does it really matter if the inner bleed valve or the outer bleed valve is opened first when flushing the fluid in the brake system. from the copy of the manual i have it does not specifically say which one shouyld be done first. i just did my brakes starting with the outer then the inner valve and all seem good. comments

 

I was instructed inside then outside last. Don t know how much it matters???

Inside-Outside. Clear the air in the middle of the system, then push bubble free air to the rest of the system. Wastes less fluid this way too.

It still works the other way around, but there is a small chance a tiny amount of air gets trapped in the middle of the system. When swapping the entire caliper I do outside-inside-outside. The first outside bleed is a quick one just to get fluid into the majority of the internal cambers. Then follow up with the traditional inside-outside bleed order.

 

Hmmm, it does say inner bleed valve first in our diy....

 

The more important piece is to work on the caliper farthest away from the master cylinder first. RR, LR, RF, LF in that order for LHD vehicles.


Within a caliper the inside-outside method is preferred. This way you "finish" at that corner farthest away from the master cylinder.

 

But dont we want to finish at the valve nearest the ms with logic saying we start at the farthest and finish at the nearest?

 

Tap the caliper with soft faced hammer to free up the small bubbles that cling to the inside while bleeding..tip from PFC expert at Club seminar.
