Getting my 2000 Valk out of storage (ride in Florida in winter). Had it up on a jack for storage. Front wheel moved freely on the jack. After applying and releasing the front brake there was quite a bit of resistance when rolling the bike. I can hear a dragging sound from the front brake/rotor. I have no leaks at the caliper. The brake fluid was changed a couple years ago. Examined the master cylinder for the front brake and found that the rubber boot which surrounds the piston that depresses into the master cylinder when the brake lever is pulled has deteriorated. Cleaned and lubed areas around the lever. Last riding season I also have felt a "ratcheting" as the front brake is applied. That is, the lever moves to apply the front brake in steps as the lever is applied. It resists then releases to apply more braking as I squeeze on the brake lever.
Any ideas on this problem?

Others will have good experience, but I would try to determine if it is both calipers or one. If one caliper is not free and the other is braking I would suspect that caliper, also brake hoses can go bad inside and turn into a one way valve. If both calipers are braking then probably the master cylinder. Let us know.

Did you make sure the tiny hole(s) in the bottom of the reservoir are clear? I forget if there are 1 or 2 holes, but they have to be open to release any pressure that would build up while the lever is not pulled.

I would start with the calipers.

I agree. When I had some brake dragging, I rebuilt the calipers and the difference was like night to day. Not a hard or expensive job. |

Remove calipers one at a time. Push piston back. Re-install , pump up the brakes and do the other.
Sometimes from sitting , they will stick but do not need a re-build. If they stick after this , then re-build.
If you have problems or concern , then re-build. Safety First.

That is what I did and it worked. Sometimes they just get stuck.  |

Last riding season I also have felt a "ratcheting" as the front brake is applied. That is, the lever moves to apply the front brake in steps as the lever is applied. It resists then releases to apply more braking as I squeeze on the brake lever.
Any ideas on this problem?
Lube the point where the brake lever contacts the piston in the m/c.
Wouldn't hurt to lube the lever pivot also.

Also inspect the foot, the curved part of the handle that presses on the m/c rod, I had to sand mine with emory cloth to get rid of the ratcheting |

How badly are they dragging? A car with disc brakes will do this also if you jack it up, apply the brakes and then spin a free wheel you'll hear the pads dragging a little on the wheel, that part is normal. If it's worse than that then follow the advise listed above.
