‘16 Forester Prem 79k mi. Subaru says brakes are good. My brakes shudder/vibrate only when slowing from 60mph+ and I think only going downhill, vibration stops below about 40mph. Vibration is moderate, gets worse the harder I brake, and does appreciably extend stopping distance. I can slow from 80mph fairly rapidly with no detectable vibration as long as it’s not downhill. The exit off the freeway to my house is downhill, so I experience it every time from work unless if I brake much more gradually. I followed instructions to temporarily disable my ABS, and there was no more vibration anywhere from any speed even with heavy braking, so thinking it’s not a rotor/pad issue. Maybe an ABS issue, or maybe a suspension issue the ABS reacts poorly to. Any input helpful, thanks!
