I'm not sure if there is anything that can go that wrong when changing pads... I just lubricate the pins and the pistons, brush the calipers add some anti-squeal paste at the edges of the pads and assemble the calipers.... or you're just getting better at doing brake jobs.There shouldn't be any wear difference between braided and non-.
In the past, I once had significantly uneven wear of the pads on the front axle between wheels and within the same caliper. A car mechanic had suggested that either the caliper had a problem or the hose had developed a stricture internally, something that can't neither be seen or felt by hand. Externally the hoses had no signs of wear. I changed both the front OE brake hoses with a pair of TRW hoses and the problem of the uneven wear resolved immediately.
But there was always a little difference, not significant. A little, but visible. With the Goodridge hoses as far as I remember, it was the first time I observed 100% even wear in all 4 front pads.
Also one of the rear calipers wears the outer pad, the one on the opposite side of the piston, more. That's something that started since the car was new and has become worse the last year. That's the first time I will change rear pads while I have installed the Goodridge brake lines. I'll see if they are going to make any difference in the rear.
