Move brake fluid to the rear left wheel and keep your hydraulic circuit sealed with the Dorman - First Stop Brake Hydraulic Hose H621930. This flexible brake hose is engineered to replicate the fit, function, and performance of the factory hose in the rear left position, dropping in as a direct-fit replacement for the 2012-2014 Cadillac CTS (All engines). A brake hose that is cracked, bulging, leaking, or swollen internally can produce a soft or spongy pedal — if the failed hose is the cause, this replaces it.
