Replace rear brake cylinder lost all fluid now can't get fluid out of antilock module to rear brakes
IF you can’t get fluid to rear wheel cyl - push in on the rubber covered plunger on front of the brake *proportioning valve* and hold it there while a helper pumps brake pedal. IF unfamiliar with this procedure - seek *hands-on* assistance from qualified personnel. Good luck!
