RE: Front End Shakes
I do know that a warped disc or discs will cause the brake lever to pull all the way in when applied at first just like when you bleed your brakes, they will come to full prime after a few pulls. The warped disc or discs will cause the calibers to push the pistons back out. I doubt its your disc, try a wheel weight. A old worn cupping tire will do the same. Dunlops are the worst, although all tires will cup some not as bad as others.

RE: Front End Shakes
Yea the break lever doesnt pull all the way in it works completely normal it shakes more the harder I pull it in. Either way I am getting it checked out in the next few days when my schedule allows.

That sounds like a warped disc to me, I know that you will get a vibrating feeling in the steering wheel of a car when the rotors are warped which is genuinely cause by hot rotor and cold or cool water. Maybe when the bike went down the disc or rotor what ever you want to call it hit and got bent somehow. I don't really know either but it does sound like a warped rotor to me.

RE: Front End Shakes
The easiest way is put her up on stands ?
If you have none , but have a center stand ? you can just get someone to sit on the rear of the seat to lift the front end off the ground..
In either case , once the front wheel is in the air , turn it to lock on one side or the other.
Spin the wheel and check visually for run out (warp) in the discs..
"Hint" - get something that you can fix in position like a straight piece of metal or aluminium ect ...
set it up next to the disc and spin the wheel ...if the fixed object touched the disc in one place but not in another ...she has a warp in it ..
hope you can work out what I mean mate

Your more than welcome mate
Some things with bikes you have to take to shops to get done or checked , but it is amazing the work arounds that you can come up with over the years to save some cash..
glad it was a bit of a help
