Most car crafters realize they should regularly change the engine oil, coolant and transmission fluid, but completely overlook the brake fluid. Just like other automotive fluids, brake fluid becomes contaminated with dirt and water condensation, which will affect its performance. Tech+Plus (Dept. CC, 4600 Whitmer, Industrial Estates, Ste. 2, Niagara Falls, NY 14305, 905/822-3330) offers an easy-to-use brake-fluid checker that analyzes the condition and boiling point of your brake fluid. Simply hook up the positive and negative wire clips to the battery, then insert the tool into the brake fluid within the master cylinder. Depress the "ON" button and, within moments, the Tech+Plus tester will deliver the needed info.
