My rear brake failed. I picked up my bike after I had the rear tyre replaced and almost straight away I noticed the rear brake wasn't working. It was great before and had a good amount of grab but after the tyre was replaced had only about a 2% grab (pretty useless) so I turned around an went straight back. The mechanic said they never touched the brakes or anything else just removed the wheel. I asked if they had sprayed anything on the rim to clean it and got some on the disc as the break is slipping. He said he told the young guy to make sure he didn't get any on the breaks ?? .Anyway took the bike back to my workshop removed the pads cleaned & sanded them and replaced. All works well now. The interesting thing is that once they had been contaminated the pads developed a glaze almost immediately.

Oh, c'mon...the dealer had to have something to do with this, surely. Were they ok before dropping it off?

Glad all is well now, though.

Yeah they were good before. I think they got chain lube on the disc and then when he took it for a test ride it must have got onto the break pads, I could have got them to pull the calliper off remove the discs and clean them but I wanted to inspect it myself and the jobs not that hard. All good now.

I've never found the rear brake to be that good, only seems to do anything at very low speeds. Maybe I should check mine to see if they have glazed.
Did you need to take the rear wheel off to remove the calliper?, there doesn't seem to be much room to get an Allen key in there.

Hardly, wish I was young. i only gave it a cursory glance but upon closer inspection I did manage to get the job done. A little bit of glazing on the pads, hopefully it will work a bit better now.
Has anyone managed to get the ABS to engage with the rear brake.

Oh no, I was referring to the young mechanic that worked on your bike. :smile2:

Be wary of using wet and dry, sand paper etc on brake pads. The grit migrates into the soft brake pad material and can cause premature wear. Modern materials are not as bad as the older stuff. But ideally use a file to clean the surface.

Agree.
