do I need one of these to bleed brakes properly?
I just rebuilt my Combination valve after the brake light came on. The valve was pretty nasty. I also replaced the Bendix brake booster and master cylinder since everything was apart.
Some discussion on the web talk about keeping the piston in the CV "centered" while attempting the brake bleed, to prevent the piston from ending up jammed to one side because of fluid pushing it off center. Never used this tool before.
I have a 73 XR7 with stock brakes disk/drum.
MC Bled w/o over-forcing the piston to the rear.
wheel cylinder/caliper bleeder screws greased to prevent air entering the line.
Tried Motive, One man check valve, and two man bleed technique. Very little fluid coming from rear brake
So far I have tried several methods to get fluid at the rear brakes with not much luck. A gurgling at the rear of the master cylinder told me I might have blown a seal in the MC while bench bleeding. I rebuilt the MC and want good advice before trying again.
Do I need the centering tool? Is there a sure way to bleed an opened system?
