Fuel Economy Tip - Have Your Brake System Checked
June 27th, 2007 | by Brian Carr |If you notice a gradual or even sudden decrease in your car’s gas mileage (assuming that nothing drastic has changed in your driving habits) there are several things that could be going on with your car that might be causing the drop in fuel economy.
Maybe you’re driving around with a dirty or clogged air filter, fouled spark plugs or under inflated tires. There’s also the possibility that the culprit could be one of the last things you might suspect - your car’s brakes.
It shouldn’t come as much of a surprise, but if your brake pads are constantly engaged it’s going to take much more energy for your car to get up to and maintain traveling speed. This extra energy will need to come from burning/wasting extra fuel.
There are several things that could cause your brakes to constantly drag:
- One or more of your brakes’ calipers may not be fully retracting after you have disengaged your brakes.
- The emergency brake doesn’t fully release due to a malfunctioning cable.
- One or more of your brakes’ retaining springs or clips may be defective and causing the brake pad to not release from the rotor.
Obviously these are just a couple of the potential problems. However, because your car’s braking system is absolutely critical to your safety and well being, please take your car to a professional to have the problem properly diagnosed and taken care of.
While you have your car in the shop, it might not be a bad idea to have the mechanic look over the rest of your car to see if there’s anything else that they might be able to repair that might help improve your car’s fuel economy.
Even though it might be a pain to fork over the money now, if you keep your car properly maintained over time, you should be able to recoup much of the cost by saving money at the pump.

I just replaced my front brake components (pads, rotors, calipers) due to a stuck caliper dragging. I will be sure to keep track of any improvements in my fuel economy with new brakes.

You are quite correct!
Many people do not realise that by keeping your car in good working order can actually reduce your running costs.
