Re: Blleding Brakes 68 Corvette

Just a reminder: Brake fluid other than (dot 5) quickly removes paint. Be very careful while bleeding.

Good Luck

We have brake fluid flow, finally

I finally have fluid dripping from both bleeders on the passenger rear calipers.
I purchased a Hand cacuum pump at Sears today (like the Mighty Vac)and have fluid movement.
I still am not certain if the master cylinder is functioning properly or not but one thing at a time.
Is there a proven method to convince myself that the rebuild and the resleeving was done properly?
I don't want brake failure as I drive agressively, if I ever get this thing on the road again?
Also, this proportioning valve or distribution block (whatever it is) that is aatched to my master cylinder: how can it have a piston or anything moving since it is a solid block of steel with brake lines connected to it? How did the piston (if there is one) get inside?

Lastly and most important, thank you to each and everyone for your input and support with this problem. It was frustrating to have rebuilt almost the entire car and yet get hung up on something as simple as installing a master cylinder and bleeding brakes.
I have said it many times and will reiterate that I am greatful for the help of all on this discussion borad and would be lost without it.
Thank you all,
Kurt

You need not worry about having brake failure while driving aggressively (or otherwise). Before you take the car out of the garage, you'll be able to tell if the brakes are working properly, or not. If not, then you "go back in" and do whatever's necessary to get it right. You will only get unexpected brake failure if you have a condition like caliper piston air pumping or leaks (easily discerned). A check of the TIR on all brake rotors will eliminate the air pumping possibility.

Believe me, there is a piston inside that "solid steel" distribution block. If there were not, then the'd be no reason for the switch which adorns the top of the unit and to which the wire connects. Distribution blocks, by themselves, don't need an internal piston or any internal parts. However, disribution blocks which are also pressure differential sensing switches do need an internal mechanism. In this case, that's a piston which moves horizontally.
