Crap, broke me back brake.... I think - SV650.org

29-12-05, 03:03 PM

Pulled away with the disc lock on the back brake

now I never really went mad as I was turning the bike

. But I now have no back brake

I can only see a bit of a mark on the disc and it does not look bent.
So what you think

new brake disc

or could I have knocked the brake out some how

The best way to tell is to simply use it and see if it wobbles... A bent disc shouldn't cause total loss of braking though. I take it you've tried pumping the lever a few times? Does it feel normal apart from not braking?

Just feels very soft and i have to push my foot all the way down before i get anything, and yep tried my brake a feel times on the way home with no affect

has it possibly cut the pipe feeding the cylinder

if not perhaps a good bleed will bring it back

check carefully that it has not cracked any part of the caliper or the retaining arm.

Or maybe whacked a bleed nipple? Something like that. Your symptoms wouldn't be caused by a bent disc.

If any of the above are the case, you will find that your brake lever travel should be extended further than before without any resistance. But you would have probably noticed brake fluid on the ground.

Nope there is no fluid and I have to push all the way down to get any resistance at all

and even then it's not very much

Yes I have seen this problem before on television.

This chap had to push the brake all the way down to the ground to stop at all. It never went on to explain the cause but you could mail him.....

Sorry, couldn't help it

On a serious note, just take it straight to the garage. Theres no point risking your neck just to save a few quid.

Pingu...Very good mate!

Could the bang have made the pistons jam up in the caliper? They might somehow be slightly out of skew thus causing lots of pedal movement but little braking action?

It's only me but I would never ever place a disc lock on the back wheel as somehow it just seems far easier to forget about. You need it on the bike but as visible as possible,not only to yourself but potential thieves also.

Hope the p`roblem is not too grave mate.
