Remove Brake Pads on Mountain Bikes

"So, we'll start off here with the Hayes disc brake. You can remove these pads when they're on the bike, but it's a pretty simple process: just stick a finger in there, pull the pad out, and our pads are out. The Hayes brake pads are actually different for each side. It's hard to tell just looking at them, but you can tell they're profiled a little bit differently. You can see on the back, they've got a little spring, and then a bore on them, which sits over the piston and the brake. Here's a Hayes brake piston. And what we see is that this is the wrong side for this pad because the pad wants to line up with the piston. So I slide this one on, and you can hear and see that it's a positive connection. So they are handed, left- and right-handed. Depending on the type of the replacement disc brake pad that you get for your Hayes brakes, they may or may not come with these little springs. So these little springs are like gold; don't let them go flying across the garage or lose them in the parking lot on the trail because your brake pads aren't going to work without them. And sometimes you buy replacement pads that don't come with them. We're going to move on now to removing Avid disc brake pads. I'm going to leave this one on the wheel here, and it's a similar operation. The inside pad here is actually bent, which makes it easier to grab. I like to grab both at the same time if I can. Tug on them. Going to grab the outside one and that's a little bit rough to get out. So what I'm going to do is I'm going to go to the toolbox and grab some needle-nose pliers, and that's going to make this operation a little bit simpler."
