Re: Need brake help, Can,t bleed fromt

Greg you have determined that you have flow to the valve, but what about flow from the valve?
Another "try this" is to see if you can attain any gravity flow from one line going to the front calipers. Disconnect the left front rubber brake line from the frame mounted metal connection and either let it gravity flow or pump the pedal. If you can get flow, establish fluid through the caliper and secure the bleeder valve before you start on the other side. If you are going to let gravity flow the fluid you will probably need to leave the master cylinder cover off. Catch 22 of doing this with conventional fluid is that brake fluid absorbs moisture so the fluid to the rear system will become contaminated and I would would remove all fluid from the brake master cylinder bleed new fluid into all calipers. With silicone fluid you don't have contamination of moisture from the atmoshpere. Good luck.

Re: Need brake help, Can,t bleed fromt

you are correct about gravity bleeding allowing moisture into the system. never leave a empty brake system open to the air as moisture will collect in it especially in cold damp weather in a unheated garage. since we had dry nitrogen for filling tires we would open all the bleeders and flush the system with dry nitrogen before filling it with brake fluid. anal i know but heading into the first turn at full speed is no time to find out the brakes do not work
