Any time you have brake pulsating the first thing to look for in my opinion would be for warped brake rotors for the front(rear if it has rear disc) Or warped out of round drums. 6. Gas engines have more engine braking (compression braking) at higher RPM. Hammer the brakes and repeat. It’s now 6 months later and I’m having the same problem. And while pulsating while braking is usually an easy fix, any issue with a vehicle’s braking system is a safety concern. In other words pressure is reduced to the rear brakes during weight shift. Brake pedal gets funky, hard to push, vibrates, like ABS is triggering. 1. On flat roads it was fine.
