Have anybody used this 1-way check valve brake bleeder when doing a brake fluid flush on their Fit? I am planning on doing a brake flush on my car which is way overdue with 100k miles and never been flushed.

Also what hose inside diameter do i need to fit in the bleeder valve?
Thanks.

 

I had to read the buyer reviews to figure out what it did.

Seems you put it on the bleeder valve at the wheel and just pump the brakes. The valve allows brake fluid to flow one way when the pedal is pressed, and avoids sucking air in when released.

I'd be concerned about air leaking around the plastic tubing and getting in the lines. Better to use two people or a just yourself and a vacuum pump to suck the fluid from the bleeder.

Mity vac makes such a device.
It's ok if you have no friends. Having used this I'd opt for a 2nd person and pumping the brake instead.

 

I used this one way check valve to bleed my brakes but during the process, there are some leaks on the bleeder nipple where I connected the hose.
Any suggestions on how to prevent brake fluid from leaking? The hose ID is 3/16.

Thanks.

 

In my opinion, you still need two people to do the job, because even with a one-way valve and a decent fitting tube on the bleeder screw, I usually notice some air gets sucked back into the caliper from the threads, or between the bleeder screw and hose.

The best way to avoid it is to tighten the bleeder screw "in the middle of the stroke" while someone is depressing the brake pedal, specifically once you visually verify that all air is expelled.
