Pic of the 14 mm handbrake pump? Or master cylinder

[HansJ]

I bought a 2nd hand pump maybe two years ago, and I thought it was for a R6, modelyear unknown. It came without lever, so I used the TRX lever, which almost ended with a catastrophy. The piston didn't come all the way back out, so after a trip around the block, my frontbrake locked up. After taking off some material of the lever, it all worked.

More out of an urge to know everything is OK, than a real need, I thought I'd buy a repair kit, so I brought the pump to the bike-shop. After trying different levers withou any success, one guy passes by and says, "Hey, that's a Nissin pump, that's Honda!" Despite my doubts, we managed to find a repairkit for a VFR800 that looked exactly as my parts. But we didn't find a handle for a Honda that would fit. So, my question is, what make is my pump? The only text I have on the pump is Nissin, and the nr 14 (as 14 mm, instead of TRX's 5/8"). Can anyone help me by telling what markings their pumps have, or even provide a picture, together with info from which model the pump is, then I can find a lever that fits as well. I will try to get a picture of my pump later.

We call them master cylinders so I've edited the title - hope this helps you (phuk)

Same markings as yours - mine is a YZF600 item. The original and the 14mm ones are both Nissin master cylinders and if I recall correctly Nissin is indeed owned by Honda, as well as used by them on lots of bikes. You should just need a lever to fit. If a YZF-600-R one doesn't fit, perhaps it's an issue with the master cylinder and not with the lever you're using?

@Phuk; thanks, I should have known that, was too quick translating the Swedish slang expression...

@idl: I knew it! Damn sales people, and this place used to be my favorite. I insisted, so he called a colleague, who stated that there has never been a Yamaha with a Nissin cylinder... MFs
Do You know which year your came from? They seem to have changed, I did a try a month ago, without having my pump (OK,OK, master cylinder...) with me, and they told me there were 3 different cylinders for the R6, depending on the year.

it's been posted before, but you can mod the TRX lever to work with the 14mm master or use an R6 lever.

@youngy:
yup, I know, my lever is a TRX lever that I modified. The key issue is which R6 modelyear that will fit, as they differ slightly over the years.

I have attached pics of the repair-kit, looks pretty alike or? Only difference is the length of the spring. And this is a kit from a Honda VFR800... The other pics show the mastercylinder. If anyone can confirm modelyear, I can go back to the shop and order the lever (they did not have any in stock this time). "No Yammies ever had the Nissin cylinders", tossers...
Cheers,
Hans

Looks like the master cylinder i have. I ordered a lever from Kedo - TRX I think I ordered, and it turned out to be an R6 lever!

afaik all pre-radial R6s are the same.

[gregs656]

My VFR400s looks exactly the same.

[HansJ]

My VFR400s looks exactly the same.

Even a 125 Honda shared the same article nr, so I guess it's been on many different models.

Hi Hans!

Since you can understand German very well: just look at the thread here at the German forum.
There you'll find a few pictures and a few dates about the original/R1 master cylinders and the levers.

A short version for the other readers here:

Original TRX master cylinder is a Nissin and marked "6A 5/8"
(as some of you might know already ... )

(My) R1 master cylinder is a Nissin and marked "9K 14"
and the lever that fits is from a R1 model year 2002 - but an accessory lever (carbon look) for the TRX fits as well (I've got no original TRX lever for trying but I suppose that should fit, too)!

Hope it is of some help.

Linking greetings from Munich!
