Removing the Final Two Bolts from the Caliper

MARK BLOCKER: In this segment, we're going to cover removing the calipers part two. The next thing we'll have to do to remove the caliper is the two bolts that hold it onto the mounting bracket. Those two bolts have a 12mm head on them and they can be gotten with a ratchet and socket. So, I'm going to break this one free first. The lower one down here is got the brake hose for the hydraulic portion of the caliper. And you have to kinda slide the socket up underneath. It can be a tight fit. Once you get the socket on there, then you can get your ratchet attach to the socket itself and go ahead and break it free. Now, you got both broken free. You just go ahead and remove the bolts entirely. I'll just ratchet it all the way out. Again, it's one of those situations where we got a little bit more--once you get the bolt broken free, it's easy to twist with your fingers. It'll go a little faster that way. Also, a little tip I'll show you. When you're breaking bolts free, you want to always try and pull towards you because it gives you a safer operating--pulling towards you, there's less chance of something getting in between you and what you're trying to break free. But if you have to push the ratchet forward for any reason to breaking that free, if you get your hand wrapped around it and you're pushing forward, the bolts breaks or slips off and your hand can get jam into something damaging your knuckles. This is something I've done many times before I've learned this lesson. If you get in that situation where you have no choice but to push on it to break it free, open your hand up, do it with the palm of your hand. That way, if anything slips or break free, you've got the full contact surface of an open hand. Less damage done, no injuries, and you don't get banged up knuckles. So, just a little tip if you get a tight bolt in a bad situation to break free so you prevent injuring yourself. So, I'll just go ahead and walk out of this other bolt with my fingers real quick. And hopefully, that tip might save you some banged up knuckles because if you ever had, I mean, they're extremely sore. It makes them hard to work with your hands for several days. And you want to make sure you set those two bolts aside and keep them together. Now, we got the bolts out, you broke it free. Before we can remove this caliper, we have to release the parking brakes. The parking brakes hold in the rotor in place now. We had it set to remove to lug nuts on the rear tires. We're not going to be able to get this caliper off until we do that. The piston is ceased down tight by the braking mechanism so we need to remove the emergency brake prior pulling the caliper off. Now, once you got the emergency brake released and the caliper bolts are out, just go back and forth a little bit to kind of break it free and just gently a little bit back and forth. It's just straight up and off the caliper mounting bolt. Now, it's going to fit real tight in there before like on a front brake system, you have quite a bit of leeway to how far you could removed the caliper. In this situation, we've got a parking brake cable attached to the caliper and the brake hose attached to the caliper is going to kind of limit to how far we can remove this caliper out of our way. So we just kind of release it and push it backwards and set it off to the side a little bit. And that will conclude what's necessary for removing the rear caliper. You'll need to do the same procedure on the other side of the vehicle after you've got the other side completed. Please watch our next segment on removing the brake pads and caliper mounting brackets.
