Why Grant Park's hills matter
Hills build heat — heat warps rotors.
The streets roll and dip around the park, dropping toward Memorial Drive and Boulevard and climbing back up near Cherokee Avenue. Easing down a grade means riding the brakes, and riding the brakes builds heat — and heat is what warps rotors and glazes pads over time. That's why Grant Park drivers feel that telltale vibration or pulse through the steering wheel a bit sooner than the flatland average.
Here's the good part: warpage doesn't always mean new rotors. We measure yours with a micrometer against the minimum stamped on the rotor — if there's enough material, some can be resurfaced. Plenty of jobs reach us as second opinions, and often it's just pads. See how we decide on the full brake-repair page.
