What Are Brake Shoes: An Ultimate Guide
Published on September 15, 2026
Quick Takeaways
- Brake shoes are the friction components inside a drum brake, doing the job pads do in a disc brake.
- Most brake shoes last around 60,000 km, longer than typical brake pads.
- Replace shoes once the friction lining wears down to about 1.5 to 2 mm.
- A full shoe replacement typically costs $250 to $500 CAD including labour.
- Many economy cars and trucks still use rear drum brakes with shoes today.
A grinding or scraping sound from the back of the car often has drivers asking what are brake shoes, since most people are more familiar with the front brake pads they can see through the wheel. Brake shoes do the same basic job as pads, just inside an enclosed drum instead of clamping an exposed rotor.
MTX Performance carries replacement brake components for a wide range of makes and models, so knowing what you're dealing with is the first step to a straightforward fix.
What Are Brake Shoes
What is a brake shoe, exactly? It's a crescent-shaped metal piece with a friction lining bonded or riveted to one side, mounted inside a brake drum. When you press the brake pedal, a wheel cylinder pushes the shoes outward against the inside of the spinning drum, and the resulting friction slows the wheel down.
What Is a Brake Shoe Made Of
What are brake shoes made of? The core is typically steel or cast metal, shaped into an arc to match the curve of the drum. Bonded or riveted to that base is the friction lining itself, made from a heat-resistant compound similar in composition to brake pad material. Some manufacturers and technicians refer to them by other names too, since what are brake shoes called varies a bit by region, with "drum brake shoes" being the most common alternate term.
Brake Shoes vs Brake Pads
What are brake shoes and pads built for, side by side? Brake pads live inside a disc brake and clamp a flat rotor from both sides using a caliper. Brake shoes live inside a drum brake and press outward against the inside of a spinning drum. Because the drum's rotation actually helps wedge the shoe tighter against it, drum brakes have a natural "self-energizing" effect that disc brakes don't get, which is part of why shoes are still commonly used for parking brakes even on vehicles with disc brakes everywhere else.
Do All Cars Have Brake Shoes
Do all cars have brake shoes? No. Modern vehicles increasingly use disc brakes on all four wheels, especially performance and higher-trim models. But shoes are far from obsolete.
What Cars Have Brake Shoes Today
What cars have brake shoes in 2026 and beyond? Many economy and compact cars still use rear drum brakes with shoes to keep manufacturing costs down, since drum brakes are cheaper to produce than a full disc setup. Trucks, vans, and some SUVs also use them on the rear axle, and a large number of disc-brake vehicles still use a small set of shoes inside the rear rotor hat as a dedicated parking brake mechanism.
Brake Shoes vs Rotors
Brake shoes vs rotors isn't really an apples-to-apples comparison, since a rotor is the disc-brake equivalent of a drum, not of a shoe. The shoe is the friction component; the drum (or rotor, on the disc side) is the surface it presses against. Confusing the two is common, but knowing which part you're replacing matters for ordering the right components.

How to Measure Brake Shoes
Guessing at wear isn't a great strategy, so here's how to actually check.
How Do You Measure Brake Shoes
Measuring brake shoes starts with removing the drum to expose them, or using the inspection hole on the backing plate if your vehicle has one. Use a ruler or a brake lining thickness gauge to measure from the metal base of the shoe to the outer surface of the friction lining. How do you measure brake shoes most accurately is by taking the measurement at the thinnest point, since wear is rarely perfectly even across the shoe.
When to Replace Brake Shoes
Replacing brake shoes comes down to that thickness measurement. Most manufacturers specify a minimum lining thickness of roughly 1.5 to 2 mm before replacement is required, though it's best to replace shoes well before they reach that point rather than cutting it close. If the lining has worn down close to the rivets on riveted shoes, that's also a clear sign it's time.
How Long Do Brake Shoes Last
Typical Lifespan and What Shortens It
On average, brake shoes last around 60,000 km, noticeably longer than typical front brake pads. Driving habits matter a lot here. Riding the brakes, not fully releasing the parking brake, or frequent hard stops can wear shoes down considerably faster than that average.
