Back Brakes

[barnett468]

hello;


i would do everything mentioned above with the following addition.

remove the caliper and place it on the ground with the brake line bolt facing straight up. if you do not do this you will most likely have air.

open bleeder and let it gravity bleed for around 1 minute with the clear hose as el camexican suggested. if you decide to imbibe during this process as he suggested as an option, please drink somethin manly like Jack and not some fufu Rum cr_p. I can't think of anything more fufu than suckin back a bottle of somethin that has a picture of a fufu lookin pirate on the label like the one below.



don't let the master cylinder reservoir or the bottle if Jack run dry.

reinstall caliper

put the e brake on.

let it sit for 30 minutes

push brake pedal down and do not let up ever until you are done.

crack the bolt holding the hose to the master cylinder slightly and let some oil weep out for a second. this eliminates any air bubbles that are trapped there.

finish you're Jack and you're done.


PS - Do not use that spongy DOT 5 cr_p. Use DOT 3 or 4 only.

There's no need to remove a 200x caliper just to bleed it.
Its a simple system and an easy brake to bleed under normal circumstances. If it wont firm up enough while mounted theres something else to worry about. (that's what she...... oh nevermind)

Oh ya, I guess I'm supposed to say "in my opinion" so no one can tell me I'm wrong

I'm gonna assume he's got er by now. Either that or he's good and drunk

By the way, its ZERK. not zert. And it wasn't a typo lol.....

Hello;

Actually, the way the caliper is designed and mounted on some bikes, it is possible for it to trap air unless it is rotated slightly. One can see this if they remove the piston and look at it. The bleeder hole in the piston area must be at the highest point with the caliper installed.

It will still work with a small amount of air in it, so you might think it is working perfectly, however, it will obviously work better if there is no air at all and un-mounting it and placing the bolt straight up helps insure this. It also removes the slight loop in the brake line.

I started hanging the entire KX and KXT front and rear assys on the wall with the master on top for a few hours to get all the bubbles out and I can assure you, if there is just a small bubble it will affect the performance and feel of the brakes.

Contrary to what you might have seen on TV, or heard on the radio, the longer it stays firm the better. There is no need to call a doctor or a mechanic if your brakes remain firm longer than 4 hours. And no...putting little blue pills in the fluid reservoir will not make them any...uh...BETTER...yeah, that word sounds safe enough.

Hey Mr engineer. This ain't a KX.

It doesn't need dismounted to be bled. You two goons are worried about teeny bubbles and his brake isn't "grabbing" at all.

Hey, good to see you guys agree on something, even if its tiny bubbles in a hose.......

Hey Mr engineer. This ain't a KX.

Thank GOD!

It doesn't need dismounted to be bled.

Yes it does.

You two goons...

Hey...just who are you callin a goon?

are worried about teeny bubbles

No...we're worried about "Tiny Bubbles", not "Teeny Bubbles" Einstein.

and his brake isn't "grabbing" at all.

Yes, but if he bleeds it as we suggested, it will no longer have "TINY' bubbles as it fails to "grab".

Hey, good to see you guys agree on something,

Yes...you don't know a THING about bubbles.

even if its tiny bubbles in a hose.......

I might get that looked at.


OMG Barn...I surrender, please stop!

I know enough to know that its fine to bleed a 200x brake without taking it off the bike. If you aren't qualified to make it work then I guess you might start blaming tiny bubbles for your lack of skill or experience with this particular model.

In my opinion
