Ive done some maintenance work to the R1 today, cleaned the front brakes and replaced the pads.
I took a few pic's as i went.
First start with this, because it has 4 piston calipers the disks need to be semi floating, but they can't do that if they are full of crap.
So I put the nut and bolt with a washer on each side, then use a ratchet to spin the bobbin round, spraying brake cleaner into each one.
Next get the old pads out and take the caliper off, see the build up on each piston, that needs cleaning off, before:
After:
New and old pads, they did have abit of life left, but not much.
Pad holding pin has some slight surface rust.
A light going over with sandpaper takes care of it.
Right side back together.
Leftside back together.
Next job is to bleed the system.
First bit remove the reservoir cap.
Righthand side one first, put load on the lever then open the bleed valve.
I don't know if the pic shows the air coming out, its done once only fluid is coming out.
With both calipers done, its time to do the master cylinder.
This bike has a Brembo unit so has a bleed valve up here, my brother's bike doesn't.
Then to finish it off, check the level in the reservoir, keep in mind its on the sidestand at this point.
That should do it.
