Fitting FZ1000 Caliper to FZS600

[unfazed]

OK so...

Thanks for the idea riedrider.....might need it IF filing them down does not work....i have to try that first...

Unfazed...i shall give it a bash...

It is more important to have good unpitted guide pins as pads use these to slide within the caliper and wear on the caliper body is more often due to worn corroded guide pins and/or poor fitting spurious brake pads. 

Any sign of pitting on the guide pins which cannot be cleaned or removed, means they should be replaced. The guide pins are rarely replaced and when they wear it exacerbates the wear on the caliper body.

ok thanks unfazed, sure enough there are some wear marks on these, but i can pick up some new ones easily...

have had a go a cleaning them and with a tad of wet and dry they have come up nicely - smooth enough as well....so it looks like it was just a layer of rubbish..

The caliper should still work but you might hear a bit of a clunk when you hit the brakes because the pads will have a bit of movement

i will look at the pad guides tommorow  night i suspect - then re-assemble and bleed then see if they work ok...

Correct me if I'm wrong, but doesn't the rear R1 bluespot have the same piston diameters as the fzs600 standard caliper.


I know the pads mount differently, from the bottom leaving the caliper more open to remove water/road crap, but if the pistons are the same it won't affect brake feel at all.

hi, i think the FZS1000 caliper i have put on has larger bore pistons, than the FZS600 stock one - i am not 100% sure, main reason for the change was my rear caliper was in appauling condiiton

Be careful with R1 calipers, i do not think they transfer, they look identical but are different, i know that XJR1300 ones can be used in some cases

I am sure a few on here will comment when they see this so could confirm the pistons are the same or not....

If i get time i will look as they are both in the garage

I suspect you will get different feel and performance as thats one other reason people upgrade, but i literally had no choice and did not see any well conditioned FZs600 ones on ebay

Have a read of this...

The FZS1000 rear caliper pistons are 5mm larger in diameter, 43mm as opposed to the 600 at 38mm.
However the important bit here would be the master cylinder, but the master cylinder on the 600 and the 1000 are exactly the same part number 4BP-2583V-01.
With the 1000 rear caliper on the 600 you will have the same braking setup as on the the 1000 and a caliper less prone to seizing  :thumbup

For info. This master cylinder was first used on the Japanese only market XJ400 and is used across many bikes in the Yamaha range[color=rgb(0,0,0)][/color]

You are correct the pistons in the R1 rear Bluespot are also 38mm diameter

I thought so.


As a patternmaker, I was planning to make a new bracket to fit the R1 bluespot onto the fzs600 as I know they don't fit the standard bracket. However, on finding out they were the same piston diameter, and realising you're not really gaining much, other than being less prone to seizing I decided not to bother.

so been at the caliper with a file and a little wet and dry, just took the lips off and its nice and smooth now, old pads seem to fit ok with not a shocking ammount of play, waiting for new ones to arrive...

Nearly look as clean and smooth as your office hands anutz
Well done mate

Just looking at re-aligning the back wheel and then will fix the caliper in place again.....so almost there - need to add some pics of the alignent once i have the wheel sorted...

[anutz]

OK so i may have an issue...

The 2 pistons - should they retarct FULLY and sit flush with the caliper internal surfaces with the bleed nipple loosed off one each chamber...

I suspect they should as all my front ones did - anyone comment..

If so this might be something i need to look into as right no i doubt i would be able to get the pads in and seat the caliper....they both are about 2mm proud when fully retracted...???

will try to pump them out a little them push them back in anyway...

If the protrusion is equal on both sides it might be normal for this type of caliper.
You can measure the gap between the pistons and the thickness of pads and brake disk and easily calculate if it will fit.

Yes they are mate.........................

Every home mechanic needs one of these!!!
