Brake calipers upgrade

[jdeitz1979]

I'm looking to upgrade my front brakes on my '91 Vmax. I have currently a set of 2000 R6 fronts that were given to me that do not fit. The bolt pattern is a bit longer then stock. Anyone here have '91 stock forks that has an upgrade, and if so, what are you running?

1993-2007 = 298 mm rotors, & 100 mm o.c. slider spacing for calipers. The early R1 calipers should fit. Are your downtubes 43 mm dia.? They should be.

He has a '91 which should be 40mm forks
93-07 have 43mm.

That is correct. The R1 calipers will NOT fit without adapters. Here's the options we provide:
Front:
Option 1 - DUAL Hayabusa Conversion
$60 - Adapters
$150 - Used 298 mm Rotors (I have some new available as well for varying pricing)
$150 - Pair Used Hayabusa Calipers
$80 ($40 set) - New Pads
*Optional - $110-150 - Pair Brake Lines (or 3 line kit - price varies depending on the option chosen)

Option 2 - SINGLE Hayabusa Conversion:
$40 - Adapter
$175 - 320mm Aftermarket Rotor
$100 - Used Single Hayabusa Caliper
$40 - New Pads
*Optional - $50-$80 - Single Brake Line
The advantage is cheaper cost then doing as a pair and less reciprocating mass for even better handling.

Option 3 - Dual Nissin 4 Piston:
This setup doesn't work as well as the other options but is less expensive and still better then the 2 piston brakes.
$60 - Adapters
Reuse your 280mm Rotors (or get vented aftermarkets we have available)
$50-$150 Used Calipers
$70 ($35 ea) - New Pads
$110-150 - Pair Brake Lines (or 3 line kit - price varies depending on the option chosen)
Some of the listed calipers require longer brake lines depending on if you have a lowered or stock height bike.



Rear:
Option 1 - Relocation Bracket
$45 - Single Relocation Bracket to use OEM caliper with 298mm rotor size.
$100 - Good used OEM 298mm rotor (Other new ones available too).
*Optional - $50-$60 - Braided Brake Line

Option 2 - Hayabusa Conversion
$40 - Single Bracket - You must Modify (I have pics of what to grind for these to fit)
$100 - Good used OEM 298mm rotor (Other new ones available too).
$100 - Single Hayabusa Caliper
$40 - New Pad Set
*Optional - $50-$60 - Braided Brake Line

Option 3 - R1 Conversion
$150 - Custom Rear Brake Mount
$50-$150 - Used R1 Caliper (price depends on year/condition)
$100 - Good used OEM 298mm rotor (Other new ones available too).
$40 - New Pads
*Optional - $50-$60 - Braided Brake Line

Oops, I missed the 1991 reference, I thought he was talking about a 1993+ model. I saw the question about 1993 rotors being bigger, and based my response off that, I am corrected.

I currently have the r1 set up on the rear. This fall I will be doing a rear rim conversion and the front fork swap. So maybe I will just wait till then

'Busa has 320mm front discs & only 240MM rear..... because you really don't need a larger rear rotor.

Thanks. It’s coincidence the mention of the busa’s specs. I’m in the process of getting my swap done now. Busa front forks and wheels.

HH pads are a good upgrade to better braking. The early single piston front calipers are something I wanted changed right away. At the time the Nissin 4 piston caliper adapters were the best & only option. They still work very well. Stock rear calipers are decent.

Another option for 85-02 front end is fit Harrison 6 pot billet callipers straight on with no nonsense conversion . Stainless steel lines straight to each calliper race style using original master cylinder. New race lines come with the required banjo bolt that allows the lines to each calliper. Believe me the braking is brilliant!

I think you have a typo, the 1985-1992 are the smaller caliper mounting spacing (84 mm), while the 1993-2007 are the larger caliper mounting spacing (100 mm).

Because the pics w/the measurements are not stereoscopic, it appears they are not on-center for the brake caliper mounting holes, but they are. Pic #3 is the 100 mm spacing 6-pot caliper next-to the 1985-1992 fork slider spacing caliper mount holes.

The last pic is of the late-model FZR1000 three opposed pairs (6-pot) of pistons, a popular upgrade. Pic #2 is the spacing they have (100 mm).

I am considering the Harrison 4 pot calipers for my 86. Have you heard anything about these?

Early r1 calipers, as in what years?

98-03 R1 blues spot and gold spot calipers
FZ1, and R6 also offer bolt on options. Years vary.
There are some others out there that may carry the same calipers but I've never really bothered to check into it. I don't the R1 calipers are all that much of an upgrade to a 2003-07 vmax.

Thank you. I forgot to mention bike is a 1992, so those calipers wont work, right?

NO.
None of those calipers will work on a 92. They only fit the '93-07 vmax.
Send Sean Morley an email about buying "Busa Adapters". The cost is minimal. Go to ebay and buy a set of gen1 Hayabusa 6 pot calipers (99-07). Buy a set of 93-07 vmax rotors. Bolt it all together and your brakes will be great.
