Hi guys
My latest bit of maintenance has led me to overhaul the rear caliper. I've had nothing but success with Wemoto before so ordered some new seals and pads from there. After finally getting both pistons moving with compressed air, then pulling the old seals out of one side, the new brake fluid seal went in no problems but the dust seal just would not seat in the groove properly. It was almost like it was 20% too big in circumference although it was a perfect fit around the piston alone.
Eventually I held it up against the old dust seal and it is indeed noticeably thicker.

With this extra thickness it won't seat in the groove of the caliper and is effectively useless. I didn't realise Wemoto weren't OEM but I thought they would be better than this. The brake fluid seal seems to be the same size and circumference as the old one but how can I be sure it won't leak brake fluid all over the place when I need to stop.
I will ping an email off to Wemoto and see what they say.
Where do you all get your seals from?
