Review: Top product - Easy to use. No leaking, good price and quality oil as expected
Review: The only Perfectly Reliable Brake fluid In desertcart. - 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.

## Questions & Answers

**Q: is brake fluid high viscosity mineral**
A: This is fully synthetic dot 4 brake fluid.

To the other answerer, you can also buy mineral brake fluid (popular among bicycle braking systems).

**Q: does this product work for a ford galaxy tdi 2002 model  1.9 engine?**
A: Yes, it's fine for that.

**Q: can this be used on a landrover deffender none abs**
A: It depends on its age (model) and what brake fluid has already been used. You need to check if it has silicone fluid which is not compatible with DOT4. Older models are likely to have this hydroscopic fluid

**Q: Hi is this ok for a 2018 Mitsubishi Eclipse cross**
A: You should check with a Mitsubishi dealer to be safe
