I replaced my power booster and master cylinder on my 89 Ranger and I cant get any break fluid to my rear breaks, non not a drop. I've tried gravity bleeding and vacuum bleeding and the old pump and hold method. Front brakes....no problem. my last method is with a home made power bleeder. I have everything I need for that method except an adaptor for the main brake fluid reservoir cap. I hate to possibly destroy the only one i have by drilling a hole in it for an air hose fitting, but I've reached the end of my patients with a 15 minute brake bleeding job that is on its 3rd day! I think my problem stems from improper bench bleeding the new Maser cylinder. Evedently I bled the front chamber properly but not the chamber for the rear brakes. I want to know if power bleeding would correct the mistake and force the trapped air all the way out of the lines. It would have to right?
I installed a new break power booster and master cylinder on my 89 ranger. Now i'm not getting any fluid to my rear breaks only the front breaks work. Could it be because I didn.t properly bench bleed the master cylinder? If so I can fix that without removing it?
