Brake/Diff Fluid Capacity/Type

[hemi_fan]

I'm doing Cobra brakes on my car and have to pick up the fluids later today. What is the brake fluid capacity for a mustang approximately? (It'll have 95 Cobra MC and 03/04 Cobra brakes)

Also how much differential fluid do I need, and should I go with 75w140 or 75w90?

Thanks

Also, should I pick up a new gasket for the diff cover or use silicone?

75w-90...a little under 2 quarts. Make sure you get friction modifier from ford if the fluid you get doesn't have it. You can use RTV to seal, but i usually give 1-2 hours for it to set up before filling diff. But i've filled right away as well with no issue.

Brake fluid...the large bottle worked well for me. You can always buy several small bottles and return what you don't use.
