Yes, sacrifice the pads, remove the char and fill in with epoxy, then mount the new, larger size and higher rating, bridge rectifier either there, or with some short heavy leads to the existing other pads or tracks. Larger surface bridge for cooling than a tiny 1A part, I use a 3A square type if possible, or a 5A SIL part if space is tight, using short sleeved leads to make the pinout. you can drill new holes for the leads if needed. Have done plenty of track repairs for loose pads (thank you for 1970's era boards with poor adhesion) for non cooked parts using care, and a drop of superglue after soldering in a new part, and a wire link for trace continuity, especially on military boards where a replacement board (if available at all, or if lead time was in the year range) was a six figure sum in dollars.
Some of them were 7 figure prices, and I had to order them, because there is not much you can do if the only part that has survived the toasting session inside the case is the milled aluminium chassis, 6 chassis mounted stud rectifiers, the plug used to connect to the mainframe, and one of the 3 1A Littlefuse solder in fuses on a separate board, that are supposed to prevent this from happening. Caused by a common fault, one of the other rectifier diodes went short circuit, and it carried on operating till a second died from overheating. Came ordinary parcel post......
