Steve Jelf- So KS Posted February 3, 2019 Report Share Posted February 3, 2019 ...without removing it from the truck. Several years ago after a leaking wheel cylinder drained the master cylinder dry, I refilled it and used air pressure from a shop vac to get fluid back into the works so I could bleed the brakes. Now another leaking wheel cylinder has run it dry again. But this time the shop vac isn't helping. I've filled the reservoir and applied the pressure trying to shove the fluid in, but the cylinder isn't pumping. I've tried several times and it's just not working. Any suggestions?

allbizz49 Posted February 3, 2019 Report Share Posted February 3, 2019 Try gravity bleeding it. I've never had to do it on a car or truck but it worked for me on a clutch slave on my Ducati. Top it off,crack the bleeder and let it sit. Just make sure to not let it run dry. Quote Link to comment Share on other sites More sharing options...
kencombs Posted February 3, 2019 Report Share Posted February 3, 2019 A vacuum bleeder from each wheel bleed port works well. Mity Vac is one brand. Lots of cheaper versions. Quote Link to comment Share on other sites More sharing options...
