Right front vs left front calipers

That looks like a way easier setup than trying to hold the flex bracket and the caliper all together as one haha!
I agree with you, there.
I think The Kelsey Hayes, Mustang calipers with the hose bolting directly into the caliper is a much better arrangement.
Don't know the reason why Mopar had to use a hard line, a hose bracket, then the rubber hose bolting down onto the hard line?
