does anyone have this master cylinder without the dreaded soft brake lever? Is it supposed to be replaced regardless...and does the 5/8 one the better setup? :???:

 

[BlackBeauty]

I had my 14mm replaced two weeks ago with the new 5/8" and the feel is much better and firmer with the bite occurring after less initial lever travel.

Previously with the 14mm, the brakes were striong but required so much lever travel that my fingers were getting touched by the lever.

Hope that answers your question.

After a few thousand miles - I MAY also get the teflon coated pistons but I am happy as it is now.

The last long ride I took I became "fed up" with my 14mm and decided I'd find Hayabusa calipers or something else that would fit . Just by chance that was the same day that the "recall" came in so I decided to wait and try that. I haven't braved the cold yet to get it done (cold snap for the last three weeks) but will get it there eventually. I hope it helps. If not I will find alternative methods, possibly with other calipers.

To answer your question, I do know of one guy who doesn't find his 14mm to be "that bad" but he has remarked about how soft mine is.


Wait a minute...

:-D Dealer replaced mine a week ago, so far I've only been on a couple of short rides, nothing challenging. I never really had a complaint about the brakes other than they seemed to take a lot of lever travel before they took effect. That said, the difference is night and day, I can now use two fingers for braking an use the other two for throttle control, before, if I left my fingers on the throttle they would be pinched by the brake lever.
:asb: Long story made short. If you've got a 14 have your dealer replace it. Just beware and don't try to grab as much brake as you did before.
BTW in my opinion just looking at the new m/c it appears much different from the old one.

I know the brake problem is more of a 1050 issue than the 955's, but I found that my RS's brake lever was too soft an action for my liking, and definitely softer than on bikes I've previously owned. I was able to pull the lever right back to the grip. That said, the brakes actually worked well and consistently. Having read a few threads on this, I acquired a Nissin 5/8" master cylinder from a Kawasaki ZX6R and fitted that. The action is much firmer now; I can't pull the lever all the way back, and much prefer the feel. The cylinders looked identical except for the numbers cast into the body; 14 v 5/8.

 

[Suncoast]

Dusty did you replace the calipers as well or only the m/c?

 

[Dusty]

Suncoast, I only replaced the MC. For me, it was a feel issue rather than braking performance. I did think about Tokico 6 pots but I'm not sure the bike needs them. Could be just more unsprung weight and aextra cost that isn't justified.

Dusty,

Like you, I found my RS's brake lever was too soft, I can pull the lever right back to the grip. Tried cleaning stripping etc which improves things for a few weeks, but then back to pulling the lever for about an inch before anything happens. Just got a complete Tokico 6 pot system from a Kawasaki, and will fit as soon as I've got some pads (and the temperature in the garage climbs above freezing), hopefully this will improve things

 

[katrider]

I've also read about the Honda 929's master cylinder being a direct (or near direct, maybe one small mod...) switch with much better feel.

BTW Dusty, what year was the ZX6R???

[Dusty]

Stevesrs, Please let us know how well the 6 pots perform. I may yet go for it.

Katrider, There is a Honda CBR900R MC that fits with a small modification to allow the brake light switch to be activated.Click here, look at Mods section. The MC I used was from a 99 ZX6R and required no modification; straight swap. I know this is of no interest to you, but UK guys may wish to note that I got it from MC Motorcycles in Hull; tel:01482 225790. Steve at MC was very helpful

 

[SR1]

Stevesrs, could you tell us exactly what Kawasaki they came from?

 

[Panthers_Den]

These are some of the "donor" bikes for a direct replacement of the 14mm MC to a 5/8" MC:

Kawasaki ZX6R 1998-2002
Kawasaki ZZR600 2004-2006
Kawasaki ZX9R 1998-2003

These are some of the "donor" bikes for the 6 piston tokico front brakes:

ZX6R 98-02
ZX6RR 02
ZX7R 96-03
ZRX 11 and 12 99-04
ZX12R 00-03
ZX9R 98-03
Suzuki GSX1300R Hayabusa all years 99-06

These have been posted quite a few times already and is also listed on the Triumphrat Wiki Page located here which is also listed in the stickied topic "Sprint ST Aftermarket Part Numbers".

 

[SR1]

My apologies for not looking. I never think that that list will have what I'm looking for...I will start looking there first. Many thanks!

 

[stevesrs]

The six pot Tokico calipers/master cylinder are from a 98 Kawasaki ZX9R, from flea bay £60, all I need now is some new pads, although it's looking doubtful if I'll get them this weekend due to the snow

Yea, don't let the topic fool you. Anything that can fit on the Sprint ST I throw on that page regardless of what it is. Even things that fit on people and not the bike are on there ;-) (e.g. safety gear)

 

[Dusty]

That's a great resource, Panthers_Den. Thanks. I, too should check out the other places on this site. In fact, if we all did, there would be a lot less time spent on chitchat! I use the search facility a lot but I find it less rewarding than other search engines.
