Spongy brakes on 09 Ninja 250

[Dizzi]

Ok so have done 3,000 km on the Ninja, and don't really think that should warrant spongy brakes, but maybe it does. Question would it be worth bleeding the brakes and putting in new brake fluid.

Being a newb yeah I may use the brakes a lil more but I don't grab them going through corners or anything like that on the odd occassion I set up before a corner using them but generally use the gears and have used the gears a fair amount to try and slow down when approaching lights or other stopping situations unless have to do an emergency brake but yeah just in the last week or so the brakes have felt not as firm as they did to begin with, any ideas or is it possible I am using the brakes a lil more than normal, or is it just general wear and tear.

They shouldn't be spongy Diz. If you don't get it sorted before the weekend feel free to bring it over for a look-see.

[Dizzi]

Thanks mattie, we need to drop the key rings off to you so maybe if your around tonight can drop them off and bring the bike, hey you finally get to test ride hulk junior. Whatever suits you, tonight, tomorrow night, we home both nights, we can bring pizza and wine.

hrmmm i never noticed this on mine dizzi, maybe i could test ride it for you

but seriously i never noticed "spongy" brakes, even at the track, they faded, but never felt spongy and that was with a lot more abuse than you are giving them...

maybe give em a bleed (i assume this is something dave3 would look at), check the calipers and maybe see if u prefer the feel of a different brake pad

Maybe the dial for the sensitivity got turned. A couple of times i noticed that on my bike, the brakes felt different, not sure if someone changed it during the service but i never did

I dont even know what spongy is, can someone clarify this with me.

[Dizzi]

Yeah man I got my bike back from service and I think it has been pretty much since then, problem is I can't really excatly remember. They dam well adjusted my clutch to to far out but the boys fixed that for me, man seriously if it aint broke then why fix it, grrrrrrrrrrrr. Big bro Dave to the rescue sanks Dave and Cath for lending your hubbi out. You guys need anything that I can do just hollar.

Dizzi, the bike is so new its probably just got some air in the lines as with most things new they arent always 100% perfect out of the box. Personally Id have the dealers service guys look at it under warranty. Dave#3 is just too handy though to say No too and he generally knows what hes doing

[Blurr]

Dave#3 is just too handy though to say No too and he generally knows what hes doing

but be warned he is very talented and inventive at destroying things as well!!!

Yeah the problem is they were perfect till I got it serviced, I'm happy for Dave to have a look at it, I trust him a hell of a lot more than I trust the mechanic who did the service.

[fireyrob]

Yeah the problem is they were perfect till I got it serviced

Sounds like they just werent bleed properly then!

[Dizzi]

Yeah they didn't even bleed them we just checked the service report and book what does that say, anyway all good would rather Dave have a look.

Not the only one dizzi who had their clutch lever wound out too far did bikebiz do yours?

Ninja 250r dont have the dial just the ol' school set up, of lever and master cylinder.
spongy means more play in the lever of the brake and isnt really a firm feel in the lines if that helps

[Wattie]

are we expecting too much from the 250R??

[ijuschill]

Bike is all better now. It had a few little air bubbles in the line which we bled last night and today Dizzi said they were heaps better.



Thanks Dave#3 & Cath for use of garage

[Cath]

I had a few air bubbles last night too...

Luckily, it wasn't bad quality booze and no hangover at all
