Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Use a pry bar or a large flat bladed screwdriver to remove the hub cap. Just going to slide it under the edge and put that aside. Using a breaker bar and a 21 millimeter socket, and loosen the lug nuts when the car is still on the ground. Raise and support the vehicle. Now you can finish removing the wheel. These lug nuts are pretty loose, so I'm just going to use a socket, take them off. I'm removing the last lug nut, and I'm just going to hold onto the wheel so it doesn't fall off. Take it right off.
Start by removing the two caliper pin bolts: one on the bottom; one on the top. These are 14 millimeter. That one actually broke free without having to use the mallet. If it's tight, you can take a mallet and just tap it and break it free. Just kind of squeeze the caliper a little bit by pulling it out. It should slide right off the pads. Take a bungee cord and just hang it up and out of the way. I'm going to use a small pry bar or you can use a flat bladed screwdriver. You need to pop them away from the brake rotor out of the caliper bracket. Remove the caliper bracket bolts. There's two at the back: one on the top; one on the bottom. They are 14 millimeter. They'll be in there pretty tight. Use a box wrench and a mallet and break them free. When you get the bottom one loose, then work on the top one. As they're broken free, you can switch to a ratcheting wrench. They're pretty loose, so then I remove the bottom one with my fingers, set aside to reuse it.
Now you get the top one out. Pull the bracket out and the bolt out. This car is missing a rubber plug that goes in the rotor here. The rubber plug is so that you can access the parking brake mechanism to release it. Somebody just put some duct tape over it. I'm going to peel it off. Inside here is the mechanism. I'm going to try to pull it off first, though, because sometimes it's loose enough you don't need to release it. Parking brake's not on, it is spinning free. I can spray some rust penetrant around the hub, a little bit in here. Take our dead blow mallet, I'm going to hit around the edge here to try to break it free. Sometimes you'll get lucky, these might come off, but they usually get stuck on the parking brake shoes. You need to release the adjustment. It's very hard to see right now, but through this opening that normally has a rubber plug on it, it had some duct tape on it, we removed it, take a flat bladed screwdriver, we're going to spin it, trying to grab the little tabs on there and spin it up to the little wheel. Make sure I'm going the right way.
You can check. See, I went the wrong way. It locked it, so it's going to actually be spun down. You basically just have to spin that wheel down and keep retracting the parking brake shoes in so that the rotor will come free. When you adjust it, you're going through the rotor and into this hole. Then you're pushing down on it, and that spins the parking brake shoes in to release them.
To cut down on some of the brake dust that's in here, I'm going to take some brake parts cleaner before I remove all the hardware in the shoes and clean it out. To remember how this goes back together, I'm going to use my phone, take a couple pictures of it, underneath. I'm going to take some needle nose pliers and remove these two springs up top that are holding the brake shoes on. That one. You'll pull this adjuster piece out. I'm going to put the spring back on it just the way I found it, so I don't forget how that went together. Now the shoes are just on these little retaining springs and the hardware that's underneath them. These are usually a pretty soft springs. They're kind of keyed, so you can turn them by just kind of compressing them.
Sometimes you have to reach in the back and actually hold, they call it a nail that they're held onto, you can actually hold the back of it so it doesn't get pushed through. Some pliers in here, push it down and attempt to turn it. Whoops. Put those springs aside. The shoe should come off this. Grab this little washer, too. Slide this down. This is the auto-adjuster. Put that aside so I don't lose it. I'm going to repeat the same on this side, remove that little spring and retainer, so you can actually take, this is what they call a nail because it looks like a nail, you can actually take this out and put that aside. Same exact thing. There is a tool for this, but it's actually not a lot of clearance in here to get the special tool in here to push these in, so pliers work pretty well. Lower this all down.
Take the nail out. That's interesting, this one has a little special taper to it, so that's the other side. Now, this is your parking brake cable. Let's try pushing this this way. Got one part of the needle nose on the end of the cable and one on this brake shoe arm. Pop it this way, it almost worked. These brake shoes are in good shape, we're not going to replace them. If you did have to replace them, you would reuse this arm, this is what gets pulled when you push down the parking brake pedal, and it spreads the shoes out inside to lock the brake rotor.
To replace it, you'd spread apart this clip and pop it off this pin. Then you'd swap this over to the new brake shoe, put this clip back on, and squeeze it back together. That's really the only major thing you have to do. Other than that, you just replace the same hardware that we already have, and put it back together in the same way you took it apart. This is what we're going to do now. I need to get the brake cable back into this holder here. I'm going to try some locking pliers. I don't want to crush the spring, so I'm just going to set them so they don't pop off. I can use these now. I need to attach this spring that goes on the back side to this retaining spring. Going to get it into place, so this rounded part of the shoe is going to fit on this pivot point here. This nail or retainer for the brake shoes has this bend in it so it's offset. It comes through here, and then it's offset so that it can go around this and sit in here.
