What is the correct approach to changing the front pads on a 1973 350F? Is it to split the caliper by removing the two main bolts or is it done by removing the rotor guard, the tension bolt with spring, the two fender bolts and the hard line and then dropping the wheel? Please forgive my ignorance. Recently purchased bike with fully rebuilt caliper and new pads. Test ride front brakes squealing. Owner applied the proper goo on the pads prior to delivery. Quiet for two rides and now squealing again...Plan to remove the pads, inspect and identify source of squeal or replace with softer pads and goo accordingly. Any guidance, suggestions, or even ridiculing at this point, would be greatly appreciated.