Why Canadian Winters Are Hard on Drum Brakes
Drum brakes are enclosed, which normally protects them from road grime, but that same enclosure traps moisture and salt brine that gets in during winter driving. Once inside, that moisture can cause the shoes to stick to the backing plate or accelerate rust on the drum's inner surface, leading to uneven wear or a shoe that doesn't fully retract between stops.
How to Replace Brake Shoes on Drum Brakes
Tools and Prep
How to replace brake shoes on drum brakes? It starts with the basics: a jack and jack stands, wheel chocks, a lug wrench, a brake spring tool, a C-clamp, and brake cleaner. Park on a flat surface, engage the parking brake, chock the wheels you're not working on, and always wear safety glasses since drum brake dust shouldn't be inhaled or brushed off dry.
Step-by-Step Replacement Process
How to replace drum brake shoes? In practice, it follows a consistent order. Raise and secure the vehicle, remove the wheel, then remove the drum itself, tapping it gently if it's stuck. With the drum off, use a spring tool or pliers to release the hold-down and return springs, then lift out the old shoes. Clean the backing plate and drum thoroughly with brake cleaner before installing the new shoes in the same orientation, reconnecting the springs, parking brake hardware, and adjuster.
Reinstall the drum, adjust shoe clearance if your vehicle requires a manual adjustment, then reinstall the wheel. If suspension components are already off for access, it's a reasonable time to give MTX Performance's suspension parts a quick look while everything's apart.
Brake Shoe Replacement Cost
Parts and Labour Cost in Canada
A pair of brake shoes typically costs somewhere between $15 and $275 CAD depending on the brand and vehicle, while labour for a full rear drum brake job usually adds another one to two hours of shop time. All together, most drivers can expect a total of $250 to $500 CAD for a complete brake shoe replacement, parts and labour included.
Is It a DIY Job or a Shop Job
Replacing brake shoes is a manageable DIY project for anyone comfortable with basic tools and a bit of patience with springs, though the springs themselves can be more fiddly than a straightforward pad swap. If you're not confident working around drum brake hardware, it's a reasonable job to leave to a shop.
Frequently Asked Questions
Are brake shoes and brake pads the same thing? No. Brake shoes are used in drum brakes and press outward against a drum, while brake pads are used in disc brakes and clamp a rotor from both sides.
How much does it cost to replace brake shoes? Most complete brake shoe replacements cost between $250 and $500 CAD, including both parts and labour.
How often should brake shoes be changed? Brake shoes should be changed roughly every 60,000 km on average, though driving habits and climate can shorten or extend that interval.
How do I tell if my brake shoes are bad? Common signs include a grinding or scraping noise, a spongy or lower brake pedal, longer stopping distances, or the parking brake feeling looser than usual.
Can I drive with worn brake shoes? It's not recommended. Worn shoes reduce braking performance and can eventually damage the drum itself, turning a simple shoe replacement into a more expensive repair.
What is the life expectancy of brake shoes? Most brake shoes last around 60,000 km under normal driving conditions, though harsh winters and frequent hard stops can shorten that lifespan.
What causes brake shoes to go bad? Normal friction wear is the main cause, but riding the brakes, not fully releasing the parking brake, and moisture or salt corrosion inside the drum can all accelerate wear.
How long do brake shoes take to replace? A typical rear drum brake shoe replacement takes about one to two hours per axle for an experienced technician, longer for a first-time DIY job.
What do brake shoes look like? Brake shoes are curved, crescent-shaped metal pieces with a friction lining bonded or riveted along the outer edge, shaped to match the inside curve of a brake drum.
Keep Your Drum Brakes Reliable Before They Grind
Brake shoes wear slowly and quietly until they don't, and catching that grinding sound early keeps the repair simple and the drum itself out of the shop bill. Whether it's shoes, drums, or anything else keeping your vehicle running the way it should, MTX Performance carries the parts to back it up.
