How to bleed brake fluid that looks the same

[zeddzik]

So I'm preparing for a track day happening this weekend and I'm replacing my current stock fluid with Motul RBF 600 fluid. The only problem is that I have no clue when to stop bleeding the brakes as both my current fluid and the new fluid both look the same. Do you guys know about how many pumps of the brake pedal are needed per corner or is there another way of knowing when to stop?

Motul is blue? If whatever you have is the same color, you have to measure the volume as you flush...

I would think you would need to know the capacity of the system to use a measured volume as a guide. I don't think I'll volunteer to drain my system wheel by wheel to figure it out. =)

You'll have to bleed the whole clutch system as well, right? Since they share a reservoir?

Isn't there a number that Ford states the volume is? If the color is your guide, add some food coloring to the mix....

Suck the reservoirs dry from the top, that'll make it easier.

Regular food coloring is water based. Not a good thing to start with. Someone suggested that a permanent marker could be used to color brake fluid, but I haven't tried it.
