Options for upgrading Brakes..

[grogan]

This is something I have been meaning to do to my D9 for a long time but not got round to it.

I know the brakes can be upgraded but need to know what will work at a straight swop?

I already have braided lines so they will they fit the new calipers?

Thanks..

I HATE Proboards. You get all the way through writing a message to post, touch the Crtl or Win key by accident when going for Shift and it loses everything.

What I was trying to say was, "Blue spot" 4-pot calipers are direct fit on the forks, but you'll probably need a different banjo connection on the hoses. Some also say you need the compatible master cylinder, but I know others who've used the original D9 one successfully.

There was more, but I'm sure someone else will fill you in.

Thank you bob,

I really hope they just bolt on but I thought I had read that with braided hoses they wont.

A compatible master cylinder would be a R1 master cylinder as a example?

I will find out what parts I need and go shopping on eBay and hope to get this done in a afternoon.

Also if anyone with experience can tell me what banjo connection to? better yet I know there are alot of member in the midlands so if anyone near Coventry got experience of this that can help directly...

Fazer 600/1000, later fz6/ fazer, thundercat/,

Tdm900, xjr1300, fj1300 all use the same master cylinder, you need a couple of spade 4.8mm crimp connectors, instead of the D9 original ones, to operate the brake switch, you just crimp on in place of the D9 ones, and they push onto the fazer type ones, it doesnt matter which lead goes on which side of the switch,original braided D9 hoses will fit ok!

HRHpenfold thanks for the input can I just check with you are you saying I will definitely need a new master cylinder from one of the bikes listed but other than that everything should be ok?

Thundercat is a separate master cylinder and reservoir - I think the others are integral, so I'd go for one of those to save the hassle of having to find somewhere to mount the reservoir.

I have just upgraded to blue spots used standard master and braded hoses. Works spot on.

[grogan]

OK thanks for letting me know I'll give the standard master cylinder a try at first then see if it fits..

[grogan]

well the clear this up they work fine with the braided horses and standard master cylinder no need for any other parts at all.

Cant say I noticed a massive difference but they are more responsive.

The standard brakes work fine if they are well maintained

I fitted blue spot calipers and master cylinder from a 2003 R6. I also used a pair of braided hoses going from the master cylinder direct to each caliper. I did not use the original hoses because I had bar risers. However, I suspected the original might not work because the caliper banjos are not in the same position. I went the whole hog to be sure the hydraulic ratio was right, but if the master cylinder pistons are the same diameter there is no need to change it.

My old brakes were in good condition but were hard to feather and use smoothly. On or off was the best description. The blue spots gave similar absolute braking power but MUCH (MUCH) more control so I could brake with more confidence. A (serious) emergency stop soon after I fitted the new brakes left a black mark from the FRONT tyre but the front end didn't wash out. The original brakes would gave taken me down and the idiot teenager who ran under my wheels.

Stopping would be further improved with progressive fork springs to reduce brake dive. There is minimal compression damping so different fork oils make no difference.

Edit: The blue spots are easier to overhaul but do need a plate clamp and a hardwood block to hold 3 pistons while the 4th is pushed out. The cap tool is handy but not necessary.

Just a minor(ish)point about master cylinders - try to get one from a naked bike, as it will have the boss for the mirror.

I was reminded of this today when I went out on my FZ6S2 - its master cylinder, and most likely other Yams with a top fairing and which have fairing-mounted mirrors, has the boss but it's not drilled and tapped for the mirror.

Yeah I agree a caliper is a relatively simple and nothing has really changed with the blue spot calipers but mine looked really ugly because I'd split fluid on them and all the paint had been removed and I snapped both the bleed nipples plus I think the seals needed doing.


I haven't had a real chance to test them out yet as I only went to round the corner and back to check they work I didn't give them a full grab because the roads have been carpeted with leaves.

So far they do seem more responsive not decided yet on stopping power..

Yeah so long as the pistons are cleaned periodically and the slide pin is lubed and sealed up with a rubber boot that isn't perished (like mine was until recently...) they work pretty well. On the other hand if they're covered in accumulated crud and the pin is corroded into place they'll be horrible! I found braided hoses made a nice improvement to the overall firmness of them, if I hadn't had the calipers rebuilt with new seals at the same time I might have considered just putting the blue spots on but that's what I did...I recently fitted a Fazer 1000 rear master cylinder to the bike (from a 2005 model I think) which I believe has a slightly larger bore, that certainly improved the back brake - I've always thought the rear brake was very good on the Diversion, much better than the one on my Kawasaki ZRX.
