Tried seemingly everything to increase MPG -- wondering if I need a new battery

Like EGR arguments in theory disc brakes will always drag. It may be 1w worth but thats what im saying here. Some of those guys get crazy with it.

Drum brakes actually maintain a gap between the pad and the drum and disk brakes dont.

 

Disc brakes do NOT drag. If they are functioning properly. The normal out of round and
stress from turning pushes the pads back slightly. If they drag, the will get hot, the caliper will
heat up and expand and the pads will THEN will drag and the vehicle will start to pull, and then
the brakes fail. Works the same with drum brakes.

"It may be 1w worth..." I don't understand what that means.

 

How do you push something without touching it? The pads will always drag man I don't know what to tell you. And if you're talking about the force of a spinning wheel pushing the pads out in that physics experiment they do this is the wrong axis from the pads.


Watts are btu/hr so meaning the pads are dragging at such a low rate it is producing such little heat that it is almost immeasurable in perfect conditions of disk brakes. But 1w means they will always be touching the pad.

The pad clips that retract the pads can help but even they typically don't produce a space or gap its just less contact.

 

Sorry you don't understand. I don't know how to explain it any easier....
But it's time to use the ignore feature for you.

 

I honestly hope so. I have no idea how to do that and would love that.

 

At top/right of page, in the pull-down below your avatar, one item is for ignore. Choose that, then down at bottom is a field to type member you want to ignore.

 

Funny, I always read it was the square section O-ring in the caliper that moves the piston back in the caliper when fluid pressure is released. A minute amount.
And those spring thingie clips at most try to keep the pad close to following the piston.
I almost always hear the pad making noise when I spin a brake disc.
You have to get close and have good ears!

Hey, lets have this a 3 Way Block!
If we don't, we may drag this on longer than it has already!

 

Bill you are correct.
I meant these:
Raybestos Disc Brake Pad Drag Reduction Clip
"the disc brake pad drag reduction clip" apparently.

 

Hydraulic bicycle brakes have springs similar to those In cars watt or two is meaningless. Except in some dragsters or such where they use drum brakes to have zero drag
