Can a sticking caliper be cleaned instead of replaced?

Sometimes. Frozen slide pins and a torn boot can be serviced as long as the piston still moves freely. A seized piston, or a caliper that will not retract, needs replacement. We confirm which case you have before you order the part.

Will I need new pads and rotors with a caliper?

If the sticking side overheated the rotor or wore a pad unevenly, then yes, at least on that axle. We measure both sides and add only the parts that are damaged.

How long do brake calipers last?

Often 75,000 to 100,000 miles, and less if the car sat for long periods, the boots tore, or the fluid went unchanged. Moisture in old fluid corrodes the piston bore from the inside.

What a caliper is supposed to do

Pedal pressure sends fluid into the caliper pistons, which squeeze the pads against the rotor. When you release the pedal, the piston should retract and free the wheel. A caliper that sticks keeps applying pressure, or applies it unevenly, so one corner carries more braking load and far more heat than it should.

Why calipers stick

Atlanta rain and road grit are hard on slides and boots. Common causes are rusted slide pins, a torn dust boot letting water in, a collapsed rubber hose that holds pressure, or a parking-brake mechanism that will not release on a rear caliper.

How a Road Wrencher caliper visit works

We inspect both sides of the axle on site so the diagnosis rests on measurements rather than a photo of one hot wheel.

Step 1: We diagnose it. Which corner is dragging, piston versus slide pins, and the condition of the rotor.
Step 2: The exact shopping list. The caliper, plus pads or a rotor if that side was damaged.
Step 3: Flat-rate install and bleed. We bleed the circuit we opened so the pedal stays firm.
