Hedume Brake Lining Thickness Gauge 4-Pack — 8-in-1 Steel Pocket Rulers, Color-Coded mm/SAE

If you maintain vehicles, a fast, reliable way to check brake pad wear saves time and prevents surprises. This Hedume set contains four pocket-sized gauge tools, each made from powder-coated steel and riveted for durability. The blades are color-coded to indicate service condition at a glance and include both metric and imperial markings so you can read measurements the way you prefer.

How do I use these gauges to check my brake pads?

Slip a gauge blade into the caliper opening or against the pad material until it contacts the backing plate, then read the marked blade that fits flush. The color of the matching blade tells you whether the pad thickness is acceptable, due for service, or overdue. Using the correct blade prevents guesswork and lets you decide on replacement timing safely.

• Insert blade between pad and rotor or into caliper slot for a clear fit.
• Match the blade thickness to pad material—green means good, yellow means check soon, red means replace.
• Read metric (mm) or SAE markings printed on each blade for exact thickness.
• Repeat across multiple pads to compare wear evenly.

Which measurements are included and why are colors important?

Each gauge blade is stamped with both metric and SAE values so you can verify pad thickness in millimeters or common imperial sizes. The set divides blades into green, yellow, and red groups to simplify decisions: green indicates ample material, yellow signals approaching service interval, and red highlights critical wear. This visual system lets you act quickly during inspections without consulting charts.

• Green blades: 12, 10, 8 mm for safe remaining pad life.
• Yellow blades: 6, 5, 4 mm to indicate planned service.
• Red blades: 3, 2 mm for pads that require immediate replacement.
• Each blade marked in both mm and SAE for universal compatibility.

What materials and build quality can I expect from the Hedume gauges?

These rulers are stamped from 20-gauge steel and finished with a durable powder coat to resist chips and corrosion. The blades are riveted together so they pivot smoothly and stay aligned during repeated use. Tough construction makes them a dependable tool in a mechanic's toolbox or a DIY enthusiast’s glove box.

• 20-gauge steel for structural stability and flatness.
• Powder-coated surfaces in red, yellow, and green for visibility and protection.
• Riveted pivot assembly for long-term durability and easy access to each blade.
• Compact form factor for pocket or tool-roll storage.

How will this tool speed up my inspection routine?

By giving an immediate, color-coded readout of pad thickness, the Hedume gauge removes the need for guesswork and eliminates repeated measurements with calipers. You can quickly screen all four corners of a vehicle during a service check, flagging only those wheels that need more detailed inspection or replacement. The portability and clear markings reduce inspection time and improve maintenance consistency.

• Color-coded decisions cut inspection time under routine checks.
• Multiple blades let you test various thicknesses without swaps.
• Small, lightweight design allows inspections wherever the vehicle is parked.
• Dual-unit markings avoid conversion errors when planning parts orders.

Who is this for: The Hedume 4-pack is suited to professional technicians, shop owners, and vehicle owners who prefer a quick, visual method to assess brake pad condition. If you want a durable, easy-to-read tool for regular safety checks or pre-trip inspections, this set offers clear measurement options in both metric and SAE formats and fits easily into any tool kit.
