bleeding brakes

[MrWasabi]

Ive got an air bubble in my master cylinder, and ive noticed that my brakes are a bit spongy lately...
so im going to bleed the little sucker out of there...
now, Ive bled brakes on cars before, countless amount of times, so i know the concept behind it.

However reading through a few websites and the owners manual, it talk about having a kit to do the bleeding on the front brakes.
I need a clear tube and a container and some other rubbery contraptions.

Now what im used to having as part of my "Kit" is, a spanner and a container. Loosen the bleeding nipple at the caliper and pump till air stops coming out.
when the air stops hold the brake down and tighten the nipple again. bingo! you got yourself an air free brake system again!

now why the hell do i need all these ridiculous things for the bike? are they not the same concept?

gettin a 1man bleed kit with the little bottle is a good idea, i use one, veeeery helpful.

before ya try that if its in your master cylinder it will take a while to get out try cable tying the front brake on and leave it overnight, make shore you have fluid in the header, and come back in the morning spueeze the line between the master cylinder and header and watch the bubbles then remove cable tie and you have air free brakes

the system i use is pump brakes hard then with pressure still on the lever open nipple and expell fluid, close nipple, pump brakes again till hard then open nipple and repeat till fluid is clean and free of air bubbles

or go to super cheap and buy a one man tool i think there only a couple a bucks i used to have one but lost it and never go around to replacing it lolz should but makes it so much easier having the right tools

I tried all the above when bleeding the 10 and I found what Tim has suggested works awesome. They are about $15 bucks and worth having in your tool kit.

P.S. tasting RBF600 brake fluid causes vomiting

Now if you've got the feel, you can open the nipple a little so that when you pump the lever fluid goes out but doesn't suck back in. If you've got a hose with a little plastic bung in the end (you can make one yourself pretty easily) to restrict the flow out you can pretty easily keep pumping until the hose is full of fluid. Stop pumping and open the nipple up further and hey presto gravity does the rest and you'll have fluid seeping out the bottom without you pumping. Keep topping the reservoir up until your happy with it and close the nipple.

While we're on it. I was going to put RBF600 into mine on the weekend and the dude at the shop said it does nasty things to magnesium. He opened the label up on the back and there it was in Motuls own writing. Now I don't know whether the 10's master cylinder is magnesium (I'm tipping not) although it's the right colour so I didn't take the punt and used the Dot 5.1 stuff instead. The RBF 600 is apparently also a bad one for paint etc.

I bought myself a bleed kit at an auto shop for next to nothing, makes the job very neat and tidy, no need to stuff around with oversize pvc tubing and find break fluid spilling all over the place. (yes I've done that one). I bleed the brakes about 4 times a year just for the hell of it.
