Brake Fluid

[RBYM]

Does our usdm fiesta st use regular or LV dot 4?

The factory fill is DOT 4 LV, but many have used regular DOT 4 fluids, and DOT 4 racing fluids, especially if they live in hot climates, and/or open track, do hard 'canyon runs', etc. with their rides.

Some claim that one needs the LV fluid in order for all of the various 'nannies' (ABS, ESC, TC, TVS) to function properly on our platform (if that is critical to you), but I do not know if this was ever empirically confirmed or not.

I may go to a higher temp DOT 4 (like Ate Type 200) or a DOT 4 racing (like Endless 650 or the like) just to try and stave off the dreaded clutch pedal sticking to the floor syndrome next summer (since it only ever happens to my slave cylinder in the heat).

Thank you, just ordered some motorcraft dot 4 LV.

The low viscosity (LV) fluid is thinner which helps reduce the amount of fluid cavitation that occurs when the ABS pumps activate. This translates to smoother, less delayed and quirky feel, response. I use it in any DOT4 system that has an ABS pump.
