From: tomasz.kk on 28 Nov 2007 14:40 i like the idea of vacuum bleeding but it didn't work in my case. I used vacuum from the intake manifold, just had to route long hose to the bottle, and then the other hose to the brake bleeder. like in this topic: http://forums.mg-rover.org/showthread.php?t=161765 With the engine running, a little more then idle the vacuum was very strong, but all i could suck out was the air, which went into the caliper through the thread of the bleeder and then was coming out through the bleeder hole into my bottle. Anyway two person method, one in the car pumping the brake pedal, and the other person collecting the fluid works the best for me. Recently i bought at rockauto the brake bleeders with one-way valve, i haven't tried them yet but they suppose to make the job a walk in the park! These are for Ford vehicles, i don't know if they are available for other brands. http://img404.imageshack.us/img404/8163/dscf0710gb5.jpg

They work good BUT you need to make real sure that you keep them from getting rusted and full of crud. I use them on many of my vehicles. -- Steve W.

Some pipe tape can mitigate this, but pressure bleeders always work. Bleeding by pumping the brake pedal can wipe out an old master cylinder as the seals travel over long-unused sections of the bore. I've had this happen on at least two cars that I can remember, possibly more. In a pinch, if you have to bleed and don't have any equipment, I'd stick a 2x4 under the brake pedal to limit its travel so this doesn't happen. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |
