Repco Disc Brake Caliper Tool 200 - 400mm

When you need to know exactly what brake rotor your vehicle is running, you don’t want to pull a wheel just to measure it. This Repco disc brake diameter gauge lets you confirm rotor size through the spokes in seconds, so you can quote the right parts, plan a brake job with confidence and keep vehicles moving through the workshop or driveway.

With a wide 200–400mm capacity, it covers most passenger and light commercial rotors you’ll see. The generous 265mm reach slips past deeper rims and larger calipers, and the easy-to-read metric graduations deliver clear, repeatable numbers at a glance. The result is faster inspections, fewer ordering mistakes and zero guesswork between rotor options—especially handy when you’re comparing upgrade sizes or confirming fitment before parts arrive.

Built for everyday use by techs and keen DIYers alike, the Repco Disc Brake Caliper Tool turns a fiddly task into a quick, accurate check without removing wheels. Add it to your brake service kit and make smarter decisions sooner—because the right measurement up front makes every brake job smoother, quicker and more professional.
