    Hehe nah just unbolt the master cylinder and put it in a plastic bag and go in another vehicle.

    If you want to ride the bike with no rear brakes, remove the whole rear brake, caliper and all. Think ahead though - you will be surprised how much you rely on your rear brake.

    Really? I wouldn't think some people need to rely on their rear brake at all, some never use it!

    Now riding a bike with no front brake, that's tricky, had to do it the other day haha bloody hard stopping on a downhill and needing to put left foot down with only the rear brake!

    Most people have got it right on here,about stripping the master cylinder and brake caliper, BUT dont just grease around the boots, put rubber grease [about $ 8 a tube] over the pistons,seals etc [internal on the caliper and master cylinder]..., ive done heaps of brakes in my time and yes they do need internal lubrcation.......

    For real? I figured the grease would stuff up something in the hydraulics. Both these cylinders I did had perfect rubber in them - looked like they were perfectly well lubed. It was just the ferrous metal parts under the boot (outside the hydraulic internals) looked like it had never had any protection, so after cleaning it I filled it full of coppercoat.

    It feels horrible braking the wet with only the front, but I'm referring more to little things, like slow speed stuff, and hill starts. It is usually taken as read the rear brake can be used, until suddenly it cannot. There is usually a confused moment, followed by an oh shit moment, followed by a crunch.

    Return hole in master cylinder will be blocked . remove and strip master cylinde and clean with brake clean and air or if needed a little piece of wire . rubber grease seals before reassembly

    I have a similar problem at present with my Hyo.........except on all 3 calipers

    After 25,000km my pads needed replacing. Went to mechanic got them all changed. 5,000km later they were grinding again. Go back to mechanic and the pad on the piston side of the caliper on all 3 calipers was completely gone.

    So replaced the "destroyed" pads and off I went. So brakes sound as though they are sticking, all 3. Last night after 1,000km of this I pulled the front calipers off to check the brakes again. Pulled off the front left and noticed a bit of wear.

    Now for the cracker..........pulled off the front right and there was no wear. Looking at the non-piston side pad I noticed a circular scratching on the back of the pad, then looked at the caliper and noticed about 1mm has been shaved off the caliper..........

    When the caliper had been put back on the bike the pads the disk had gone up behind the pad and not in between the two pads. So for the last 1,000km one caliper has been braking using the caliper housing and the back of a brake pad!!!!!!!!!!!

    To say the least I'm f'n furious right now.

    That's fantastic!
    What did your mechanic have to say for himself? Much damage to the disk/caliper?

    Woops. Thats a bit embarrassing. I didn't think brakes could be assembled that "wrong".

    ... makes note to self.

    I didn't think so either but tested it and it can easily be done.

    Will post some photo's a bit later on for your enjoyment

    LOL thats awesome..

    Did a bike shop do that? It looks like you've been carrying your 200kg momma on it.

    Oh well, its cheap enough to fix.. The hard part will be gettting the bolts out of the fucked discs.

    I just took mine to the mechs, piston inside the master cylinder was poked, pitted and slightly corroded.
    Had to order a new master cylinder from Richard Hyosong, will install when it arrives in a couple a days...
