Brake calipers are a critical component of the disc braking system, working in conjunction with brake pads and rotors to slow and stop the vehicle using hydraulic pressure. Signs of a failing caliper include pulling to one side, increased stopping distances, brake fluid leaks, or a seized piston causing constant drag. Replacing both rear calipers as a matched set ensures balanced, even braking performance. Professional installation is recommended.
