Brake Fluid

[LandRobert]

Hello Everyone,

So, I decided to replace the brake fluid on my 2015 LR4. I did a complete flush with a manual vacuum pump. The thing is that I believe I used the incorrect brake fluid. The workshop manual specifies shell donax yb dot4 esl (ISO 4925 Class 6 viscosity 750 mm/s2) which is nearly impossible to get so I went for the Pentosin Super DOT 4, after doing all the work I realized that Super DOT 4 is specified as ISO 4925 Class 4 (viscosity 1500 mm/s2) and what was required was ISO 4925 Class 6 which is a lower viscosity fluid. So I should've used Pentosin Super DOT 4 LV. Atlantic British sells ATE SL for the LR4 however I believe the correct fluid should be ATE SL.6. They seem to no longer offer Castrol DOT4.

The question is, should I try to empty the whole brake system and pour in the correct fluid or just leave it as is and use the correct fluid on the next service?

@txfromwi I believe you used Castrol DOT4 on your LR4 which is ISO 425 Class 4, any performance issues with that?

What would you do?

Thanks

If I were that worried I'd buy Land Rover brand and let them stick it to me. Fresh DOT 4 from a reputable brand is good enough. If I had a worry its the brakes in general because they don't work as well as I'd like. A big brake kit would fix that, AP Racing or Brembo monoblocks front and back. But the facts are nobody cares so there is no market for them.

You won't notice any difference between the fluids.
DOT 4 meets the requirements.

how much brake fluid would you need to purchase to do a full flush?

anyone have a good video or manual on how to do it?

It should take about 1 liter if you're careful and try not to spill any fluid, I bought 2 liters just to be safe.
