Zero Knievel Posted December 6, 2023 Share Posted December 6, 2023 If the brake system isn’t computerized, is he riding the brakes and not realizing it? Quote Link to comment Share on other sites More sharing options...

SwampNut Posted December 6, 2023 Author Share Posted December 6, 2023 Yes, and still. He says that the master was overfilled when new. So was the front. This is dealer prep I think, so his dealer seems retarded. It's easy to see the condition of the inside, non-piston side pad by glancing at the bike, and he was satisfied that it was good until it started grinding. The gender thing was just fucking with you all after Mike said not to make it easy yet. But also because I had emphasized that "he" didn't fuck it up, the dealer did. I'm actually not convinced this was the problem. Quote Link to comment Share on other sites More sharing options...

tomek Posted December 6, 2023 Share Posted December 6, 2023 (edited) Well, I've found this. Webster definition of cheaply made chinasum hardware. They put POS like that on 20 grand bike. Lol. Congratulations. It is easy to see why that has happened. Once pressure is applied that "caliper" flexes like banana, and locks pins in place. They can't slide, hence one sided wear. Here we go. Caliper in question. Edited December 6, 2023 by tomek Quote Link to comment Share on other sites More sharing options...

SwampNut Posted December 7, 2023 Author Share Posted December 7, 2023 He said he figured it out. I bought it. Now I'm thinking...maybe not? I'm thinking out loud. He's convinced it's fixed. I'm not sure how to know. Quote Link to comment Share on other sites More sharing options...

He's convinced it's fixed. I'm not sure how to know. Is the regen level changed by a pressure switch or a mechanically linked switch? If it's pressure it could possibly be caused by an overfill. If it mechanical then the lever is being held by him or something. I'm assuming that the wear and regen are related, which seems likely.

SwampNut Posted December 7, 2023 Author Share Posted December 7, 2023 Pressure switch, no mechanical switches on the rear lever (but yes on the front). I also don't know if the brake light and regen are the same switch, I think no. Being grossly overfilled should fix itself over time though, right? Or, I guess, maybe he got all the major wear up front. Ah, right, that's likely, I was thinking it was wearing more all along. Either way, both ends were filled to absolute max apparently.

SwampNut Posted December 7, 2023 Author Share Posted December 7, 2023 Glancing at mine, I think you could overfill and pressurize it as you screw on the cap. His bike is a low end model, with a much cheaper brake system, and no clue if that translates. But seems like it would. I've got their spic Brembo line.

superhawk996 Posted December 7, 2023 Share Posted December 7, 2023 If it stops having the low regen problem it's fairly safe to assume that the wear problem is also solved, but it would be a good idea to check the temp after a ride to be sure.

CALCXX Posted December 8, 2023 Share Posted December 8, 2023 (edited) Can the disc play a part in this? Not a word of the condition of the disc. Nothing showing on the disc ? Perhaps the piston to bore clearance is more than it should be and lets the piston rock for a microsecond all crooked before it settles? That is the backing plate showing the anomaly's.

SwampNut Posted December 8, 2023 Author Share Posted December 8, 2023 The disc was fine until this, and he says it's still not bad. The only oddity found was the extremely full reservoirs. Quote Link to comment Share on other sites More sharing options...
superhawk996 Posted December 8, 2023 Share Posted December 8, 2023 I had a bike that would loose front brake while parked due to an over-filled reservoir. The first time it happened it it was fine on the second pump, Hmmm...that's odd. It got worse and worse. The only new bike I've ever owned, China bike, overfilled so much that I don't know how they pulled it off. Once drained it was fine.

SwampNut Posted December 8, 2023 Author Share Posted December 8, 2023 So I guess it's probably confirmed, and my second-guessing was unwarranted. He said that today, the light and regen are working normally. I'm still suggesting a full bleed when possible. Quote Link to comment Share on other sites More sharing options...
