Reddit reviews Motion Pro 08-0143 Hydraulic Brake Bleeder

re Mike's suggestion, I bought this kit and it helped immensely https://www.amazon.com/gp/product/B000MXW2EM/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

Obvious one but check to see if all your connections are tight. I was going crazy trying to bleed my dirt bike before I realized there was a fitting in the middle of my aftermarket brake line that needs to be tightened down (it was there so you could loosen and spin the fitting at the caliper).

Also I have a vaccuum bleeder and one of these and I like this little $10 check valve better honestly.

I used to always go the mighty vac route. It works but I now use the Motion Pro check valve for my changes.

They make it easier to do this without help. While the Mighty Vac lets you pull the fluid out fine, unless you keep a close eye on the reservoir or have a helper keep it topped off, you can suck it dry and you have to start over. With the check valve you just pump out the fluid. They also make one with an integrated socket. They are nice when they fit. On the Honda ST1300, it doesn't fit on all the bleed points because of where they are positioned on the caliper and interference from other hard parts like the fork. So the original like what is linked above is more universal and works better.

Also be sure to change your pads before flushing the fluid. If you do it in reverse (fluid then pads) when you push the caliper pistons back you can overflow your reservoir making a big mess. So change the pads first, seat them by pumping the brakes, then do the fluid topping off to the proper level.

I don't think this is the case with a Vulcan but some bikes have multiple bleed points and they have to be done in a certain order. This is the case on the ST1300. Off the top of my head there are something like 7 bleed points and if you screw up the order you will have air in the lines. This is because some bikes like that have linked brakes where it actuates front and rear brake no matter if you use the brake lever on the bars or the foot brake. ABS systems can also cause more complexities in the process but not in every case. The process on the ST1300 is the same if it is ABS or not.

Yea. I use this and just duct tape one end to an empty water bottle . Gets the job done in like 30min
