Hey bicycle experts,
My rear Avid Juicy Five disk brake has been giving me a bit of jip the past few months and it is now time to fix it. It all started after I left the bike on the balcony for a month or two over winter and the brake fluid either expanded, or the tubes contracted. Anyway, for whatever reason the brakes more or less clamped onto the disks. When I tried to squeeze the levers some brake fluid came through the seals of the reservoirs (on both brakes). I did a bit of Googling and found that carefully removing the top of the reservoir to release pressure would sort out this problem nicely, and it did (the front brake is still completely perfect without any further adjustment).
Unfortunately when I was doing the rear brake, my hand twitched or something and I spilt a little bit of brake fluid out of the reservoir. That’s when the problems started. As time had gone on, I’ve had to adjust the bite point of the rear lever to the point where I just can’t adjust it further. It feels like it’s biting, but it’s not gripping the disk. I thought maybe the break pads had worn out, but they haven’t. The local bike shop guy reckons I need to top up the brake fluid.
I need brake fluid. I need to add this into the system. I need to make sure there’s no air in there to fark things up. Usually one would require a bleed kit for this. Avid has one, but Giant doesn’t have any in stock it seems. I’ve been told though that if I’m careful and remove the brake system and hold it vertically, so that the reservoir is at the top, I can add brake fluid without having to worry about air, since it will come to the top.
Anyone have any opinions about this?
