- This video covers how to fix and service a seized rear brake drum. While I'm working on a 2003 Ford Escort ZX2, this video also applies to any drum brake system that is adjusted via the parking / emergency brake regardless of manufacturer. This includes other Ford Escort Modem years. This video is an in-depth, step by step guide on how to do this job without the need for power or air tools.
The brake drum in this video was completely seized. Pressing on the brake pedal would not cause the brake shoes to move. This was due to multiple issues that I discuss & address in this video.

I’d consult with the owner before reassembling the brakes. Changing the wheel cylinders are easy but much easier when you have it already disassembled.
A conversation that should take place prior to checking them and doing that much cleaning.
Also a good idea to change the brake fluid at this point. Yes change the brake fluid about every 3 years. The corrosion inhibitors in the brake fluid break down over time and actually become acidic to your inner brake lines and eat away your brake lines.
Never push a brake caliper cup/piston back inside the caliper with fluid inside. This pushes debris back up inside your ABS system and cause havoc with your sensors giving you a light. Sometimes shorting out on a solenoid. Some fragments in the break fluid become electrically charged and weld themselves on contact to solenoids. Giving you problems.
Just flush the system with new brake fluid every time. And yes physically open the bleeder valves and drain the fluid. Manually flush each wheel to ensure clean fresh fluid is in each wheel.
I have fixed far too many mistakes made by others.
Re pushing a piston back into the bore causing damage: That is a really old and disproven myth. If your statement was correct the simple act of using the brakes would cause damage, which is not the case. Fluid flows in & out of the caliper & ABS system when you press/release the brake pedal. Thats how hydraulic brakes work. Due to fluid dynamics, the brake fluid circulates through out the entire system over time. So the fluid in the caliper will flow up through the ABS module and into the reservoir and all the way back back down to the caliper over and over again through the normal use of the brakes.
Factory service manuals also state to compress the pistons back into their bores when replacing pads. There is no other way to get the piston back into the bore but to compress them. I hope you aren't recommending draining the caliper completely before compressing the piston. That would be a little overkill.
Anti sieze on wheel fasteners is not a good idea. Clean and torque properly. Everything else was just fine.
You've probably never been stuck on the side of the road trying to get the lug nuts off in an area that uses a lot of salt on the roads in the winter. I've been putting a little bit of grease on the studs for over 20 years, and my dad did for years before that, on our personal vehicles without any issues. Never had a lug nut come loose. Either way, if you don't want to apply grease you don't have to. Its entirely up to you.
why bother putting the drum screws on at all. seems pointless. especially as if you say you're stuck on the side of the road
You mean the screws that screw the drum onto the wheel hub? The "stuck on the side of the road" comment is about putting grease on the wheel lugs, not the drum screw. You're not going to be messing with the brakes when changing a tire on the side of the road.
As for the drum screw, you don't have to put them back on if you really don't want to, but they do make it easier to adjust the shoes. They prevent the drum from inadvertently sliding out as you are doing the adjustment. If the drum slides out a little the shoes may not be in full contact with the drum giving you an incorrect adjustment. Even worse if the drum is slightly worn, the shoe could be in contact with the wear lip on the outer edge of the drum giving an even worse adjustment. If you don't have the screws, you could take a lug nut and screw it all the way down to hold the drum in place. Up to you.
do you know where I could find a parking brake lever by any chance?
Not a new one. I'd suggest hitting up your local Pick-A-Part/Pick-N-Pull/Junk Yard. Good luck.
Hello, I'm hoping your can assist me. I have a zx2, followed all the directions, including adjusting the parking brake mechanism to allow the drum circumference to get smaller. But alas I can't get the drum back on over the new shoes. After 50 tries, I ended up putting the old shoes (reversed positions to allow different wear) on the drum; they went on perfect. But the new shoes just seem too thick, even with attempting to force them on by pounded. Any suggestions?
SuperJamster1, you likely need to compress the wheel cylinder pistons back into their bores to reduce the circumference of the shoes more. Take the cap off the master cylinder reservoir. Then compress the shoes inward which will push the pistons inward. That should give you the clearance you need. Make sure to keep an eye on the master cylinder to make sure the fluid doesn’t over flow while you’re compressing the shoes. Good luck...
Thanks, I'm going to take a little break from it. It's gotten cold outside again. But I'll give your great suggestion a try. I really appreciate your assistance. Such a simple repair getting the best of me is very frustrating.
SuperJamster1, no problem. Good luck...
My Escort's parking brake assembly inside the drum is covered in black and is seized. I've removed it from the car. How do I unseize it without moving the pressed on nut - soak it in brake cleaner, paint thinner, acetone, or what?
I would hose it down with brake cleaner to get any oil & dirt off of it first. Then wipe it down really well to see why it is seized. Then you can soak it in penetrating lube and keep soaking & working it until it (hopefully) comes loose. I wouldn't use paint thinner or acetone because they could damage the rubber seals. Good luck.
I had to dismantle and sand it. It is held together with a thick steel push nut/bolt retainer. Where can I find a replacement push nut?
Glad to hear you got it figured out. I would check local junk/salvage yards first and take one from a junked Escort. If that doesn't work check your local dealer. Good luck.
AutoZone has the grease
Yes, most auto parts stores do. It is a common lubricant.
Keeping place of everything is good but at least I can use ur video to know we're it was and how it gonna be placed back
Yes, you can use videos like mine as a reference/fallback if things get mixed up. But it is always good to keep track of your parts, just as a general rule. Thanks for watching & commenting. I appreciate it.
Great video! This will come in handy when I check out the corolla's drums. Apparently, I can't like this video from my phone, but I will once I get on the computer!
Thanks a lot. Hope it helps.
Pet Rock's Garage I hadn't thought about putting anti seize on the drum where it touches the hub. Obviously, that's where it rusts, but, yeah, hadn't thought of it. :) Thanks again!
Anti-seize is a wonderful thing. 1001 uses. :-)
Wouldn't it be a good idea to clean and grease the bottoms of the spring clips, and their mating surfaces on the shoes? The pins are narrow and the matching holes in the shoes are large to allow for shoe movement under the spring clips.
Cleaning them is a good idea, but greasing them won't help because the shoes do not slide against the spring clips. You only need to grease areas where metal slides against metal. Good luck...
This is great, thanks man
thanks. I appreciate it.
