Deliver pressurized brake fluid from the hard line to the front-left caliper with the Dorman - First Stop Brake Hydraulic Hose H621945. This position-specific hose drops in as a direct-fit replacement for the 2013-2018 Cadillac ATS [All] and the 2014-2015 Cadillac CTS [All], built to precise measurements so it matches the original front-left hose's fit and function on these applications for an exact fit and easy installation.

  • EPDM rubber construction: flexible hose with specially coated, corrosion-resistant fittings for durable, long-lasting service as part of a complete brake repair.
  • Position-specific fitment: cataloged for the front-left location, with an overall length of 18.06 in.
  • Fittings: Banjo fitting on end 1 (10 mm thread) and a female fitting on end 2 (M10 x 1.0), both in treated steel.
  • DOT approved: materials tested to exacting government-regulated safety and durability standards; includes gaskets.

Bracket and mounting hardware are not included — transfer or replace fasteners and brackets as directed by the service procedure. If a cracked, bulging, or leaking front-left flex hose is causing a soft pedal or fluid loss, this replaces it. Country of origin: China.
