There is special paint made just for this purpose. You can purchase it at most auto parts stores.
a brake caliper tool (really)
I have a 1973 Harley Davidson Elctraglide FLH that has the Banana-style front caliper (OEM# 44105-72) and a rear drum brake...so yes, early 1973 Harleys had a rear drum brake. What else do you need to know?
It's either a rotor (disc brake) or drum (Drum brake) either way you have to remove the wheel for both, for drum it takes a firm rap with a dead blow around the side of the drum and then should pull off. For Disc Brakes you remove the caliper and pads the the same goes for the rotor gentle tapping on the back side and it should come free. The rotor is bolted to the inside of th e wheel hub on a 3500. You need to remove the brake caliper, axle shaft, and wheel hub.
Replace the caliper and bleed the brake system.
For great results, you should always use a paint specific to the application. There are several brands that manufacture paint specifically for brake calipers, that are resistant to the high heat and the affects of brake fluid. They are available at most automotive parts stores, in a variety of colors and application methods.
rubber section of brake line to caliper clogged and in need of replacement
depending on the year you need to take the caliper of and it should slide out {the parking brake is under the rotor like drum brakes } you may need to tap the center hub to free up the rust but it should pull out then youll be able to check the parking brake shoes {like drum brakes underneath}
you need to check to see if your caliper is hagiong up It is more likely to be a rear drum brake problem than a front caliper problem. Make sure your shoes are not oil soaked or way out of adjustment.
Yes you will definitely need to bleed your brake system.
unbolt caliper, compress piston in caliper with c clamp and remove /install new shoes... may need to remove some brake fluid from resovior because of new pad thickness--use towel and don't spill on paint!....
Hose?
Remove the wheel and use a 15mm socket to remove the brake caliper bolts. Set the caliper aside and replace the pads. You will need a C-Clamp to push the caliper piston back in to accommodate the new pads. You will need to remove some of the brake fluid from the master cylinder before you push the caliper piston in because the fluid level will rise. If you do not remove any fluid it will over flow and make a mess. BRAKE FLUID EATS PAINT. Reassemble and pump the brakes. Add fluid if needed.
