Front Brake problems

[Dockstrada]

I noticed that my front wheel on my 1198 is almost imposable to spin after I come in from the track.
seems to be my calipers locking the wheel........any ideas

Well used brakes pads that are pushed far out by the pistons and pressing on the disc(s)

Just fitted new pads, the OEM ones were shagged after 1200km.

did you fit the right ones?
a lot of brands offer different thickness of material dependant on what rotor you are using, chances are you have fitted the thicker pads by mistake.

I would say a new set of seals for the calipers

The Pads fitted came from my D16 which were used for 4 or 5 track days ,I do recall the 1198 starting to grab with the OEM pads just before i changed them.
I'm thinking the fluid is getting hot and expanding in the lines.I have changed it once but only with standard DOT4.
May look at Motul 660 factory line has a 325â,,ƒ boiling point .

looks like they're the same calipers, therefore the same pads (oe) between the two bikes, did you fit left inside to left inside, left outside to left outside etc? the uneven wear from the D16 will cause them to not sit right unless they go into the caliper in the correct sequence.
doubt the fluid is the problem, change it regularly though, especially if you do track days but remember, the higher the DOT rating the more hydroscopic it is and therefore requires changing very regularly to avoid corrosion damage to components from water in the system.

No sticky slides or pins ??

Cant say I did the right sequence as they were in the tool box, so they would have gone in randomly.In any case the problem was evident before I installed the new pads .

Nah gave them a clean before fitting the new pads,Also pushed the pistons back with out a problem. I must admit I have been changing them on a front stand and not a head stock stand and not setting the front down before nipping everything up, This could also be the issue.

That assembly procedure shouldn't really matter.
Check the holes where the pins go aren't binding, they may be elongated or out of round
Can't be much more than that.

What "Holes" and "Pins" we talking about  

[Nickati]

The ones that hold the pads in

It dosen't have pins it has springs on top
