Hedume Brake Lining Thickness Gauge 4-Pack — 8‑in‑1 Steel Ruler Set, Color‑Coded 2–12mm

Hedume's 4-pack 8-in-1 brake lining thickness gauge is a compact steel ruler set that lets you quickly measure brake pad material and identify service needs at a glance.

Whether you're a DIY car owner, a mobile mechanic, or running a small workshop, these compact feeler blades simplify brake inspections. The set combines eight common thickness blades color-coded in green, yellow, and red so you can determine pad condition fast. Built from powder-coated 20-gauge steel and riveted together, the gauges are durable enough for repeated checks and small enough to fit in a glovebox or pocket.

How do I use this gauge to check brake pad wear?

Using the Hedume gauge is straightforward: pivot the blade that matches the suspected thickness and slide it into the caliper or alongside the pad to compare remaining material. If the blade seats flush or easily reaches the backing plate, that indicates minimal material left. The color bands give an immediate visual cue for action.

• Select a blade close to the expected thickness (2–12 mm options).
• Insert the blade between pad and rotor or against the pad face.
• Note whether the blade sits flush, protrudes, or stops short.
• Refer to color: green (good), yellow (service soon), red (replace now).

What thicknesses are included and why are they color-coded?

The set includes eight blades with both Metric and SAE markings: three green blades at 12, 10, and 8 mm; three yellow at 6, 5, and 4 mm; and two red at 3 and 2 mm. The colors map to common service thresholds so you can judge safety at a glance without doing math. Having both unit systems ensures you can work with international specifications or quick visual checks.

• Green: 12, 10, 8 mm — likely acceptable remaining pad life.
• Yellow: 6, 5, 4 mm — consider scheduling service soon.
• Red: 3, 2 mm — pad material is low and replacement is due.
• Metric and SAE markings on each blade for precise reading.

How durable and portable is this 4-pack gauge set?

Each gauge is fabricated from 20-gauge steel, powder-coated for corrosion resistance, and riveted to hold blades securely. The compact, layered design folds like a pocket multi-tool, making it easy to carry in a toolbox or glove compartment. The coating and steel construction are intended to withstand regular workshop use without bending or rusting quickly.

• 20-gauge steel blades for stiffness and repeatable measurements.
• Powder-coat finish to resist chips and surface rust.
• Riveted pivot keeps blades organized and prevents loss.
• Small footprint — four sets fit in a toolbox or storage drawer.

Can this gauge be used on different vehicle types and in various conditions?

The Hedume gauge is a general-purpose brake pad measuring tool suited to passenger cars, light trucks, motorcycles, and many utility vehicles where pad thickness checks are needed. Its simple mechanical design works in cold, warm, or dirty environments, though cleaning the pad area before measuring improves accuracy. It's not vehicle-specific, so use it as a quick inspection aid before more detailed diagnostics or brake work.

• Works with most disc brake pad shapes and clearances.
• Useful for cars, light trucks, and motorcycles.
• Portable for roadside or shop inspections.
• Best practice: clear loose debris for accurate seating.

Who is this for: The Hedume 4-pack 8-in-1 brake lining thickness gauge is ideal for DIY car owners who want an easy way to monitor brake wear, mobile technicians needing a fast inspection tool, and small shops seeking a low-cost, durable gauge set. If you want a straightforward visual and tactile method to judge pad life without specialized equipment, this compact steel set offers a repeatable, portable solution.
