Thank you! I've been having trouble finding the clarity you showed me.
mine is squeezing without hitting the brake. how do I back off the caliper pressure ?
After careful consideration (frustration) and 30 minutes trying to align my brake pads and rotors, i need a new bike
Okay, so I have done this 100 times now, I have tried three new discs and am positive they are true. Is it possible that the hub itself is not machined properly? This is on a new wheel with about 2000km on it but it's been rubbing since brand new?
But when I secure the caliper bolts, it tends to shift to right, even when holding the brake lever hard. This makes it impossible not to rub aggressively. So what should I do?
Best video on the subject–concise, clear, and comprehensive! Thanks.
Easiest way to make sure your wheels are seated correctly; stand the bike upside down first. This is also the easiest way to spin your wheels and check rotor alignment without a stand. Also while I've occasionally had success pulling the brakes for centering, it often doesn't work because the fork boss mounts aren't perfectly surfaced and as you tighten the bolts the caliper shifts out of alignment. The same thing can happen if there are no washers on the caliper bolts so the twisting movement of the bolt head moves the caliper as it tightens in the last turn or two. This often requires a lot of pressure to oppose the movement while you tighten the caliper down.
What is desired gap between Pad and Disc each side?
really well explained and yes thanks for posting such
