You will not regret upgrading to discs. Not sure about your LC, but my 72' did not have self adjusting/self tightening drum brakes. On top of that each wheel had not 1, but 2 wheel cylinders. Every time after off roading in mud the shoes would wear down and I'd have to adjust them back out with a brake spoon. Often taking off each wheel as the adjusters had rusted frozen. I despise the combination of brake dust and brake fluid to this day......go out drive and brake to see if it pulled left or right and readjust. Perhaps my LC was missing some parts , but that's how it was............i knew the brakes needed work. But when i changed my wheels i didnt realize how much. Pricing an overhaul for all way around each drum brake front and rear with new drums was going to cost me about 800.00 so i elected to just upgrade to disc brakes. Its a little more expensive but over time it will be better. Now how much modification has to be done? Is this going to be a pain in the ass? And i know i should of probably done this before hand.
