Checking Brake Lines and Cables

WARNING: This page is about a different car, the 2007 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: If leakage occurs around hose and tube connections, retighten or, if necessary, replace damaged parts.

Check the brake lines (tubes and hoses) and parking brake cables for improper attachment, leaks, chafing, abrasions, deterioration, and damage. Repair or replace parts as necessary.
Apply a stepping force of 784 N (80 kg-f, 176 lb-f) to the brake pedal with the engine running and keep it for about 5 seconds, then check each part for leaks.
