My girlfriend's son recently acquired a pre-owned Scott Aspect 760 for Christmas (2021 model) - essentially brand-new and ridden once or twice, if at all.
We noticed the other day that something seems to have popped out of the right-hand brake lever:
It seems to me that the circlip holding that "piston" in has popped out - the lever hasn't been struck as far as we can tell, there's no damage to the lever whatsover.
I believe the brake system is the Tektro HD-M275, and the Googling I've done so far suggests that this "piston" is the "reach pin", but I can't find any info on how serviceable this is:
(the picture I found with the reach pin listed was for Auriga levers, items 3/4/5):
There's some slight fluid weepage, so a refill and bleed is presumably a certainty?
Our options at the moment are:
- Attempt to refit the existing reach pin and circlip, bleed the system and see how it goes.
- Buy a new lever, refill and bleed the system.
- Book it into LBS and let them deal with it (they don't have any availability for several weeks though).
I don't want to waste any time with option 1 if it's unlikely to be successful, likewise it would be a shame to spend time and money on option 2 if it's fixable.
Does anyone have any knowledge of the operation and servicing of these levers?
NB. The bike is still under warranty - if this is a manufacturing fault with the brake lever, I can chase up with the store (not my LBS) where it was originally purchased.
