first time post and problems with brakes
« on: May 24, 2015, 06:53:19 PM »
hi
first time post.
owner for the past 4 years of a 1985 k100rs.
love the bike.
just not this spring.
so a bit about me.
I live just outside Toronto Canada.
rode mini bikes, three wheelers and dirt bikes as a kid and teenager
left two wheels for a few years once i started to drive.
this motorcycle fell onto my lap (literally) a few years ago and so here i am.
anyway, i made a promise to myself that i would start doing my own repairs and maintenance this year.
oops wrong year.
this spring i lost the battery, which i replace without too much trouble.
one ride later and the back brake.  she ist kaputt.

i referred to the manual.
oh, perhaps i forgot to mention, when i look down at my hands, i see 10 thumbs.  I think i am supposed to see 2 plus fingers.
nope.  not these mitts.

anyway.
looks to be the master cylinder attached behind a metal bracket that holds the foot peg and the back brake pedal.
this metal bracket has 4 allen screws holding it onto the frame and extends back so that the saddle bags can also attach.
i checked underneath and it looks that from below the M/C is attached with two smaller allen screws and that the foot brake pedal attached with a nut. (front of the brake pedal is attached by one of the 4 larger allen screws mentioned earlier.
so that is where i stand.
Q:  how to remove the M/C.  remove the metal bracket first, last or not at all,
Q: how to remove the lines into this master cylinder. one line to the reservoir, the back out to the caliper on the disc brake, and the front is attached somehow to the brake pedal.
Q: do i repair the M/C with a kit or replace the entire MC with a new one?
Q has anyone ever done this repair on a 1985 k 100 that could give step by step instructions right from the start?
Q: am i crazy?
Once i replace or repair the M/C i will need to learn how to bleed the line.  baby steps.....

please help.

It is really not too hard, follow the directions in the manual. If I remember, you remove the luggage bracket, then unbolt the foot peg bracket, then you will have access to the master cylinder. The line to the brakes is bolted on, the line to the reservoir has a clamp and will slide off (I think). I just went ahead and replaced mine, but you can buy the rebuild kits too.
