Questionhello
well, i have my brake caliper taken apart and as best as i can, cleaned. i picked up a new piston seal and yet i'm still not able to get the piston past the seal and back into place. how difficult should the piston's instalation be. i'm leary of trying to force it into place and yet it would seem it should be somewhat tight as to have a seal.
also, i have a new found electrical issue. taking a break from my brake problem, i decided to try to install a fresh battery and fire the beast up...to give myself hope. anyway, with the positive side connected and as i was connecting the negative side the bike tried to start even though the key was in my pocket and the switch was in the off position. any ideas?
AnswerLaurel, first you have to clean the groove out in the caliper REAL well. Make sure that there is no corrosion in the groove. An angled scribe-tipped tool or something similar is needed to clean the seal groove. Once that is done, dip the seal in brake fluid and put a little on the piston sides. Don't assemble it dry. A little thumb pressure should pop it firmly into place. Remember the rounded edge of the piston goes into the caliper. I am assuming that the bleed screw is open and/or the caliper is still disconnected from the brake line, so there is no backpressure to fight against.
Sounds like your starter solenoid contacts are stuck together or there is something lit up due to improper wiring. The solenoid is the direct connection to the starter motor from the battery. Check to see if the wires look modified/burnt around the battery box area. Normally the starter button puts a ground on the solenoid primary windings, which energizes the field in the solenoid and brings the contacts together to energize the starter motor.
The starter primary hot wire gets energized from the ignition switch and should only be hot when it is turned ON.
Check the wiring diagram links I sent before to see the wiring of the starter system.
