Got it done yesterday. Was dissatisfied by results of previous brake jobs, one 8 years ago by myself and one recently. Performance after those brake jobs was about like before, not great. So, R4S's , steel braid hoses, rotors turned, new or reman everything else including new master cylinder and aluminum drums (turned), and very competent shop doing the work. All done at once so don't know what made the biggest difference. Not bedded yet, but very noticeable improvement. More noticeable at higher speed / harder braking. Did a bunch of tests for fun. Thanks for advice. Will keep distance from cars ahead and watch the cars behind me, so my better brakes don't get me in trouble with texters and tailgaters.
