Picked up a 1983 JD Model 420 this spring to put a grapple on. It runs very well but the brakes are almost non-existent. So a few questions:
1) How strong are the brakes on a 420 when they are working good?
2) I don't have a repair manual yet (on order), so are there any tricks to making a brake job easier?
3) Are there any recommendations as far as what should be replaced while I'm in there?
