Cheers for that darrsi, this is why the forum is so useful.  I'll have a look at them both again later.  The one that is "loose" has scratched the inside of the caliper, so that's what made me thing it was "wrong", but if both of yours have play then it sounds like this is the norm.

I did a really thorough clean on the discs and the juddering seems to be gone (or very reduced), so it may have been something simple like the new pads leaving a build up of material in one place (or it could have been taking them out and putting back in, greasing).  I will try a harder stop on the way home tonight to see if I can get it to do it again.   I'm going drop new pins in anyway, and will do the hoses soon so will see how it goes. 

either way, the pad and fluid change made a massive difference to the braking - I couldn't understand why everyone raved about Fazer brakes when I first got the bike!

Yeah, the arrow is pointing forwards, and the tabs at the end of the spring are supposed to be touching the caliper body aren't they? I mean, they don't engage with the pad? I just can't understand why one side has no movement at all, but the other side clatters against the caliper when they are both fitted the same way.  I must be doing something wrong!

Cheers deefer.  I did find it hard to tell if the pads were seated properly in the plate on the front calipers compared to the back, but because the pin went through easily I just assumed it was ok. I don't think I put any copper grease on the front pins either, so will try that.  Looking at the price of discs, I'm hoping I can find a cheaper fix!

Standard rubber brake lines don't generally fail, it can happen but more likely is that they become soft and you lose braking performance. Pulsing through the lever although normally indicates a fucked disc can be the sidewalls of the rubber lines starting to give and although difficult to explain its a different sensation of pulsing that a warped disc would give.

I have had a set of braided lines let go on me, they where fitted by a previous owner of the bike that I owned at the time and must have been twisted to get them to fit, this caused the outer braiding to split and the inner pipe to pop out like a hernia and burst. This is why I now only use the braided lines and the ends swivel to stop the twisting of the lines under installation.

Hi Deefer, how different is the feel between deteriorated lines and warped discs?  I've been getting the chattering/pulsing lever since I recently changed my pads (to EBC).  It's usually most noticeable the more pressure I apply, and backing off the brake relieves it.  The pistons moved freely when I changed the pads it and all the bolts were torqued down properly.  I changed the brake fluid this week (looked like it was long overdue) but I'm still getting the same pulsing.  There doesn't seem to be too much play in the headstock bearings from what I can tell (did the same thing I do with pushbikes, trying to move the fork backwards and forwards with the wheel off the ground).


It's hard to describe the feel, but it feels almost like the pads are chattering out of the caliper.  I've read through a few posts on here stating that new lines made a difference, and I am planning to do put some HEL ones on at some stage using the forum discount, but how would easy is it to tell if the disc is warped without a dial gauge?  I gave them a good clean last night and the front wheel spins freely with no apparent binding.  I measured the thickness when I changed the pads and the disc itself was within spec, though I will check it again.  The lines themselves look to be original though I can't see any bulging or cracking at all.  I am planning to try cleaning the floating disc bobbins at some point as well.

Hello everyone,


Stumbled across the forum whilst I've been bike hunting, seems like a great site .  I've just bought a '99 FZS600, which I'm excited to be picking up tomorrow night  Got my license last month after a year's apprenticeship on a YBR, and can't wait to get out on my first 'proper bike'!  Hopefully the weather gods will stay kind...

I'm based in Surrey, would be good to meet up for a ride/shandy at some point if any of you are local.

Cheers,
Adam
