'88 Southwind P30 master cylinder replacement

[atikovi]

I changed all 5 brake hoses and will replace the master cylinder since it's cheap and I might as well since I have to bleed everything anyway. Is there some trick to bench bleed this thing? I can only get fluid flowing in one chamber. I installed it like that and bled all the lines but the pedal goes pretty far down. Will have to take it off and try again. Not a fun job as you are doing this pretty much on your back.

The length of the master cylinder rod into the Hydro boost is critical.

Bleeding the lines is no problem. I'm using a Phoenix reverse fluid injector. It's the master cylinder that is a problem.

Can't really help but I just replaced all the brake lines in my little jeep wrangler and it took forever to bleed out the back ones. Motorhome is like 5 times longer. I could see it taking at least 15 min using the brake pedal to the floor and closing the bleeder method to get the air out of the first one in the rear.
