Bleeding: Also proportional valve?

[bikemaniac]

Hi,

I need to bleed the entire brake system. Is it also necessary to bleed the proportional valve? It is not mentioned in the manual.

I dont believe it is necessary,Ive have never had to. Some people do it when they are at wits end but I cant recall anyone saying that it helped.

just start with the furthest wheel away from the master and work your way in, always works good for me and i've bled my brake quite a few times before I decided to change out every line to SS!

yeah as above I wouldnt worry about it mate, I've just put my truck back together after a 2 year body off ground up rebuild and replaced most of the brake lines and bled the system up from dry pretty easily without worrying about bleeding the proportioning valve

If you have a good master cyl,it will easily push all the air out of the lines.

I bled the proportioning valve when I bled the rest of the system a few weeks ago. I think its worth doing as quite a bit of debris came out with the first few pumps which could end up damaging something otherwise.

I just bled the system in order of distance from the master cylinder: rear right, rear left, proportioning valve, front right, front left on my truck which is RHD (if you are looking at the truck from the front).

x2 - slightly diff. for a RHD truck....
