Flushing the brake fluid ?

Is this the correct product to fit the cap on our Master Cylinders ?

 

Motive Product 0107 for Asian cars.

Pretty darn sure it is, that’s the shape that my Motive cap is for the master cyl reservoir. I opted for the billet aluminum cap instead of their plastic version. One issue: the cap locks into place on the master cyl without too much hassle but it is EXTREMELY hard to unlock and pop off. I have no idea why. Sometimes I feel like I’m going to break the master cyl just trying to unlock and remove the cap.

Thanks, I placed the order for one. Been thinking about getting one for awhile.

 

Any tips on using it ?

directions were pretty straightforward. The main issue for me since I've never used one before was I assumed that the hose leading to the master cyl cap would be completely full of brake fluid once its under pressure. This is not the case, (I called them to be sure). You'll see fluid in the line but the line won't be completely full of fluid as it feeds the res.

That air in the line is what my concern was.

 

Seems the air just rises to the top as you release the pressure from the tank leaving no air in the system.

yup I called the Motive folks to to ensure I was reading the directions right and sure enough I was. So yup you're assumption is correct on air in the line.

Just scary when you think about air and the brake system.

 

Thanks,

For sure, essentially they told me that as long as your reservoir has has fluid in it and the canister is pressurized its forcing fluid thru the system, (and any air bubbles in your brake lines as well) even though the hose isn't "full" of fluid.

Yup, air stays at the top of the reservoir.
