Tlence Steel Drum Brake Resetting Gauge — 6.5"–14.25" Dual-Scale Caliper, Heavy-Duty Metal

Tlence Steel Brake Resetting Gauge is a heavy-duty dual-scale caliper designed to quickly and accurately measure and set drum brake clearances from 6.5" to 14.25" (160–360 mm).

Whether you are rebuilding brake shoes, adjusting parking brakes, or checking rotor runout, the Tlence gauge gives technicians and DIYers a simple way to transfer internal drum diameters to the brake shoes for precise clearance. Built from solid metal with both imperial and metric markings, it replaces guesswork with a repeatable measurement process that saves time during assembly and prevents multiple trial fittings.

How do I use the Tlence gauge to set drum brake clearance?

Set the inside jaws inside the drum, expand until the scale reads the inner diameter, then lock the wingnut to hold that measurement. Place the outside jaws against the brake shoes and adjust the shoe star wheel or cable until the shoes just touch the outer jaw, then back off to the specified clearance.

• Insert inside jaws into drum and expand to fit.
• Tighten wingnut to lock measurement.
• Transfer gauge to shoes and adjust until shoes touch outside jaws.
• Back off to manufacturer clearance and recheck.

What measurement range and accuracy does this tool offer?

The Tlence caliper covers drum diameters from 160 mm to 360 mm (6.5"–14.25") with both 1/32" and 0.88 mm increments for fine adjustment. The dual-scale face is easy to read, so you can work with metric or imperial specifications without conversion errors.

• Range: 160–360 mm (6.5"–14.25").
• Increments: 1/32" and 0.88 mm markings for precise settings.
• Dual metric/imperial scale reduces calculation mistakes.
• Clear graduations aid repeatable measurements.

Is this gauge durable enough for a busy shop?

Tlence manufactures the gauge from high-quality metal intended to withstand regular mechanic use and occasional knocks. The construction resists bending and keeps the jaw alignment stable so measurements remain reliable over time.

• Solid metal body for long service life.
• Sturdy wingnut locking mechanism secures readings.
• Corrosion-resistant finish for workshop environments.
• Rugged design suits both pro and home garages.

What brake jobs can I use this tool for?

This tool is made for a wide range of braking tasks: drum brake setup, parking and emergency brake adjustments, and quick checks of rotor or shoe relationships before final assembly. It speeds up pre-installation checks and helps avoid repeated drum fits.

• Rear drum brake shoe adjustments.
• Parking/hand brake cable and lever settings.
• Pre-installation rotor/shoe clearance checks.
• General brake maintenance and rebuilding tasks.

Who is this for? The Tlence Steel Brake Resetting Gauge is built for automotive professionals, brake rebuilders, and experienced DIY mechanics who want accurate, repeatable drum measurements without relying on trial-and-error. If you regularly work on vehicles with drum brakes or perform brake rebuilds, this tool simplifies setup, reduces installation time, and improves confidence that shoes and drums meet specification before final assembly.
