In July, I took my motorcycle in and had the brake fluid and hydraulic clutch fluid changed front and rear…

I know, trust and like the mechanic- his main business is off road vehicles (ATVs, side by sides, etcHe did the research and watched the YouTube video that two Wheel obsession has. He felt confident everything was done OK. He said my brake pads were OK… But I’m guessing that he just did a quick glance and didn’t realize there was one problem child 😢.

Couple rides/approximately 500 miles later I had a grinding in the front 😳

I took the left caliper off and have three pads fine and fourth one totally absolutely worn to nothing. (see the pictures).

Questions:

Is this a brake caliper problem or is this an ABS problem?

Did this pad get worn since the fluid flush or did the mechanic just not realize that one pad was so worn?
I hate to think I am so obtuse that that pad got worn in 500 miles and I didn’t even realize there was a problem 😳 😱

(I did not take the right caliper off. Grinding was obviously in the left one. Right side pads all look acceptable)

Big question! What is problem and what is the solution?😞

First of all, thank you everybody for the replies and help and information.

Second of all, I apologize for double posting the pictures. I don’t know how that happened 😞

Can anybody tell me… Is the brake pad that wore out the one that is interlinked with the back wheel? If so, is that a coincidence or is that a clue?

I wasn’t able to find brake pads this afternoon/evening, and Amazon was (on characteristically!) About impossible to find what I was looking for 🙄. So it may be next weekend before I get pads and the time to fix this. Right now, I have the caliper suspended; brake pads and everything are still attached. I’m not taking anything apart until I got all the parts to put it back together.

Looks to me like the pistons were pretty stuck.
If your "mechanic" is watching YouTube videos, just do it yourself.
ouch. I’m working 12+ hours a day and I would rather pay somebody that has a clue than try and do this when I’m dog tired. My mechanic stayed late and got me fresh fluid for a trip I was hoping to do on vacation. I had problems with an ABS light when I used the foot brake. He researched it and he fixed it. Now, if y’all can tell me something that he messed up, I’m listening. But I still like and respect and trust the guy. (1st time he worked on this bike). And he was able to get me in and everybody else’s three or more weeks wait…

I have pads coming this week and 2 guys in a group I ride with ready to come over if I need it. I’ve been on phone and sending pictures and they think I just had a sticking piston….

pads have 13k miles and all but 1 have normal wear…sucks it wasn’t noticed until wore down to grinding noise, but at this point it’s just put it back together, put some miles on it, and monitor….
