what is best for my corolla93 most of the time city driving so lots of stops.
Use a double ferrule oil and gas compression fittingCut off the desired length and use the compression fitting to join the two pipes
There is a compression fitting made just for that purpose. Cut out the bad section and replace using a new piece and the compression couplings. No soldering needed Check with a plumbing suppy house, they speak the lingo.
turn water off to that section. cut pipe where the hole is (pipecutter) if its 1/2 copper get a 5/8 compression coupling. using 2 wrenchs tighten both sides. turn water back on check for leaks. your done.
Ceramic pads are good but pricey 93 corolla how much longer are you going to have it cheap pads should last 2 yrs
