Brake caliper bracket..

[zeroescape]

Lol, as an engineer for the biggest oilfield part supplier in the world, I can tell you that we do in fact use factors of safety well below 2. The lowest I've used is a 1.1, and that's a particular standard that's well established. Aerospace commonly used SFs below 1.5 in their applications to save weight.

Are those SFs for parts that see frequent loading and unloading though?

or parts that just see constant force through its life.

Frequent loading and unloading, temperature changes, wind, rain, pressure, vacuum...

All at 1x safety factor.

Lol extremely frequent loading and unloading. They're components that are attached in the drill string, subject to all the torsional loading and unloading that the entire drill string is, plus pressure differentials and all other means of loading.

Just for giggles I looked up shipping weight on some 2013 Mustang front calipers.

Base calipers are 8 lbs each, plus 3 lbs each for the brackets. OEM pads 2.5lbs per side.

Four piston Brembos are 8 lbs each with built in brackets. OEM pads 2.5lbs per side.

Six piston Brembos are 9 lbs each with built in brackets. OEM pads 3.5 lbs per side.

Again, those weights are all based off what Ford shows as the packaged weights so those aren't the actual weight of the parts but it does give a fairly good idea what the difference in weight is for the various caliper setups. Rotor weight is something else entirely of course.

Steve, I don't think those numbers are accurate for the Shelby stuff. In the post below, I weighed my '13 Shelby brakes on my scientific bathroom scale. The six piston Brembos are quite a bit heavier than that.

Nonetheless for the intent of this thread, there are far easier ways to cut weight than caliper brackets.

Well like I said I'm just looking at what Ford has listed on their site. Nice to see actual numbers.

Just get some fixed 4-6 piston replacement/upgraded calipers with alum brackets and be done. You wont see aluminum floating caliper cages only fixed brackets.

I would rather see a alum spindle IMO

Griggs has an aluminum spindle for their SLA

...and money no object. I'll bet what is in that picture is worth as much or more than some of our entire cars.

Here's the thing many many cars have lighter brackets... So it's not a case of should... But if have been done... Diff year... Diff make model... Etc
