July 12, 20102005 Road King, 59,000 miles. Today going to work noticed a lot of travel in the rear brake before it worked. Coming home from work it didn`t grab at all, try`d pumping it but still very little if any rear brake. Checked the resevoir, added some it was about 1/4 inch down from the edge when level. No signs of leaking. Bled the brake and went for a ride, still little to no brake. The master cylinder right? Or is there something else I should check? Pads have about 5,000 miles. Thanks for the help.

July 12, 2010If your pads are worn down very far, I do not care how much you bleed the brakes and put in fluid you will not have much brake on the rear. I had the same problem a couple of timess on the Roadking I had, as soon as I put new pads on the problem left, until then I thought I had air in the lines , which was not the case, It was the pads had worn down too much and the cylinders just would not close that far, and I would loose pedal or have to pump like hell before they would work.
I am no expert, but I suspect new pads will take care of what is ailing your brakes, they are not very hard to change either.
Not knowing how you ride 5,000 miles does not seem to be alot of miles for rear brakes though, My 2010 Roadglide has 13,310 miles on it and I have never put brakes on it yet and it stops great, but I use the front brakes alot more than the back ones.
July 13, 2010Change out that Master cylinder IF the wheel cylinder isnt leaking...dont even mess with a rebuild kit.
July 13, 2010Trip, my dealer doesn`t have either the kit or the whole master cylinder. I`ll have to order, quite a difference in price between the two. I have the repair manual.Should I still get the whole thing? And no it wasn`t leaking anywhere. Thanks
July 13, 2010Rebuilding those Masters is an incredible PITA...i highly recommend just replacing the whole unit...i think they run about 119$ ....i,m assuming you tried to bleed any air already??...the masters fail internally (blow by) ....

the (unanwered) question I would have is...what kind of milage (in the past) have you gotten between (pad changes). You mention 59K miles or so and only 5k on the current pads.
If you (hardly ever) use your front brakes, maybe you have worn down the rear rotor and as VT has suggested, new pads might make the difference again. If new pads do it, it means to me that your rear rotor is past the limit for (resurfacing).
July 13, 2010Ok I phucked up. The last pads on the rear were at 37,000 miles. The front pads were replaced 5,000 miles ago. The pads looked good but I`ll replace them now and see what happens. Thanks for the tip on the master cylinder Trip, I don`t have the patience for PITA projects.
I gotta keep better records I did the same thing with my wifes car last week. Took it in for tires and rear brakes because the fronts had just recently been done. Picked the car up and the mech says you need front brakes too. Checked my receipts and sure enough it was the rear brakes that had just been done.
July 13, 2010I would hange the pads, I`ll bet from my experience that ,the pads have worn down so far the calipers aren`t pushing them far enough to make them engage properly. I had an 03 Roadking and it had 65,000 on it when I traded it last summer, I was having brake problems aroun the same mileage you said you have.
But , I am a novice the experts here are Trip and Tattoo.
July 13, 2010Try new pads but leave that caliper alone.
July 14, 2010Hey Willy,
Let me know if you need a hand. You can bring it by my place and we can trouble shoot it.
