Brake fluid

[stevnoof]

I'm upgrading the base model brakes for the 4 piston and 14in rotors what kind of brake fluid does the car use?

Per the Owner's Manual:

Brake fluid: WSS-M6C65-A2
Motorcraft DOT 4 Low Viscosity (LV) High Performance
Motor Vehicle Brake Fluid
PM-20

Thanks for response

U think it's alright if I use any dot 4 fluid? Not sure if they have motorcaft at the store and I just got the brake 3 days early!

Think there are some higher boiling point fluids you might want to use.
Since we are sort of in the same boat let me check with the NASA instructor on a suggestion or two. Or you can post in the track area. They lookin good?

Yea they are huge. A little dirty but I cleaned them up a bit. I just picked up prestone dot 4 synthetic I hope that works well.

DOT 3/4 are compatible with each other, and as noted, with each successive number comes a higher boiling point. DOT 5 fluid is available, with the highest boiling point, but it contains silicone or something similar (it's been a while since I looked at it) and isn't backwards compatible with DOT 3/4.

As far as the Prestone being compatible with the Ford fluid, I'd think it would be, but I would check the bottle to see if it's specifically states that it's compatible with Ford Standard WSS-M6C65-A2. I wasn't even aware that Ford used a LV fluid for the brakes.

Castro SRF IMO. Past that, Motul.

A good one to use is motul 600, it boils at around 400 or so degrees, they do have motul 660 that has even higher boiling point, but needs to be changed more often, max once per year, I do that anyway for every track season.
Also ATE 200 slightly lower boiling point.

That was from my classroom instructor...take it for what it is worth. Better then me giving suggestions.

Cool I use motul oil

Pentosin DOT4 LV (low viscosity brake fluid) is the same as the factory Brake Fluid. Available in most parts store chains. I wouldn't suggest running anything else unless you are upgrading to a racing fluid.

LV fluid due to Advance Trac and ABS in case of cooler climates. It has a very high dry boiling point of at least 509F and a wet boiling point of at least 338F. Pentosin I believe supplies the Ford Fluid, all the specs are identical.

I ended up adding about 6oz of prestone synthetic dot 4 to what was already in there. Everything feels fine

My track instructor recommended Motul RBF 600, he said using anything else would be foolish. I have to switch mine out myself I cooked the stock fluid on my base model brakes.

Castro SRF IMO. Past that, Motul.

SRF is over kill for 99% of the cars out there.

I use Red Line RL600 fluid.
