Strength of Mortar
Typically, mortar has less compression strength than the bricks it holds, at perhaps 50% to 70%. If we assume brick strength of 5Mpa, then 50% of that is 2.5Mpa for the mortar.
Mortar vs Tapcon's "Lightweight Block"
"Lightweight block" is listed by Tapcon to hold 620lbs shear, and it is rated at 3.6Mpa (3.6N/mm^2) compression strength.
Your 4-screw rod
Your 100lb load will distribute over the 4 screws you plan, plus any friction between bracket and wall. Assuming zero friction as a most conservative estimate, this leaves 25lbs shear force per screw, or a mere 5% of the maximum static load capable.
Static or dynamic load?
Your failure mode will not be the screw, but the unknown compression strength of the mortar at the specific but random locality where the screw penetrates it. Relying on several screws, 4 in your case, each singly capable of handling the maximum load, is prudent and provides plenty of margin.
Nylon plug
