The brake caliper is a part of the disc brake system. Some cars have the brake caliper in the front while some have it in the rear. When you are driving your Subaru and press the brake pedal, it is actually the brake fluid flows to the caliper, and the fluid generates a pressure on the piston inside the caliper, further leading to the brake pads against the rotor to stop your Subaru. However, after a long time of getting heat, the brake caliper can be rusty and start to leak brake fluid. So if you find any brake fluid leaked, there is something wrong with your brake caliper. Since we understand you cherish you Subaru car as well as your hard-earned money, you want to help you save a lot of money. Instead of fixing it in the store, you can get a brand new genuine brake caliper here with a surprisingly low price and fix by yourself.
