Restore a firm brake pedal and safe hydraulic pressure to the front-left corner with the Dorman First Stop Brake Hydraulic Hose H620427. Precision-built to the correct length and fittings for the front-left position, it installs as a position-specific replacement on the 2003-2007 Cadillac CTS (All engines), carrying pressurized fluid from the hard line to the caliper while flexing with steering and suspension travel.

  • EPDM rubber hose: a flexible hose made from EPDM rubber, measuring 18.75 in overall in black.
  • Corrosion-resistant fittings: a treated-steel banjo fitting on one end and a treated-steel female fitting on the other, specially coated to resist corrosion; End 1 uses a 10 mm thread and End 2 a 7/16 in-24 inside diameter.
  • DOT approved: materials tested to government-regulated safety and durability standards.
  • Bracket & gaskets included: ships with a stamped-steel bracket, sealing gaskets, and a protective outer jacket; mounting hardware is not included.

Signs a brake hose may need replacing include bulging, cracking, or fluid seepage at the fittings, and a soft or spongy pedal. If a failed front-left hose is the cause, this replaces it. Country of origin: China.
