You don’t get much for 6-quid nowadays but with Silverline such a small amount could very well save your life. This easy-to-use brake fluid tester is a simple bit of kit designed to tell you when your fluid has absorbed too much moisture and could do with a change.

The thing about brake fluid is that it’s hygroscopic meaning it will suck water from the air over time. What with water being compressible (unlike the actual brake fl uid), it’s easy to see why you really don’t want it in your braking system.

With it’s 3-colour LED display, you just dip this tool into the reservoir and it’ll quickly tell you if your fluid is still up to scratch.

Everyone should have one of these, a possible life saver – it should be the law!
