When one side of your Jeep's brakes runs noticeably hotter than the other while you are driving — not just after heavy braking — the cause is almost always a brake caliper that is not releasing properly. Instead of clamping only when you press the pedal, a stuck caliper maintains constant pressure against the rotor. That continuous friction generates sustained heat, which is why one wheel gets significantly hotter than the other during normal driving, not just during stops.
What is happening mechanically, and why does it happen
Calipers work by using a hydraulic piston to push the brake pad against the rotor when you press the pedal, and to retract it when you let off. That retraction depends on flexible rubber seals inside the caliper staying pliable and functional. In Michigan's climate, the freeze-thaw cycles and road salt that are common around Ann Arbor accelerate corrosion on caliper slides and guide pins. When those slide pins corrode or seize, the caliper cannot fully retract, causing the brake pad to drag.
You might notice your Jeep pulling toward the hotter side during braking, or that it requires slightly more effort to maintain speed (because one brake is effectively working against the drivetrain). The rim of the affected wheel may be hot enough to feel radiant heat from a short distance away, while the opposite side remains relatively cool.
Brake heat on only one side is hard on the rotors and pads. It can also stress the wheel bearing on the hot corner and create an uneven brake wear pattern.
Hoover Street Auto Repair in Ann Arbor can inspect both front and rear calipers, clean and lubricate the slide pins, and restore even braking across all four wheels.
