That's what I would do. Fill in all the empty cracks and spaces with more mortar.Mortar !
I actually used that on a house I was selling.. The home inspectors that came agreed with me that it was awesome! Excellent results, it's an acrylic based caulk that is tinted so that as it ages (a day to a week) it turns to the normal mortar color. Quikrete (to me) is a company that makes excellent products. So.. go ahead and try and find a contractor lately that calls you back! Instead of wait to pay a lot.. This is a much quicker and easier fix.. It hardened and looks/feels just like mortar! Saved a lot of $$$ using this stuff! Plus the caulking tip is the standard width of the mortar lines! and it has a flap on the tip to smooth out the caulking.. I loved that stuff!!I would try this product:
Quikrete 10 oz. Mortar Repair Sealant 862009 - The Home Depot
Quikrete 10 oz. Mortar Repair Tube features an acrylic formula used for sealing joints in concrete, brick and block surfaces. The tube features a square applicator that provides a smooth seal for mortarwww.homedepot.com
I have a brick side walk that is about 28 years old. The joint mortar is starting to come out here and there. What do I use to fill these "holes"?
Is there some kind of caulking I could use? Do I need to mix up a concoction?
The only way to make it look really good would be to grind out as much mortar as you can and tuck point in new mortar so it's all consistent, just be aware this will not last another 28 years. When they first lay the brick they lay them in such a way they put pressure on the mortar in between the bricks which gives it some strength/durability. Also using a grinder with a masonry blade causes a lot of vibration which in turn could make it worse.I have a brick side walk that is about 28 years old.

hey Gebo.. Yep that mortal repair from Quikrete that I used on the house that I sold would work perfectly on your bricks. Except that was on the side of a brick house instead of a walkway, I don't see the difference in mortar application. Here I thought before it was a sidewalk that was concrete slabs not bricks, that's why I was hesitant but never mind that.. this is the same types of cracks in mortar that was on the house! exactly..Here are the pics. It's too hot to unload the U-HAUL at present.
Curious what’s the issue with caulking?Stay away from caulking. Only mortar. May not look the same exactly. Clear out everything loose first.
