All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Liberator hand trucks fitted with automotive-style double disc brakes. The brake handle on the upper grip squeezes calipers on both wheels at once — same fade-free, all-weather, wet-friendly braking technology used on every car since 1965.




Disc brakes cost more up front. They’re worth it when stopping power has to be predictable on every pull. Below is the side-by-side decision.
| Factor | Disc brake | Tread brake |
|---|---|---|
| Stopping power | Highest — automotive caliper | Moderate — shoe on tread |
| Wet weather | Excellent | Reduced (rubber on water) |
| Lock-up risk | Low (modulated pressure) | Higher on sudden pull |
| Wear point | Pads replace every 18–24 mo | Brake shoe wears in months |
| Maintenance | Pad replacement, occasional bleed | Shoe swap, simpler |
| Best for | Stair routes, grades, 500–600 lb | Flat warehouse, 300–500 lb |
Each wheel gets an automotive-style rotor and caliper. Squeezing the brake handle activates a hydraulic line that closes both calipers simultaneously — not sequentially — so the truck stops square instead of yawing. The spring-release on the handle returns to full brake pressure even when the operator pulls off-center on a heavy load.
Buy disc if any of these apply: (1) stair routes — you need predictable hold mid-step, (2) outdoor or wet routes — tread brakes lose grip on wet rubber, (3) loads consistently above 500 lb, (4) grade exits (loading dock to truck bed) where momentum builds, (5) operator turnover — disc’s modulated feel is more forgiving for new hires than the lock-up risk on tread brakes.
