gt250 front brake help

[Donut]

i just got my 2008 hyosung gt250r and hav now done 470k's and my brakes were find at the start but now they have started to squeak loudly and and verry spongey and uresposive.. is this from air in the brake lines or something else ?

Take it back to the dealer and explain your plight and politely request a brake bleed and replace the stock organics with scintered brake pads (offer to pay for the new pads of course).

The pad change makes a WORLD of difference to Hyosung brakes, and yes they should come with them in the first place, but they don't.

Cool thnx, are there any other improvements you can suggest to make the bike any better ?

[carbacca]

squeaking would be due to the pads not being bedded in properly and hence becoming glazed. its not dangerous just annoying

sintered pads make a hella lotta difference so i am told. i wouldnt know since i am still on the stock pads for the last 8000km. they are more than half gone now and i have bought two pairs of sintered pads which is now sitting under my desk. i think i will do the brake fluid at the same time when i change them out, since its coming up on two years now

400ks and still not bedded in.. thought they would of by now but i guess ill leave em for a bit. im doing the coro loop a few times this weekend so i see how they are after that

Braided brake lines make a huge difference to the amount of power, and on Hyosungs actually increase rather than decrease feel.

hmm seems like putting in braided lines would take a bit of effort :S spose as long as its worth it... whats the best tyres i noticed the std ones dont grip so well in the wet

[mogiman]

braided lines on my old gixxer made a big difference gave a bit more bite and its not a had job just got to bleed them right

where is the best place to get braided lines from? are they available in standard lenghts or are they all custom made lines? thansk heaps and would a new master cylinder improve teh feel further?

Oh and sorry for highjacking your thread Donut

[James Deuce]

Best thing to do is get your local dealer to source them. They'll be able to get the right ones for your bike as well as making sure they comply with the standards for brake fittings.

anyone else noticed a flat spot in 3rd? i was in 3rd gear at about 60k and went to dial it on and it just sat there for a bit before it started to accelerate :S

Stop being a Nana and cane that thing, they like it you know? My std pads didn't last 2000K's and that included the run-in! The scintered ones last less than 4000K's, that is with the single front disk tho.

Yes, that'll be a problem with the CDI unit. I'm surprised it's still a problem with the 2008's though.

I think the problem first appeared with the 2006's, and I heard they had fixed it with the 2007's but mine still has the problem.

Talk to your dealer about it. They should replace your CDI unit under warranty.

For what it's worth, I tend to stay in 2nd until around 65-70k as the power delivery is better (great for when the idiot in front of you does something stupid and you need to pull away from an impending crash). Plus, this way I don't end up in the flat spot much.

[Pancakes]

Yeah I agree, they smooth out lots above 8,000 RPM. Get way faster throttle resonse too compared to the next gear up.

1000 posts! Never thought it'd happen!

I replaced mine, but noticed the stock ones on my bike were sintered already... if you've glazed them over by too softer breaking you can remove them and roughen em up a bit. I agree with probably just taking it to the dealer however :
