I've driven my 2017 for 22,500 miles in mixed conditions and have not found this to be an issue at all. I find the brake travel is progressive, smooth (and definitely not spongy). Brake wear has been good too. Hardly noticeable wear when examined during the last tire rotation at 20,000 miles.
This is an easy vehicle to drive smoothly - including smooth starts and smooth, consistent braking. Also, towing a 4,500 lb boat (which has surge drum brakes only) the Ridgeline's brakes handle this load with no issues or fade.
I'm a ROC (Ridgeline Owners Club) Senior forum member and you need to remember we have a lot of grumpy old guys that own Ridgelines...Many with a lot of time to complain about stuff...Some of which is a non-issue...
It is possible that some do have a braking issue most likely due to air in the lines or similar but both the Gen 1 and Gen 2 brakes have been a non-issue and my 2010 G1 Ridgeline went 40K miles on the rear pads and over 60K miles on the front.
