing your 1.5mm brake cables with heavy duty 2mm cables. I put NOS 2mm cables on all my retro builds. It’s noticeably more responsive.
2mm is what was used back in the early days of MTBing, and was probably switched to 1.5mm in order to save a few pennies.
If you cant find NOS, you can get cables and housing from motorcycle parts stores
