new Raleigh record 1970s. need some advice on upgrading brakes

ok so been doing some reading and am in need of some clarification and some major advice. first, the front brake was broken so i took it off and am going to replace it. while the tires are fine i do plan on replacing them as they are 30 years old. can i replace them with modern brake system? i have found a brakes just like that on ebay, but if i get them i would want to switch out the brake pads so i want to just upgrade the brakes. but im thinking about getting new wheels, should i get new wheels first since that might change the brakes i need, if i read correctly. am a little confused about that. the brakes are center pulled, if that is the correct name for them.
also is there like a book i can read or something i can read to learn about bike repairs, on older bikes espically, or any websites you suggest. thank you so much
the first brakes are what is on it the second one is the type of one i want to put on it, so you can have a better idea of what the heck i was trying to say haha.

Modern dual-pivot calipers are unlikely to be any more effective than your original centerpull calipers (dual-pivot calipers are more powerful than old-school sidepull calipers, but whether this is enough to justify replacement is a personal choice), so I'd just replace the pads. If your rims are steel, that could be the limiting factor in braking effectiveness, particularly in wet conditions. Changing to aluminum rims is a significantly more involved and expensive undertaking than replacing the brake pads, though.

If you do decide to replace the calipers, the significant things to keep in mind are "reach" -- the range of adjustment as measured from the mounting bolt to the top and bottom of the slot where the pads are installed, and whether or not your frame can accept modern, recessed bolt calipers. If the reach of your replacement caliper is approximately the same as the original, it ought to work. If your frame is intended for nutted, as opposed to recessed, mounting bolts, you can either find a modern caliper with nutted mounting hardware (there are some from e.g. Tektro) or drill the back of the fork for the recessed hardware and use another front caliper with a nut as your rear caliper (front calipers have longer bolts than rears, and will extend far enough past the rear brake bridge to allow a nut to be used).

"also is there like a book i can read or something i can read to learn about bike repairs, "

https://www.parktool.com/blog/repair-help has good tutorials on various repairs and adjustments. Just click on the part of the bike of interest and follow the guide.
https://sheldonbrown.com/ is more detailed and specific but has a wealth of information about older bike models and systems.

Also, using proper punctuation, grammar and capitalization will help the folks from whom you are seeking free advice understand your questions better and also help your credibility, both on this forum and in general.

A mid 70's Raleigh Record would have had wheels with steel rims. Upgrading your brakes won't help you if the rims get wet. Even when dry, braking may not be all that great. Those old Weinmann center pull brakes were pretty good, especially if you upgraded the brake pads. Want better braking? Look into finding a set of 27" replacement wheels with alloy rims, you can still find them out there and you can also still find tires to fit. If you move to 700c wheels make sure that you can adjust the brake pads at least 4mm downwards to line up with the new rims. New wheels with your old brakes will be a huge upgrade

I would get a replacement front brake just like the original one. Those old center pulls work well. You should be able to find a used one in a bike coop for very little money. Try to find a bike coop in your area, it will be very useful.

The biggest difference you can easily make will be new brake pads. Get Kool Stop pads in the salmon color.

The steel rims will be fine for braking in dry weather, but bad in the rain. The salmon Kool Stops will help a little. But you'll have to be careful in the wet.

I believe, the salmon Kool Stop Continental is the model, he's looking for, right?

Also what was broken about the brake you took off? The straddle cable? That's a cheap and easy fix. You're looking at probably less than $15 for a straddle and a pair of Kool Stop Continentals. Of course, you're still going to want to upgrade to an alloy rim (if you go to check out someone's old ones, take a magnet and make sure it doesn't stick), to get the best stopping.

Probably going to want to replace the rear pads as well as those suckers are going to be rock hard and not help your stopping problem any.