I'm going to install it from the back. Spin it in place. Slide this assembly up, trying to get it to hold the part from the back. Nail, just slide this little cup in there. Take our retaining springs, put that over the little retaining part. Try to line up the slot on the top of the pin to that wide opening, and then you turn it to lock it. You may be able to use the opening in the hub here to help go through and set up the retaining spring. You just want to make sure that this is pushed in and turned so that it's locked in place. On the inside of the opposite brake shoe is the same type of little hook part. I'm going to hook the spring onto the inside of that one, and then hook it onto the inside of this one. Put the shoe into place, and attach the retaining spring and nail. Take these pliers, get that one hooked in place.
This is the adjuster that, when it turns out, pushes the shoes out, so you adjust the tension on the shoes. They also automatically adjust as they wear. This spins nice and freely so we don't need to clean it up, but we need to install it in place before I get too far. It sits right in here, and it's going to sit, I'm going to pull this shoe up, and it's going to sit just like that. To put the other side, nail goes in through the back. You can see it better on this side. Make sure that this little retaining tab goes into this little hole over here. Put that into place. Reinstall the spring and the seat, just like the other side. This plate here with the spring, put the spring back on it. It slides into the parking brake arm and shoe. Separate this one a little bit apart, just get it lined up because it fits together like that.
These springs have a hook. The hook is going to go around this portion here. Then this end here is going to slide into the opening to the bottom of the brake shoe right here. With that in place, grab them with pliers, pull them down and over the pin. We'll just make sure that that shoe fits in that slot and presses that spring, because these two shoes should be resting on this pivot point here. Just making sure everything's connected so all of our parking brake hardware is now in the correct place.
Install the rotor backwards. Take brake parts cleaner and clean off the oil that comes on these so they don't rust while they're shipped. Flip it over. Make sure you install it in a way that this hole lines up with one of the openings here so you can adjust the parking brake. Instead of taking our caliper off of our bungee cord, I'm going to take one of the old brake pads. Take a C-clamp, and now what I'm going to do is gently compress the caliper, push the piston into the body, and that way when we put our new pads in, it'll slide right together. Just going to rest the caliper like that. Take the brake parts cleaner, and clean it off.
Install our caliper bracket. Get the top one caught first—it makes it a little bit easier. Then install the bottom one. It’s a little easier because it just hangs on the top one. Reach in behind here, get that bracket lined up. Use the 14 millimeter ratcheting wrench to snug these up. Install our new pads, just take some brake parts cleaner, make sure they're nice and clean. Brake caliper grease on the ears of them. Inside and outside pad is the same, I'm going to start with the inside pad. Place it in the bottom clip, push it up into the top clip, snaps into place. Do the same for the outside one. We're just kind of following the curb of the pad, too, they're contoured, so the wider part is going to match up with the wider outside part of the rotor, and the inside part. Just push them down into the clips. Squeeze them together.
Place the caliper back in place, and reinstall the bolts. Tighten these up. They'll get tight and I will stop. I torqued the caliper bolts, 46 foot-pounds. You need to adjust the drag on the parking brake. You can turn this so you can see the adjuster. Then you can put your screwdriver in and just catch the gears in the wheel just right, so now that's how you'd adjust it so that it's actually really tight, it's holding the brake rotor. Now you know where the limit is. You want to back it off a little bit by turning it back down. Eventually, if you touch the parking brake pedal it would self-adjust out, but this way it just gets it closer right away.
Now I'm going to reach in and turn it down a little bit. What it's dragging on right now is just the brake pads, but that should spin freely enough. Of course, when you hit the parking brake pedal, it should come out and lock the rear wheels. Important to note, these lug nuts have a taper. Taper meets the wheel, matches the inside of the wheel. Don't install them the flat side like this, that is incorrect. Install them with the taper to the wheel. It helps locate the wheel on the lug nut stud.
I'm just using the socket and ratchet to bring these down snug before I put the car on the ground, and torque the lug nuts to 76 foot-pounds. I'm going in a cross pattern. We'll reinstall the hub cap. Going to line up the opening for the valve stem with the valve stem on the wheel. Just push it in place.
Before we start the car, just going to gently press the brake pedal down, not all the way to the floor, maybe about a quarter of the way, and just pump it. This will bring the brake caliper piston out to meet the pads because we compressed it, and you'll start to feel it get more solid as it pumps up.
