I have proven to myself that there is no air in my brake lines. I have a 1986 TRX200SX. I got it used. It is possible the MC and teh brake cylinders are not original to the quad. My cylinders were frozen up and I HEARD that I could use cylinders from a 2013 Recon. SO I bought them. They fit OK with some modification. The hand brake goes to the handlebar, and you can't lock up the front wheels even on gravel. So, I put two C-clamps directly on the wheel cylinders, just enough to hold them in. The hand brake is hard and only goes back an inch or so. So, we know the system is completely air free.
What I noticed is that my MC has an OT cast into it. ONE of my cylinders had OT cast into it as well. So, are the casting numbers and marks meaningful? Is it possible that my MC and cylinders are not matched and something about the new wheel cylinders requires more travel to activate the brakes, which my MC cannot achieve? Even with the adjusters locked up, there is still a ton of travel in the brake handle.
