Rear Brake problem?
teecee90:
When I refurbed my brakes, just as an experiment I "primed" them by putting a small amount of brake fluid in each calliper cylinder before replacing the pistons. Seemed to do the job as it was relatively easy to bleed the brakes afterwards. May be worth a try next time.

Theirs always a reason i take things off lol :rolleyes

I see, you've got an airlock. Push the pistons all the way back into the caliper, open the bleed nipple, fill the master cylinder and wait until the fluid starts to drip out the bleed nipple. Once it does, bleed them as normal. ;)

do i open both bleed nipples or do them one at a time?
Also I got 2 wiper seals with the kit and I dont know what there for? I got it from wemoto https://www.wemoto.com/bikes/yamaha/fzs_1000_fazer/03/picture/brake_piston_and_seal_kit_stainless_steel_rear_-_by_trk

Open both until the fluid drips out. Nip them up and then bleed the inner one first, then the outer.
Wiper seals, no idea, their made up names is my guess. Each caliper has 2 seals the thicker and flatish surface one is the main seal and goes in the lower and wider rebate. The thinner one with small peaks is the dust seal and that goes in the thinner higher rebate.

Ok thanks I will try, so the wiper seal things are not used for the caliper or anything?

As stated above, I can only assume that's what they have called the main seal.
I'm not really sure quite what you've done. You've said you've bought a caliper rebuild kit and that you've replaced the pistons, but can't get get the caliper to bleed. Which suggests to me you've already done the work? But you're also suggesting these wiper seals, which can only be the main seal based on the list from the webpage you provided the link too. Haven't been fitted?
Have you not replaced any seals but just the pistons? Or only replaced the dust seal (thinner) and left the old main seal in? Or have you only replaced the dust seal (thinner) and taken the old main seal out and not put back a new main seal?
Why did you replace the pistons?
