    Re: Gen4: check your brake calipers. Leakage. Danger.

    Was going to ask how it was done if you were changing them. I've not done too much messing with the bike yet so unsure myself I'm going to buy a set of calipers soon as the gp4rr I had were 108mm but I have a set of quick release brake lines sat there doing nothing

    108mm is not going to fit BMW, must be 100mm.

    I did calipers/brake lines/abs removal on Gen3, it was straightforward, nothing special

    I havent done Gen 4 yet. I will update later on how I do it.

    Problem is almost everyone’s are leaking. Mines look to be leaking at the mating face between both halves not the seals

    The Berlín plant started again so their suppliers therefore I expect the calipers to arrive soon.

    Brembo is not the parent company of Hayes. Nothing to do with them.
