So, I got @ 07 low rider, 18Kmiles on her. Lately, I have to press really hard on my rear brake pedal to slow down, I can't even stop with it. I have bled the rear system, no difference. New fluid...The pads are real good yet. The pedal isn't spongy at all. The pedal only depresses a little bit, like it's supposed to. I haven't done any rear work to have caused it. Any ideas out there? I really don't want to bring it to my local wrench.

 

That's because you are supposed to use the FRONT BRAKE with it.

 

Did you adjust the push rod that goes into the rear master cylinder? If it doesn't have a lot of pedal travel then I would look at maybe a frozen caliper and the piston is sticking. My bike will stop with the rear brake no issue.

 

+1 on the caliper, check the pads for freedom of movement.

 

I haven't adjusted the push rod yet. Should I have to do that, even tho I only got 18 K miles on her. I'm ay a friends place right now, don't have access to tools to take the caliper off to check for a frozen pad. Does just 1 pad move? I don't think that the pad is frozen against the rotor, because the bike does move! I'd like to get the rear wheel off the ground to make sure it revolves smoothly, but, like I said, I don't have access to anything that would raise her. I know I'm not supposed to hit the brake if I take the caliper off, but that would show me if the caliper is frozen. I guess I'll have to put a screwdriver between the pads to get them back into position to go back on the rotor.
I really hate to take a 4 hr trip back home today, but I'll just have to rely on luck
