GENERAL MOTORS issued a recall on the S10 and SONOMA models

Certain vehicles do not comply with the requirements of CMVSS. 105 - Hydraulic Brake Systems. The right hand ABS module feed pipe and/or brake crossover pipe tube nuts may have been tightened without seating the pipe flared ends enough to withstand normal assembly and vehicle inputs without partially unseating. If the seating seal is broken, brake fluid leakage could occur. Correction: Dealers will inspect the union for signs of brake fluid and, if necessary, install a new union.
