Well, I've been having trouble with my linked brakes on my Honda ST1300, and had to break into the system to replace something called a secondary master cylinder...which sticks...often....and then it drags your rear brakes! PITA!

Well, Red and I got it swapped out, and then went to exchange our brake fluid, and then bleed it....simple, right? Nope! Not on your life!

Our first try was a disaster....I couldn't suck up enough fluid and air with my handheld mityvac, just couldn't do it.... Linked brakes are greato, but it takes a lot of suction to flood the system, especially if you replace that complete assembly......

Well, we needed something better, and fast, if we were going to Nassir. We didn't have the scratch for a $300 trick commercial brake machine, but we did have the smarts to utilize our old Hoover vacuum cleaner. We spent probably under $15 on a snap-shut container (Bi-Mart), three barbed hose receptors (Napa), and a plastic pipe elbow, screw in plug, and vinyl tubing (ACE Hardware). I sealed the barbs into the receptacle and the screw in plug with silicon adhesive (Shoe-Goo, actually). We took our vacuum cleaner hose to the hardware store to get a correct fit........ The thing worked like a charm, and probably as good as $300-$400 worth of commercial brake machine.... we went back to my wonderful father-in-law's borrowed garage, hooked it all up, and with Red pouring and me bleeding and our Hoover sucking, we got a firm pedal and a firm lever in under an hour!

Here's our baby below! Try it yourself; it makes it so easy we swapped our clutch fluid as an afterthought!

Glad to hear you got it. I was afraid you'd have to submerge the bike in a tank of brake fluid and shake it.:action:

A wife that lets you use the home appliances is pretty cool. I have to wait till mine goes to visit her parents before I can run my tackle boxes through the dish washer. :)

I'm more of a Eureka guy myself :)



Glad you got it all done!

A little side note -- Don't run a vacuum very long under those conditions. The unit needs the air input to cool itself, and a motor will burn up, or cause pre-mature damage, without air going thru it. Best to make a variable inlet valve (tee), and let as much air into the vacuum as possible, and still have enough "suck" to do the bleed job.

We only run it about 30-60 seconds per bleeder, shut it off in between..... only gonna use it as a brake machine maybe once or twice a year.....if we burn the Hoover up, we'll find another second hand one. Still cheaper than the "Commercial brake bleeding" unit........lol......

But I was thinking that if I ever get an air compressor, I might do away with the Hoover and exchange the plastic pipe elbow for a skinnier T, and blow compressed air through the T....which creates a venturi effect...... some "Commercial brake bleeders" use that system....

They also make cool little vacuums for the aircraft industry that run off of shop air. Those things work great, but you had better have a good air supply, those things use a lot of compressed air.....:cool:

Yep the venturi effect works great. They make bench hold downs for wood workers using the same technique. Once you turn the valve on you can lift the entire work bench with the hold down.

Is it just me... or does that thing look very similar to something my roommate had in his closet back in college!
