Total Lock vs Side Brake vs Face Brake Casters
A caster brake has one job: keep a loaded cart, bench, or tower where you parked it. Brakes don't all hold the same way, though. Some lock only the wheel, and some lock the wheel and the swivel together. If you pick the wrong type, a "locked" cart can still swing, drift, or pivot when someone leans on it. This guide compares the three brake styles you'll see most often (total lock, side brake, and face brake) so you can choose the right one before you order.
Overview: What Each Brake Actually Locks
The key question is what the brake holds. A swivel caster has two motions: the wheel turns on its axle, and the whole fork turns on the swivel raceway. A brake that stops only the wheel keeps the cart from rolling, but the fork can still turn. A brake that stops both motions makes the caster act like a fixed foot.
- Total lock brake: one pedal locks both the wheel and the swivel. Of the three, it's the most stable.
- Side brake (side lock): a lever or cam mounted beside the wheel presses against the wheel to stop it from rolling. The swivel stays free.
- Face brake (face contact): a pad, usually tightened with a thumb screw or small lever, presses against the face of the wheel to keep it from turning. The swivel stays free.
Decision Table: Total Lock vs Side Brake vs Face Brake
| Feature | Total Lock | Side Brake | Face Brake |
|---|---|---|---|
| Locks wheel | Yes | Yes | Yes |
| Locks swivel | Yes | No | No |
| How it's applied | Foot pedal | Foot or hand lever | Thumb screw or hand lever |
| Speed to set | Fast, one step | Fast | Slower (screw down) |
| Stability when pushed sideways | Highest | Moderate (fork can pivot) | Moderate (fork can pivot) |
| Best for | Workbenches, scaffold towers, medical/lab carts, toolboxes | General shop carts, stock carts | Equipment that stays parked for long periods |
Total Lock Brakes: When You Need a Rock-Solid Stop
If people will work on or against the load, use total lock: grinding on a rolling workbench, climbing a scaffold tower, or pushing a drawer shut on a loaded toolbox. Locking the swivel keeps the cart from "walking" as the fork rotates under side loads. Our 5" scaffold rolling tower caster uses a total-locking brake that stops both wheel and swivel. Our 5" x 2" all-steel caster set pairs two rigid casters with two total-lock swivels and is rated up to 1,000 lbs per wheel.
Side Brakes: The Everyday Shop Choice
A side brake is simple, easy to reach, and usually the lowest-cost way to keep a cart from rolling. It works well for stock carts, parts carts, and platform trucks that get parked against a wall or rack, where sideways pivoting doesn't matter. Its limit is that the swivel still turns. If the cart gets bumped from the side, the brake holds the wheel but the cart can rotate around the caster.
Face Brakes: Set-and-Forget Holding
A face brake uses a pad tightened against the side of the wheel. It takes a few seconds longer to set, but it holds steadily once it's tight, so it suits machines or fixtures that move rarely and stay parked for days. As with a side brake, the swivel stays free.
Applications
- Rolling workbenches and welding tables: total lock on the swivels and rigid casters on the other end
- Scaffold and rolling towers: total lock on every caster
- Hospital, lab, and food-service carts: total lock with a non-marking wheel
- General stock and parts carts: a side brake is usually enough
- Parked machinery and fixtures: face brake or total lock, often backed by a separate floor lock
Building the Right Brake Set
Most carts don't need a brake on every caster. A common layout is 2 rigid + 2 swivel with brake: the rigids track straight, and the braked swivels at the handle end let you steer and lock. When you need the most stability, or when the cart turns in place, choose 4 swivels with brake. Many HYW caster lines come in both layouts. You can find them in our 6" caster collection and the full material handling collection.
For washdown or corrosive areas, our Series 40 stainless steel caster (4" x 2" non-marking rubber, 400 lbs per caster) comes as a Swivel with Total-Lock Brake (part no. 40-40S-A1-INF-TB(STS)). It pairs with the matching rigid and plain swivel versions.

FAQ
What does "total lock" mean on a caster?
A total lock brake locks both the wheel's rotation and the swivel's rotation with a single pedal, so the caster can neither roll nor pivot.
Is a side brake enough for a rolling workbench?
It will stop the bench from rolling, but the swivel can still turn, so the bench may shift when you push on it from the side. For benches you work on, total lock is the better choice.
How many casters on a cart should have brakes?
Usually two, on the swivels at the handle end. Use four braked swivels when the cart must be fully stable or needs to turn in place.
Do brakes change the caster's load rating?
Always go by the load rating listed for the specific caster and configuration you buy, and size the set so the combined rating comfortably exceeds the cart plus its load.
Safety note: Always set brakes before loading, unloading, or working on mobile equipment. Inspect brake pads, pedals, and swivel locks regularly, and replace worn casters right away. Never use caster brakes as the only restraint on slopes or ramps.
