Brake pads are a wear item that you must have, and even though brake pads don’t cost an arm and a leg, your mechanic’s labor rates might. Unfortunately, maintenance can be pricey and must be done regularly. What Are The Benefits of Knowing How To Release Brake Caliper Pressure? Of course, you should replace a caliper ASAP if it seizes, but you can temporarily free it by releasing pressure and pushing the piston. Similarly, another time you might release brake caliper pressure is if your caliper seizes up. When I pushed the pedal to test my brakes, the piston pushed fully out.īecause of this, I had to release the brake caliper pressure and put my brake pads back in place. However, there are other situations when it comes up.įor example, I once removed a brake caliper to do other work, then forgot that it was not in place. The most common time you’d release brake caliper pressure is when replacing worn brake pads, like the example above. When is it a Good Idea To Release Brake Caliper Pressure? That means, for your new, thick brake pads to fit over the rotor, you have to push the piston back into the caliper by releasing brake caliper pressure. This keeps your brake pads close enough to pinch the rotors, even as they get smaller and smaller from wear.īUT, when you replace the old, worn pads with new, thicker brake pads, the caliper piston is much too close to the rotor. Your brake caliper makes up for this lost material by letting the piston hang farther out of the caliper.

From there, the brake fluid pushes against the brake caliper pistons, forcing them to extend out and push against the backs of your brake pads, which pinch the brake rotors and slow you down. When you press the brake pedal, it forces brake fluid to travel through hoses and tubes, and into the brake caliper. What that means is the entire brake system is sealed from pedal-to-pads, with hydraulic brake fluid inside. How Do Brake Calipers Work?īrake calipers work by hydraulics. Why Do You Need to Release Brake Caliper Pressure?īrake calipers need their pressure released to make enough space for your brake pads to fit in the caliper and slide over the brake rotor.īut why isn’t there enough room by itself? Well, to understand that, we’ll have to know a little about how brake calipers work.
