Scott,I read long ago that someone had fitted their disk brake pads with springs to keep the pads off the disks and therefore reduce drag. Any ideas out there on where I can get these? I think they would be hard for me to fabricate.
For older vehicles there are a lot of nice caliper upgrades, look good, lighter, better brakeing performance.
Stainless would be a horrible metal to make disks out of. It sheds heat poorly and will warp in no time flat. The only 2 really viable options I know of that would be better are ceramic and carbon fiber. Both are much more expensive and I know ceramic has to be hot to work well.I wonder if stainless steel disks have less friction than cheapy iron ones?
I just did this on my '74 bug. The front wheels initially would spin 3/4 of a rev, after adjustment ~20 revs. I didn't see any change in speed or amps pulled, but charge draw changed from my 4.6 kWH usual to 4.56. The brakes had to move much further to engage, but were also much easier to apply as the lever position was now helping instead of resisting.Has anyone done a before and after range or amp test to determine the effect reducing disk brake drag? My 71 Toyota EV has drums but my 88 Bronco II ice has disks up front that feel like they turn pretty hard and my gas mileage is poor.
