Thanks Denny & everyone else for sharing info on these. Good to hear the opinion of people who are actually using them. I am going to our local Napa Store to pickup a set of these. I have some ordinary bleeders to compare with for size & thread comparison.
Very ingenious invention!
The vacuum booster helps the brakes reach very high pressures, & produces maximum braking force on all four wheels. The pedal,can produce 1,200 to 2,000 psi of pressure in the hydraulic brake system.
I've been doing a complete frame off on my 51 Pickup for 6 years now and getting anxious to hit the road next summer. Safety first has always been no 1 with me.
Love the Stovebolt Site
