Yes another brake bleeding question....

So here is where I am at... I have replaced the rotors, and drums, new pads front and rear. I also upgraded with a new master cylinder and booster from a 1 ton. I have the switched as the cylinder as per the swap write up. In the process I have pulled all bleeders, cleaned and or replaced with new and cleaned the bleed holes in the calipers. etc.

Here is where I am now... I have bleed the Master cylinder and am getting ready to start on the wheels.

My concern it that my proportioning valve is right up next to my MC. when I swapped out/cleaned all my bleeders, I am sure I ran the fluid down. How should I go about bleeding the system now?

Should I hook up the lines from the master to the proportioning valve then let the rear gravity feed. then open the front and let it gravity feed.

Or can I just hook it all up and use the wife to go 1/2 down, open to floor hold etc....

I am just not sure as my lines are close to empty.

Re: Yes another brake bleeding question....

You could try gravity bleeding but it might take a while. I had to do something a little different a while back that worked pretty good. I had a bad wheel cylinder that I took too long to get around to replacing it and had a heck of a time getting my back brakes bled out. What I did was have my g/f tell me when she was pushing on the brake pedal, I would crack the bleeder screw and when the pedal hit the floor she would tell me and I would close the bleeder. We did this quite a few times and got everything bled out nicely.

drain all the fluid , start with one wheel put fluid in a squirt oil gun with a hose hooked to the bleeder fill the gun as needed dont let it run out , pump left front a while then go to right front and pump till it fills the master cylinder , repeat for rear ,,,,,,,,, work's perfect

Re: Yes another brake bleeding question....

Just done a quick search on homemade bleeder an got this. Mine looks a little pretty-er but this will work. I usually run one line back into the master and just bleed, say the back 1st by itself and then bleed the front. Just make sure you keep the bleeder cup and the master full.

Re: Yes another brake bleeding question....

If you are purging the entire system (or have drained it) you'll do a lot of pedal pumping to fill the entire system again.

It's much easier & faster with a one man brake bleeder hose. Only a few bucks, any parts store should have them. There's a one-way check valve to prevent air from entering between pumps.
