Installed Rizoma Rearsets... Brake Problem

[cakeman]

Hi, ive just installed the brake side rizoma rearset with out to much trouble.. the problem is that my rear brake has only approx 5mm of play in it now..... Im assuming the brakes need to be bleed? Also i need to lengthen the hose from the brake fluid resovouir to the master cylinder (hose was included in the rizoma rear sets)..... for full adjustmeants of the rearset the hose needs to be lengthed.....

ive never bleed brakes before and am a little frightened of fluids

Im assuming that i can connect a hose to the rear caliper nipple, crack the nut and drain ALL fluid in to a cup or something....

Once all fluid is drained, i can lengthen the hose from the fluid resvouir to the master cylinder.

Once that is done... im a little lost on the process on how to bleed/fill the resovouir up with brake fluid? ive looked around but cant find any definitive way of doing it with out getting brake bleeding kits etc......

Also, when the bike was serviced a month ago, fluids were done, so im assuming it will be fine to use the same brake fluid? (if not... is it Dot 4 i need?)

Any help would really be appreciated.

Thanks!

Lengthening the hose to the reservoir is simple

put a rag around the MC and then

you can just pinch the hose above the MC and pop off the reservoir and hose

or

to further limit the possibility of a mess

you can go to your local wallgreens/CVS and get a 20cc syringe and suck the fluid out of the cup/hose

then pop it off the MC and lengthen the hose as needed

then install new hose on to the reservoir

and

fill it back up from the hose pushing the air out through the reservoir makes bleeding quicker

just pinch the hose while installing it back on the MC to avoid spillage.


As far as Brake Fluid, the cap on the reservoir will tell you what type to use, you can mix DOT 3 and DOT 4 but you cannot mix DOT 5.1 with DOT 3 or 4

The reason, I do not know but I think it creates hellfire

DOT 5 is silicone and can not be mixed with DOT 3, 5, or 5.1 which are poly glycol based.

DOT 5 is silicone and can not be mixed with DOT 3, 5, or 5.1 which are poly glycol based.

I think Howie means DOT 3,4, and 5.1 are glycol based and Dot 5 is silly cone

thanks for the clarification

I forget if mixing the two different types melts the seals and hoses or if it just gums up the works

regardless it is bad

When silicone brake fluid hit the market they thought glycol brake fluid and silicone brake fluid are compatible.  Over time it was found they don't mix and if the brake fluid temperature rose above that of the glycol fluid the silicon fluid would...ummm...I guess you could say fry the fluid into a gel.  Though this may not be likely it is still potential disaster.
