Repco Brake Fluid Tester - RST239

Repco Brake Fluid Tester

Your brakes are only as strong as your brake fluid. As DOT 3, DOT 4 and DOT 5.1 fluids age they absorb moisture, lowering boiling point and inviting fade, ABS issues and internal corrosion. The Repco Brake Fluid Tester gives you quick clarity on fluid condition in seconds, so you can decide to leave it, bleed it or schedule a full flush—before your vehicle’s stopping power is compromised.

Using it is simple: dip the probe and press one button. Colour-coded LEDs instantly show moisture levels at a glance, taking the guesswork out of maintenance. It’s compatible with DOT 3, DOT 4 and DOT 5.1 systems, covering most passenger cars, SUVs and light commercials. An automatic shut-off conserves power and the included AAA battery means it’s ready to work straight out of the box. Perfect for pre-trip checks, used-car assessments or speeding up workshop diagnostics.

Compact and workshop-friendly, this Repco specialty tool helps protect master cylinders, calipers and ABS pumps while saving you time at the vehicle. If you value confident braking and fewer comebacks, add this tester to your top drawer and make fluid checks part of every service.
