Carlyle Boiling Point Brake Fluid Tester (CBFT180)

Description

Genuine Carlyle · Part no. CBFT180

The Carlyle Boiling Point Brake Fluid Tester measures the actual boiling point of the brake fluid in a car's reservoir, so you know whether it is fit to keep or due for a change. It works with DOT3, DOT4, DOT4+ and DOT5.1 fluid, runs on 12V, gives a result in about 30 seconds and shows it on a backlit LCD.

Good to know

• Why test the boiling point? Brake fluid absorbs water from the air over time, which lowers its boiling point; fluid that boils under hard braking gives a spongy or sinking pedal.
• What reading means a change? The minimum wet boiling points set for brake fluid are 140°C for DOT3, 155°C for DOT4 and 180°C for DOT5.1; fluid testing below its grade's figure is due for a change.
• Can it test any brake fluid? It lists DOT3, DOT4, DOT4+ and DOT5.1; DOT5 silicone fluid is a different type and isn't on that list, and the two types must never be mixed.
• Does a good reading replace the service schedule? No; many carmakers set brake fluid changes at fixed intervals, so follow the handbook as well as the test.

Which one?

For reading ABS and engine fault codes rather than testing fluid, the Topdon ArtiDiag600S Diagnostic Checkers With Lifetime Update (ARTIDIAG600S); for electric parking brake service on a pad change, the Topdon ArtiDiag900 Lite 8in Wireless Diagnostic Scan Tool (ARTIDIAG900LITE).
