Automatic brake bleeder

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Sorta.  A couple of months ago I bought 1 of them H.F. brake bleeders.  I finally got the rusted thru brake line replaced on the 05 Chevy on Sat**day.  Today I got to try out this kit.  There's a bottle you fill with brake fluid, invert it with an adapter it sets in the opening of the master cylinder.  Then you loosen up the bleeder screw and snap a rubber line on the bleeder screw.  You hook an air hose to a mechanism, it creates a vaccume in a bottle hooked to the bleeder screw.  It sucks brake fluid from the master cylinder to the wheel cylinder.  The upside down bottle automatically refills the master cylinder.  I set there from 11:15 this morning till 3:45 this after noon watching this thing sucking brake fluid/air outta the brake system from the right rear wheel.  Constantly refilling the bottle on top of the master cylinder.  At that point I got tired of messing with this thing, unhooked everything, tightened down the brake bleeder put the dang tires back on.  And would you know it, the dang brakes worked.  I cannot imagine where the dang air bubbles were coming from, unless it was being sucked in around the threads on the brake bleeder screw.  If I'd had a 6 pack I might a drank a couple.  What a day.      at least the brake bleeding outfit works.

	Only need the bleeder open enough to feed air/fluid, once a steady state of fluid and done, too much vacuum and will suck around the threads.

	I decided that was the case with my hand operated vacuum pump. Drawing air through the threads.

	I always wrap the bleeder screw threads with teflon tape as used on pipe joints and it stops air bleeding in around the threads. Also seems to keep the bleeder screws from rusting to the wheel cylinders.

	Phil that sounds like a good idea. If I ever work on brakes I will try to remember that. Way to go Tom on getting the brake line fixed. I have never done that. Mike

	If using the teflon, is there ever a problem with the bleeder screw loosening later?

	Never had one loosen on it's own, and been doing it for a long time.

	With persistence the bleeder can cover other mistakes. I got this old 72 Chevy 4x4 , the first year Chevy put front discs brakes on a 4x4. Neighbor had since it was a year old, used but not to bad abused. Anyway had to replace rubber hoses on front brakes, and the sobs just did not bleed. Not being a natural born wrench turner like O'l Joe and a bunch of you I got my buddy that knows. He looks and say what you been doing under here? The calipers had been switched from side to side and where up side down. Then my brain kicked in, the neighbor had been playing with a automatic brake bleeder and was having no luck some years before when doing brakes on the old Chevy. So you can bleed brakes with the bleeder up side down if you keep after it long enough. Edited by Ray54 - 18 Nov 2020 at 10:35am

	It was the first time I used it, took it outta the box and actually read the directions. I had the air pressure turned down to 40 lbs. Was as low as the regulator would go. Wish I'd ask on here first. I could a finished up in an hour and got my afternoon nap in.
