Welcome to the site and sorry you are having belt issues. Since your person suggests a "brake puck" issue, have to surmise this is the engine to transmission drive belt and not the mower drive belt.
If you are able, you can go under the machine with a good light, and look carefully at all the pulleys yourself. If the belt is off the mower, check to see that all pulleys are aligned with each other, that is, each one "points" to the next one in line. So that if the belt were on there, it would travel straight line from one pulley to the next.
Then, you will want to wiggle each pulley to see if any are loose or wobbly. Each should also turn smoothly without resistance or wobbling on its attachment shaft. Also, if any are attached to a movable arm, does that arm move in line with the pulley or is it worn and lets the pulley droop or wander outside of the belt's plane of travel.
Check for anything that might interfere with the belt's line of travel, a loose part etc. Be sure there are no sharp edges on the pulleys. Some ride the V part of the belt and are V shaped pulleys while others ride the flat back of the belt to keep tension on it, those being "flat" pulleys. Again, all should rotate freely and be in line with each other.
If all seems OK to you, try asking the guy to explain how the old part, the "brake puck" is breaking belts. I learned a long time ago, that if I don't clearly understand an explanation, to ask until it IS explained and clearly understood. Its your machine and your money.
Good luck and let us know how this goes.

Is this the deck belt or drive belt?
I went through deck belt problems last summer. Mine wouldn't break but would turn over in the pulley grooves. I replaced all my pulleys including c/s thinking they were worn causing the belt to be loose. I went through several belts before I figured out that the belt engagement cable was only moving about 1/2 inch. I replaced the $12 cable and it solved my belt problems.

Weeel Michelle,
Considering that he's been out 4 times and you still have the problem, perhaps I would surmise that "this guy" is a parts changer, and not a mechanic who can diagnose the problem.
That being said; if "this guy" said your pulleys and such are good, I'm afraid that I wouldn't rely on that assessment either.
Then there's the brake puck (what brake puck - the pedal brake or the mowing deck brake?) causing belts to break ... ?
That's one I've not heard of before
Unfortunately Michelle, it's difficult to diagnose your issue without actually physically looking at your mower, or perhaps some pics and further details.
One thing for sure though; you likely need to find another guy.
In any event - Welcome To MTF!!!
