The only Perfectly Reliable Brake fluid In Amazon.
Unlike Carlube and Comma brake fluids, castrol's brake fluid has 0% moisture as all brake fluid should have.Btw, I returned the other 2 because carlube has 2% moisture (same as my 4 year old brake fluid) and commas brake fluid broke the scale of my brake fluid tester at above 5%.To help you understand, 3% moisture can lower a brake fluids boiling point by a 100 degrees!Last thing I need is my brake fluid to turn into gas which is compressible while making my brakes feel spongy which actually causes it to not work.But Castrol is the one brand you can put your trust in.

Its yellow!
On first opening the bottle I was a bit surprised to see the fluid was yellow! Most brake fluids start off colourless, and then develop a yellow hue over time as they absorb more water. So they therefore act as an indicator of the age of the brake fluid. As the bottle also didn't have the normal seal you typically find on things like bottles of engine oil, just a seal pad on the inside of the lid, I was immediately concerned that the fluid had "gone off". A quick search however found the MSDS for this product which states that this DOT4 fluid is indeed yellow when new.So far it works as well as the old fluid in my motorbikes brake system (Honda), will be interesting to see what colour it has changed to in 2 years time!
