What causes air loss in the primary reservoir when brake is held down on a air brake system?
You'll have an initial loss of pressure in the primary tank, simply because that air is being used to charge the service chambers of the brake cans... a transmission line to the foot valve (pedal or treadle valve, depending on the mounting) transmits air from the foot valve to a relay valve... that air actuates a plunger which opens up the lines to the brake chambers with air already charged into a feeder line. If it continues, then you have an leak either in the service chamber of one or more brake chambers, or a leak in the air line somewhere in the primary air system.
How do you clear a blocked brake line in 1993 Chevrolet Suburban 2WD?

A 1984 Mazda B 2000 truck has two brake lines on the rear drivers side. I am accustomed to a vehicile having bleeders on all four brakes. How do you bleed the brakes on this truck?
This is just a secondary brake line in case something would happen to your primary line. Instead of bleeding the brakes with the bleeder valve, chock the wheels and slightly unscrew the fitting on the brake itself while a friend gently pumps the air out of the brakes. Make sure between each brake you top off your brake fluid. the bleeder is on the passenger side of the truck. use this to bleed both of the wheel cylinders. i have had to find out the hard way on my 1984 Mazda b-2000
