First of all, sorry if this has been brought up before but I didn't even know how I could search for this specific topic. If you want to send me a link to another post, that's fine.
I was riding a few days ago with a friend who just bought a new bike. He has never had hydros before. This was the second ride on this bike and there was no evidence of fade possibly due to air in the line.
Anyway, we're riding along and only climbing at this point in the ride so he had not been using the brakes to this point. Suddenly, his front brake starts squealing once per rotation. First thing I started thinking is that he might have a slight warp in his rotor but if we try to realign the caliper, maybe that will get us through the ride.
We stop to take a look and it's actually worse than that. I wanted to give the wheel a spin and watch the rotor move through the caliper but this resulted in less than one full rotation. The pads had really squeezed in and were pressing on the rotor from both sides. Remember, we were climbing up to that point so there was virtually no use of the brakes. There was a very slight bend in the rotor, less than 1mm deviation so nothing serious based on my previous experience.
We pulled the front wheel out and forced the pads out a bit to open up the gap, put the wheel back in and gave the brake lever a couple squeezes. Nothing. Lever went right to the handle bar. Repeated squeezing did not result in any improvement.
Does anyone have any comments on what might have happened. Any time that I've done this with my Juicy brakes, they've reset back to normal with only a couple pulls of the lever. Isn't that what they should do?
