Today after I stopped for gas on my Suzuki Bandit 600, the front brakes locked up. After driving home with this condition the calipers were smoking, only way I could get the motorcycle home. I need some advice on what would cause this problem and what to look out for? I also took off the calipers and the cylinders seemed to compress without difficulty. I also inspected the master cylinder and it seemed to be pumping fine. One thing I noticed was that the left front rotor seemed to be slightly warped, but that could be due to the brakes being locked and me riding it home. Also I have never had any prior brake problems and they were working correctly the day before.
you didnt even mention the people that break into houses to steal the pipes from the walls. Because copper is much harder to extract, aluminum you just get the bauxite, crush it and put it in water, viola
crud around the brake piston stops it releasing freely ,
aluminum is probably being replaced with plastic and composite materials in such things as airplane bodies and equipment housing. copper's main use is in wiring, and there is no replacement for it (yet)
You say you removed the calipers and the pistons compressed easily. That means the pistons aren't stuck, normally caused when moisture in the system corrodes the cylinder. That leaves the lines and master cylinder. Old brakes lines sometimes swell internally and won't let the fluid return to the master cylinder, keeping them applied. If your bike has dual discs up front, were both of them hot? If so, that rules out the two lower brake lines because the probability of two lines both failing at the same time is astronomical. However, it could be the line from the junction to the master cylinder that's failed or either if your bike has a single front brake. A swelled line will usually relieve the pressure if allowed to set over night. You leave ok but as soon as you apply the brakes real hard, it locks up. The master cylinder could be bad, but I don't really suspect that. The little return hole could be plugged, but with fluid pushing out the hole, it would be hard for a piece of crud to stay lodged in there. Bad seals on the master cylinder usually fails to pressure up the system, not depressure it. If the system were together, you could apply the brakes hard to stick them and thenstart loosening the banjo bolts at the different connections. For example with the brakes stuck, if loosening the bolt at the master cylinder makes no difference, then that rules it out. If you loosen the bolt where the single like connects to the junction block and the brakes still stick, then you go to the lower lines. If you loosed the bolt at the caliper and fluid squirts out and the brake releases, you know it's that lower line. If the brake stays locked, then it's the piston stuck in the cylinder.
