You have questions—and Bob Weber, TheCarConnection.com’s on-site mechanic, has answers. This week, Bob’s big riddle concerns anti-lock brakes, or ABS.
“I have read a lot about using ABS—that you should continue to put constant pressure as you brake when the system activates—but I have not read about the usage of traction control systems,” a reader asks. “When it engages, should you release pressure on the gas pedal or let the system work during slippage? What damage could result (to the engine or brakes) if the system is allowed to stay engaged until the tires grip?”
It comes down to integration, Bob says. “Traction control is integrated with the ABS. If one or more wheels are spinning too fast from lack of traction, the brakes are applied until the spinning stops. If the condition persists, the control module will begin depowering the engine until traction is reestablished. In answer to your question, keep your foot in it. Nothing will be damaged.”
