1998 G1 zx6r brake prob

Looking for some advice
Brakes on my G1 1998 Zx6r r pretty crap master cylinder is a 5/8 on the back
been told this is the prob any 1 know of the easiest & obviously cheapest
upgrade. Do yams or suzuki fit./

Did the 6R have 6-pots on then? I thought they came in with the J1.

this may account for the brakes on the[1] 7R feeling shit at Cadwell
in June.

[1] it's sort of semi-officially Blaney's now, rather than shared.

 

Don't get me wrong, they can still stop the bike - in fact, going down
the steep hilly bit towards the tight-ish left hander I had the rear
wheel off the ground a couple of times; it's just the feel is
absolutely terrible, and doesn't inspire any confidence in them.

"dished"? I've not heard this term before - do you mean that the
entire disc has sort of become curved in section rather than flat?

 

Quite a bit of lever travel, but mainly the amount of braking force
doesn't seem to be linearly related to the amount the lever is
squeezed. I supposed I'm spoiled by the fact on the 'blade I could get
the rear wheel off the ground and pretty much any speed with a little
squeeze from one finger.

OK - this definitely isn't the case, and I don't think they're warped,
because I tried putting a flat piece of wood across various bits of
the disc, and it "fitted flat" everywhere. So it's probably the
calipers.

Tired hoses, or are yours steel?

 

they're already steel-braided, so nothing doing in that department.

In any case, the bike's 100% Blaney's now, so it's his problem.

Being as it is Blaney I suppose he will be swapping them for anodised
anyway so you are right it is not an issue.

Could be a weak right hand. I am assuming you are right handed of
course but have you been doing much wanking lately? You will be
surprised how quick you can lose muscle tone. I am left handed so I
tend to get issues with the clutch if you know what I mean and so I sort
of assume that right handers will have the same or similar with their
brakes.

 

anodised what?

Not much need for that sort of thing for me.

There you go then, loss of muscle tone innit, you need to get a grip.

 

The hydraulic leverage might be the same as a conventional setup
(depends on m/c and slave cyl volumes) but I'd bet it's greater overall
in most designs. The supposed advantage of multiple slave cylinders is
spreading the force over a greater pad area and giving more powerful and
progressive braking. The individual smaller piston will have less force
behind it, you'd be correct in that, and the increase in total slave
piston circumference presents more opportunity for crud and corrosion to
stick things too, so both factors combine to make it more likely to get
sticky.

Problem is with most bike systems is the lightweight construction [1]
and lack of really hard braking most riders do - fear of locking up and
falling off, mainly. In a car with multiple slave cylinders and
power-assisted braking, siezed pistons are relatively rare because (I
suppose) the brakes are used harder regularly which keeps them working
properly. I was going to write that car brakes are slightly more
sheltered, but it's not that true, really - the shit still gets to them.

[1] Looking back on many bike caliper designs, most of them are pretty
shit in an attempt to save weight/cost.

 

Well there you go.

The important thing is that they lick the scrotums of Greek goats.

No. I looked at getting a brand new 2005 RSV and then decided that I liked
the 2006 model more, so I decided to let the 6R do another winter and then
go for the 2006 RSV when the 2007 model comes out.

Of course, the flaw in this plan is if I like the 2007 model more than the
2006 ...

It'll be your age I suppose.

 

Is there a difference? I thought they were more or less the same.

It's amazing what you see when you've not got your gun, isn't it?

That would be the diameter. It will make a difference if a master
cylinder of different diameter is fitted.

 

amongst other things, yes.

 

why /Greek/ goats in particular?

 

Maybe they develop a different flavour after all that TIUTA.
