2000-2007 Roadking/Ultra/Big Twin 4 piston caliper brake service
Did some research and some repairs, and discovered an issue with Roadking, but only in the 2000-2005 range, and ONLY with dual caliper/rotor brakes. These are the 4 piston calipers.
The issue is after awhile, the brake lever for the front starts to feel muchy and grabs lower then it should, regardless of fluid conditon and how much you bleed.
Here's the solution:
Remove one caliper. You'll need to undo the brake line junction/union block to allow the caliper enough room to drop down and off, without removing the fender or tire.
Leave the pads in, on their pins.
Pump the brake lever.
Theres 4 pistons per caliper. You'll see one come out, and 3 of the 4 will stick.... nice huh?
Pump the lever until the 2 ouboard ones come out. They won't/can't come all the way out with the pads in. They'll also come out first, inherantly.
Spray clean them with brake clean. Tooth brush can be used but isn't needed most times. You'll see them become clean and silver.
Push them back in with a screwdriver.
Now...hold that pad back, and pump the lever again, forcing the INBOARD PADS/PISTONS out.
Push them back.
Remount caliper onto the rotor, and back onto the fork leg.
Do other side the same way.
After you did the other side, pump up the lever. Be amazed.....
I'm told this should be done as a service interval at about 5K. Pad material (aftermarket) may vary over OEM.
