Speed Bleeder on slave cylinder and brakes

The Speed Bleeders are amazing, I have never been able to bleed the brakes so easy and my system was completly new with no fluid in the lines. It worked so good I had to try it on the clutch (slave) new system as well, It was easy and fast.---One question, Which size clutch master gives you a slightly softer pedal the .70 or the .75 ?--I know its been mentioned before but cant remember.
 
larger cylinder will give you softer pedal.(All else being equal, unchanged).
 
I ran into a store the other day that actually stocks them.
On a rack no less.

I found an old post where vettedog says the large cylinder takes 8% more effort ????--------
 
I can see they are nice, but I use a one person bleeder that slips on the bleeder screw, small piece of tubing with a checkvalve on the end. It works fine.

Is it really worth installing the speed bleeders for something you do once a year at best?
 
I don't think I would put them on, just to put them on, but if I was replacing the cylinders and rebuilding the calipers, it would be a nice touch.

I have them on my truck and they are handy.
 
I thought the mathematics needed to resolve the question was elementary school math. The bigger the pump the more effort it takes.
 
I agree also, they are great. Once you've used them, you'll say, this is a great invention, why didn't I think of it!
Have them on the brakes and the clutch slave.

I agree with Vettedog. The bigger the master (assuming the slave stays the same) the more effort it will take to push the master.

I also agree that the math is very simple, but I can see that the concept or theory of hydraulics may not be so simple to grasp. I like to describe it as a 'lever' with the ratio of surface area of the master to slave as the lever ratio. If your master has half the surface area of your slave it takes half a unit of force on the master to get a full unit of force on the slave. If you make the master bigger, say 3/4 of the slave then it takes 3/4 units of force on the master to get one unit force on the slave. The other thing that changes here is the travel required on the master (that is the 'there is no free lunch' part of the thing)

Mr. Vette Dog, by bringing your old post up with your opinion- I was giving you credibility and a compliment, but obviously from your sarcasim you didnt take it that way. Excuse me or anyone else from asking questions that are beneath your intelligence.

That's what she....

Never mind

YIPES! No sarcasm intended; if you read my post about the water pump having the fan attached to it (on a TR6), you would know I realize my fallibility, and increasing spasms of brain [censored]. I deeply apologize for the miss-intended offensiveness of my earlier post.
