Vacuum brake bleeder

[ford12]

Hello all.
Can I get some advice from the people in the know.
I bought a vacuum brake bleeder in the hope it would make it much easier to do.
I can not get it to work.
It holds vacuum and easily empties a container of brake fluid in no time.
Problem is it will not suck brake fluid from the bleed nipple, the most I can get out is a couple of drops.
What the hell am I doing wrong ?
Car is a FG mk11 6 cylinder ute.

I'm wondering if the bleeder nipple might be blocked with crud Ford12?

Unfortunately not, brake fluid would flow when the brake peddle was pushed

Sure you got enough pressure?
They generally need around 100psi.

Is this one of those ones that connect to a air compressor?

I bought one too, it sucks balls and doesn't do squat. It sits in the corner gathering dust now.

Hi. try doing it with the lid off the master cyl. Cheers MD

I bought a reasonably cheap one from Sydney Tools and it works fine - WITHOUT the brake pedal being pushed

My one is very similar, looks the same.
I must be doing something wrong.

Usually it sucks around the threads on the bleeder nipple, try only opening it 1/4 of a turn.


or


Try gravity bleeding, open the nipple place a catch container under, make sure master cylinder is full and go and make a cup of coffee or tea. Check the master cylinder fluid level and top up once per wheel. Make a cup between each wheel and remember to go when needed.



Sure it's slow, but we found with the race cars it was the only way to guarantee a complete bleed (apparently drivers don't appreciate coming to the 1st corner and finding no brakes, go figure)




Stay safe

I second this Method, Sure It's time consuming But, It works..

Vacuum bleeders work well in dealer situations where time is critical to do multiple operations. Pumping fluid via the pedal is the best. although requiring more people to accomplish.

I wonder if it has something to do with the ABS system

[Trevor 57]

ABS is electronic not hydraulic

ABS is an over-ride system and only works when your foot is firmly planted on the brake pedal with the car running

ABS is both electronic and hydraulic.

electronic activates hydraulic, they are not interchangeable, I can back it in your car doesn't have electric brakes
