Gravity Bleeding


Have you tried putting blocks on the pedal so the poor dog can reach them.
She’s only interested in the accelerator. It’s all “Go, go, go!” With her.
 
I fixed it for all of you "English teachers" out there.

For a crowd that uses "to" instead of "too" all the time, you guys really know how to focus on the issues.

at least I spelled it right.
 
Back in the old days when I was a kid and couldn't afford any new parts I had to rebuild everything
So I did my share of brake masters and figured out how they worked, wasn't magic anymore, lol
And the same for wheel cylinders, no such things as calipers in my world at that time, lol, drums all around

So I would have to pull off a wheel cylinder, hone it, put in new seals as needed and reassemble, so brake lines were disconnected for awhile

I found if I used a stick against the seat to press down brake pedal a bit that would close off the Master cylinders reservoir, kind like putting your finger over the end of a straw so fluid doesn't leak out
Really slowed down the leaking fluid and of course plug the hose as best you can, lol

Gravity bleeding got the air out usually

If it didn't I built a "power bleeder", well kind of
Block of wood with an air valve added, valve part removed, 2 C-clamps
Inner tube, yes the thing that used to be inside tires, lol
Would use a hand pump to pump up the inner tube to 5 or 6psi, not much
Then put a hose between the two
Power Bleeder............lol
Could usually do all 4 wheels without adding fluid or pumping up inner tube again :)

Mom was my "power bleeder" for awhile but told me to "figure something else out", so I guess she invented it
Like they say "Mother is the necessity of invention", or something like that



Awesome.. my bronco is drums all Around still.....gravity bled after relining last time... I suspect proper bleeding would make it better....but. Works fine so I let her ride for now.
 
I got rubber hoses that fit over the bleeder, and the hoses are electric stretch taped into small plastic jugs that catch the fluid while it gravity feeds, first the back two, then the front
 
I've always bled brakes by myself, including the 68 Mustang that I just replaced wheel cylinders, hoses, the master cylinder, and every inch of steel line. I bench bled the master before installing it, then cracked the wheel cylinder bleeders open one at a time and slowly pumped the pedal. I stuck a hose on the bleeders and ran it into a jar with a little fluid in the bottom so air wouldn't get drawn back in as the pedal rose. I'd pull the hose out of the fluid once in a while to see if it was gravity bleeding, once fluid dripped out steadily I was done with that one. Having a helper would make it a little faster but I got it done.
 
I just changed master on my truck. Overfilled the reservoir, opened an bleeder, went back gave the pedal 4 pumps, refilled reservoir, 4 more then closed the bleeder. Rinse and repeat. Not the same as it was before. But will still lock up all 4. :dntknw:
