    As far as the scanner bleed procedure, it's really only necessary if the ABS unit loses fluid, I suspect replacing the rear line would not cause that. The bleed procedure basically just runs fluid back and forth in the accumilator to push any air out, at least in every car I've had to do it in.

    When I got the bike I thought the brake feel was due to the ABS (never had a bike with ABS before). It wasn’t until I did maintenance on the brakes that I realized it was air in the brake lines. Now that I’ve bled them myself they’re rock solid.

    I just got mine back from the recall and after a short ride knew it wasn't bled properly. Decided I'd just do it myself instead of waiting at the dealer.
    Did you have success bleeding normally at the caliper or do you have to bleed at the ABS unit as well ?

    I bled at the caliper.

    I just had mine done and rear brake is fine no concerns,a positive among the negatives.

    My recall notice is dated 4/28/20 for my ‘19 S. Still waiting for my dealer to get the parts. Their excuses keep changing.
    So I started focusing on my rear caliper and noticed how hot it became after a ride. Very hot like a hot griddle to cook on. I have always noticed it dragging when turning the rear wheel on the centerstand but thought it was normal.
    Becoming more obsessed and frustrated by my dealers lack of urgency, I delved into looking at the rear caliper myself doing a simple removal and cleaning of the pads. While the pads were out, I grabbed the caliper with a hand on each sliding pin and moved it back and forth. The chattering sound told me there was no grease inside the rubber boots covering the pins. I’ve worked on enough cars to know the pins need grease and the boots keep the grease contained.
    I carefully got some grease inside the boots and racked the caliper back and forth to get it working smooth. A test ride without using the rear brake showed no heat at all when I checked it. When I used the rear brake it was hot but not like a stove. The rear wheel also spins free when on the centerstand now. A great relief for me.
    So I believe that at some point in assembly, the pins were not greased. At this point I have little confidence in the recall being effective if the pins are still left dry.
    Hope this helps.

    I pulled mine apart tonight and can confirm the pins were drier than a popcorn fart. I also noted that the inside pad had significantly more wear on it than the outside pad, which I believe is consistent with the calliper not returning to a neutral position correctly.

    Now that they’re packed full of grease the calliper floats pretty easily.

    That’s my next step. I don’t want to contribute to rumours as I haven’t pulled them apart yet, but it kind of makes me wonder if all the warped rotors....


    Edit: Disregard. The front brake isn’t a floating calliper. It has pistons on both sides.

    To make this easier as I had to stare at this for a bit while I puzzled it out, once you remove the rear wheel and the brake pads, back this bolt out (see pic) and the calliper slides apart.

    Once separated, I coated the loose pin in grease, inserted it into the boot, worked it around a bit, pulled it out, re-greased it and inserted it again. I had to do this several times for each boot.

    I’m curious about the backstory. If you’re going to push it in the dirt you have to be prepared to break a few things along the way, but I don’t know what happened, so....

    Who knows, its FB with no backstory!
    Immediate claims of recalls for front as well.

    It’s hard to tell, but I’m curious if that’s a 270mm fork with a 240mm brake line?

    My first thought too but unlikely we will never know

    It's important to use high-temp brake caliper grease when lubing the pins, which is formulated to be compatible with the rubber bushings. Regular lithium grease will attack the rubber, and as the bushings swell, will cause the caliper to bind, putting you back where you started.

    will ceramic grease do the job?
