Bleeding Brakes:
Kraus has taken the necessary steps to allow for an easier installation compared to any caliper on the market. Each caliper is pre-bled in-house, though a confirmation bleed is still necessary. Featuring re-engineered styling, we’ve incorporated an outboard bleed nipple and banjo take-off, making bleeding and installation easier while allowing fluid to fully circulate the caliper.
FITMENT
