"Have you seen Junior's grades?"
2011 Roadster 16,000 miles. OK, so this is not the first time someone has posted this question. But I have not seen a good answer yet. I will start at I replaced the front & rear pads and bleed the front & rear brakes and added new brake fluid in October last fall. All was great, excellent brake feel front and rear no problems at all. I had not rode the bike for a few weeks and in May I took it out and there was absolutely no rear brake. Pump the heck out of it and get a spongy feel. Bled the rear again and get a perfect rear brake. Took it out yesterday and no rear brake again. I know this can be a master cylinder issue in a car but it in a car it happens very frequently, like you go a mile hit the brakes and get a very bad fade. In a car you can actually hold the brakes and feel the pedal go to the floor slowly. With this issue its fine all day after you get the brake feel back. Let it sit a few days or a week or so and nothing. Has anyone replaced the master and fixed the issue or has anyone rebuilt the rear caliper to cure the problem?
