Feedback in brake pedal (not warped rotors or ABS)
I have a 2017 Outback with 37,000 miles. Every so often when I brake moderately hard I get an odd feedback through the brake pedal. It's similar to the feeling when the ABS is activating, but it's more pronounced and much much slower (Let's say for the sake of argument that ABS cycles 15x per second, this mystery feedback is maybe 2x per second). It's difficult to describe, almost like a pop in the pedal like it's ratcheting down as I apply the brakes. But again, this is only happening on a moderately hard braking event, for example stopping at a yellow light when going a bit too fast for the light timing. It might pop maybe 2-4 times as I stop. I can't figure out what causes it to happen, but it does always seem to be within the first few minutes of a trip.
I first noticed it at maybe 10k miles, but it was so infrequent that I never remembered to follow up on it. I took the car in a little while back for some other minor things, and the dealer blamed it on rotor runout. I explained that this was a completely separate issue from runout pulsing or warped rotors, but the service writer claimed that the rotors were so out of spec that it was tripping the ABS. I felt this so be BS, but I didn't pursue it, and the issue didn't repeat itself for a few thousand miles. However, it happened again today and it's becoming a concern since, you know, it's brakes. I've never felt that braking was impaired, but I have a concern that this might change at some point. This is the car that my family rides in.
If you're still with me thanks. I'll most likely bring it back to the dealer (where they'll tell me they can't reproduce the issue) but I'd like to hear if anyone else has experienced this before, or any other ideas on what to check.
