Bleeding Brakes
Hello to all,
Thought I would tap into the "Brain Trust". Getting ready to put brake fluid into the system. What are we using to pressurizing the system? I think I should fill from the calipers. Any hints would be appreciated. |
Not pressure, vacuum
Go and get a mighty vac or something similar. Attach to reservoir, attach tube to bleed screw on caliper, put tube in fluid, draw a vacuum and open the bleed screw...
|
I use a pump type oiling can from the hardware store, slip a tube over the nozzle and fill from the caliper on up.

I use the ATS Blake bleeder tank which looks like a glorified garden sprayer tank.
![]() Many have rolled their own. The hose has a quick release and comes with a couple fittings to mount to most calipers. You attach the tank to the bleeder and run a hose out of the top of the reservoir to catch any overflow. With the tank connected to the bleeder and the tank's valve closed, you pump the tank up, open the bleeder, then open the valve on the tank. The pressure forces fluid from the tank to the reservoir pushing all the air out along the way. Takes me less then 10 min to do both sides. |
large disposable syringe from farm supply place (50ml from memory) and a piece of vinyl tubing, push up from caliper bleed screw, my matco set up takes 1 full syringe,
cost, about $2.50 for syringe Jay CGVRZ |
+1 Planecrazy
I do the same. Cheap pump oil can and short piece of tubing. Push fluid in from caliper until it runs out the reservoir. Much easier if the cap is off;)
|
I also do same as planecrazy. Remember, there will be times to bleed one side or the other and having that dedicated pump can ready to go is handy.

I wrote an article on KitPlanes about making a pump similar to the one shown above. All the parts came from a hardware store and it cost approx $20. A few pumps to pressurize the tank and no more work. It was around nov/dec 2014. Everyone around the airport comes and borrows it. They just add fluid to the container.

I use an RC model electric fuel pump to both suck out the old fluid and pump in the new. To fill or extract connect the pump to the caliper.
I have a modified brake reservoir cap with a hose that I place in an empty water bottle. When filling I run the pump until brake fluid exits the reservoir. This helps ensure that any air bubbles are removed. Takes about a minute a side. (I have a reservoir attached to each master cylinder). |
Thanks to All
Thanks to all for the enlightening. I think I will try the oil can method for starters. I think Harbor freight might have the MITY VACUUM also if the oil can does not work....

Just make sure you have the right brake connected to the right brake and the left brake connected to the left brake. Otherwise you can spend a whole day of cursing, wondering why the @#$% brakes won't bleed.
Ask me how I know......... :o |
