Title: Brake Bleeding Tool
Post by: Bengt_Phorqs on December 06, 2009, 07:12:22 PM
I seem to recall a thread within the past six months about bleeding brakes and using an aftermarket tool.  Did a search and can't find the thread.  Does anyone have any recommendations about such a tool to make it easier?  Normally bleeding brakes isn't such a chore but it kind of takes three hands to do this.  (Kind of like tuning the drones on my bagpipes).

IIRC, Mike, the brake bleeding chat was in a multi topic thread chit chat.

If you have a MityVac, after draining out and flushing the old brake juice, you can refill from the brake bleeder nipple UPWARDS into the reservoir. No air trapped at all and it's a one-man job.

There is also a product called 'speed bleeder', it's a bleeder screw, with a spring loaded check valve .

Only have to connect a hose to the bleeder, and open it up and pull the brake lever .

I want to bring over my camcorder when you try to force fluid from the nipple up to the MC with a Mity-Vac, should be really entertaining!  To do this you have to make an adapter to go on top of the MC, apply vacuum and suck it up.  With just the Mity-Vac you fill the reservoir and pull it down and out the nipple.No draining/flushing involved, just empty the reservoir with a turkey baster, put teflon tape around the nipple threads, attach Mity-Vac, fill reservoir, and suck away.  When the fluid coming out turns clear (or whatever color fluid you use) you know you are done...

I used a Mity-Vac as did Justin and bled the brakes on my bike in a few minutes.  That's the way to go.

Mighty vac and the HF cheapo version do a nice job. Also at your local grocery / kitchen gadget store look for a large syringe used to inject marinade into chicken and such. Works a treat to force fluid up from the bleeder.

Yea, I just chatted with Bengt and it appears I've given incorrect 2nd - 3rd hand info off my Cabriolet list. My bad...

I did use a model airplane glo-fuel rotary hand pump to fill the aircraft's brake lines and reservoir from the bottom up. That worked slick.

Here's a photo of my $6.00 DIY pressure bleeder that I use on the Cabrio's brakes. I confess, I have a MityVac and it's still in the package.     Monte

MiyVac can do pressure as well as vacuum,but still wouldn't pump fluid.You can get pressure bleeding pumps that bleed from the nipple to the master cyl - I use a big horse syringe to pump fluid up.I've been looking at drench guns,I reckon they would work well as a reverse flow bleeder.
