Brake Bleeder Mishap
I was a happy user of a Motive Products' Power Bleeder system. However, it decided to malfuntion today sending ATE Super Blue in multiple locations today. The brake fluid came out through the top of the bleeder via the pump stem at about 13 PSI. Has this happened to anyone else? It's slightly disappointing to see brake fluid flowing out of the bleeder and onto everything else in sight. Dan

Was the cap on tight? Is the seal cracked? These are the only things I can think of. When I use the Motive I put it in a heavy duty garbage bag just in case I screw up. So far it has never happened to me, but an ounce of prevention.....

Dan,
As an afterthought - after you emptied the bleeder, did you try pumping it up DRY to hear where air may be escaping? And will you be at Pocono this weekend? If so, hope you have your brakes bled correctly by then - don't need the worry of you not being able to stop behind me! *G*

For all you guys thinking about the Power Bleeder. Get it! Love mine. Bleed your brakes in 5 minutes. Very easy. Don't know what went wrong with Dan. Think he did not lock the handle.

Speed bleeder nipples. Self contained. Goes everywhere you go because they are screwed into the calipers. Two years of bliss since putting them in. All I need is a wrench and some old can or bottle to dump the fluid in.

Two things -
First, I use speed bleeders as well. They are basically a bleeder valve with an internal check valve which prevents air from being drawn back in on the brake release stroke.
Second, At VIR I used the Power Bleeder in conjunction with the speed bleeders (since those are the bleeders that I have). Worked well although the speed bleeders do not pass fluid at the same rate as conventional bleeders and the pressure used with the poser bleeder is significantly lower then the pressure exerted on the brake pressure stroke. Using this method I did experience the failure that sprayed fluid everywhere. This was caused by misalignment of the rubber washer in the power bleeder top. Fluid choose the path of least resistance, around the cap. Paper towels contained the spill.
Observations - fluid only trickles through a speed bleeder when used with a power bleeder with approximately 10 psi. Spring in the speed bleeder valve must cause a restriction in the flow. Check the alignment of the rubber washer inside the cap on the speed bleeder before pressurizing. Plastic trash bag overflow containment sounds like a great idea.

I'm with Wayne, I built one of the garden sprayer bleeders and it works great!
I also have speed bleeders so after I pump it up, I go to the right rear caliper(furthest away) and turn the speed bleeder about a quarter turn watch for clean fluid and turn and tighten speed bleeder. Viola!!
then left rear, right front & left front last. So Eaaaaaasy
One note, watch for to much pressure when pumping up garden sprayer you only need about 10-15 lbs of pressure. The first time I did it fluid started to come thru the cap threads due to too much pressure.

I tried using the pressure bleeder tonight and at 10 psi, the brake fluid in the bleeder came out the reservoir drain tube (what a mess by the spare tire!). I'm guessing I have to plug this port prior to using the pressure bleeder. Anyone else had this problem?
