when bleeding brake fluid...

does the pedal have to be pumped several times OR
does the pedal just need to go down once and stay down? or both?

if both (which I don't think is the case because it would contradict what type of pump it is), why? if it has to stay down, then will the pedal go down further from the loss in pressure when the valve is open? if so, would it be bad if the pedal went down too much?

I am mainly concerned about the questions in bold. I just want to figure this stuff out before I do it myself. I want to be sure about everything.

it seems like a pretty normal thing to be brought up but surprisingly, I haven't found a sure answer anywhere yet. and the stuff I do find all says different stuff. I think I need to understand how the entire pumping action/system works (and what type of pump it is) to figure this out.

someone please help me! this is driving me CRAZY!

 

Here you go. Courtesy Billman.

I bottle of ATE Super Blue is surely enough to do the entire car. You'll use 3/4 -7/8 of the container.

By trial, I've found the best sequence is RF, LF, LR, RR.

Empty the master with a turkey baster.

Crack the right front bleeder, the level will start to drop. Get it a little lower, but not enough to suck air.

Fill the master to the very top with ATE blue.

Start with the right front bleeder. Attach a clear hose, and let it gravity bleed till it turns blue.

Repeat for the remaining wheels.

You'll have such a great brake pedal from the gravity bleed it will feel like the pedal is welded to the car

I have used this procedure on countless s2ks.

 

thanks! appreciate it

so with the gravity feed, all I have to do is open the valve and watch the fluid come out on its own? if so, that's pretty awesome! but won't that take a while?

will it somehow create a vacuum somewhere in the system since the pedal is still up? how will it work? sorry for having so many questions

 

When you crack the bleeder valve fluid will come out. Yes it takes a little time. Even if you dont use the blue fluid you will see it run clear.

Just don't let it run out of brake fluid. When you are done try it out.
