Ford reduces front brake drag: efficiency gain = 0.1 MPG (in EPA combined testing)
Just came across this nugget about the redesigned Ford Fusion hybrid, and how efficiency was increased through the application of magic buckshot:

Maybe not news to anyone who has ever spun a jacked up front (or rear disc) wheel by hand. |

Back about 1974, we had a gas crisis and gas went from 30 cents a gallon m/l to 37 cents gal m/l. One of the tips to reduce the drag of the disc brakes was to rock the steering wheel l/r to push the pads apart a tiny bit. I have no idea if it would work or what the effect would be. may look into it.
And don't we have a tip relating to this on this site? I just checked. Not in 100 tips or 65 mods that I could see. Anyway the tip was to add a set of springs/clips (second set of springs/clips?) to push the pads away from the rotor. I did a search. The topic is brake drag reduction clips. Probably should be added to the 65 mods. |

Might as well take the car off a sweet jump. |
Definitely not news to any of us who let a car sit so the rotors get rusty.
It was in fact on this board that I read about people using clips to make the pads retract further on disc brakes. I'm sure there's half a dozen posts about them, it wasn't even a hackjob. Buy the clips, install, and you're done. |

Mazda already did this with the Mazda2 years ago. They let the pads float higher, and redesigned the geometry of the brake pedal assembly so people wouldn't panic over "mushy brakes"
