Well its almost been a year and I'm off around Australia tomorrow and its all happening.
Im a bit time poor, so I budgeted a couple of days to do everything I needed to do to the bike. Anyway, the last thing I wanted to check was the rear caliper as it was never really 100%.
Anyway, I still had to pop one of the pistons out with air, regreased and put it back in, and I also noticed the brake pads had not worn evenly. When placed together they are worn 2 degrees off to the left, instead of being straight up and down (say 90 degrees) with even wear. Also, that 14mm bolt never really went back into place, leaving a 3mm gap.
I think the caliper is not sitting parallel with the rotor, and the bolts are to blame.
Stupidly, I just decided to outsource the work to a mechanic so I could get my study done for an exam I have today. Anyway, they dont know anything about ST's and I regret sending it there as it was supposed to be a quick and easy job - now however, we are at 4 hours of labour while we learn on the job so to speak.
In the past, I've tightened up the smaller bolt first towards the rear of the caliper, and then tried to tighten the front. Am I doing it wrong somehow? You'd think with 4 moving parts that it would be straightforward. If anyone could chime in and save me a dollar or two in labour, I'd be happy to hear it
