On certain vehicles, the flexible brake lines which connect the master cylinder to the ABS modulator may have been routed in such a manner to cause a chafing condition between the flexible lines. Chafing can cause a brake fluid leak in either one, or both of the lines. Correction: Master cylinder to ABS modulator lines will be replaced with new lines that eliminate the chafing condition.
On certain vehicles, the nuts used to attach the master cylinder to the hydro-boost unit are of the metric type rather than the required English type. Although the English threaded bolts will accept the metric nuts, torque retention and clamping load of the nut-to-bolt joint is compromised. A loose master cylinder condition can occur, causing longer than normal brake pedal travel during brake pedal applications. Correction: Mounting bolts and nuts will be replaced with the correct compatible attachment hardware.
