I'm having trouble bleeding the brakes after the hydroboost conversion. I swapped the master cylinder and the hydroboost unit and pedal but now I'm having trouble bleeding the brakes. I tried to use the pressure method with a pump up sprayer but have nothing coming out of the bleed...What's holding me out? I'm not very familiar with the hydrolics of the brake system on this truck. I'm hoping I don't need that tech 2 to cycle the abs like some trucks use...any help?
