You may not have opened up (manually reset) the brake pistons sufficiently. Typically, I remove the brake pads and use a plastic tire lever to push pistons back as far as possible. If do not push har …

As you dial out the barrel adjuster on the brake lever you pull more cable by effectively lengthening the cable outer (aka cable housing). By pulling more cable you change the starting position of the …

Disc brakes are reasonably tucked away on the frame and fork and as such pose relatively little danger relative to other components such as the large chain ring (which I have experienced in a peloton …

With mechanical discs the force from flexed brake housing can often make adjusting caliper position difficult. Try disconnecting the cable and housing, then adjusting the caliper position by dialing …

It is likely the temperature change combined with imperfections in your rotor. No rotor is perfectly straight, all will have a slight deviation from centre. The colder weather can make metal contract, …

It sounds like you reset the caliper piston correctly. Most hydraulics will automatically set the brake pad distance as you cycle the brakes. This is why it got firmer and started rubbing. Next I wou …

The real problem with quick release skewers on a disc brake bike is that all skewers are not created equally, and some cheaper skewers distributed on QR disc brake bikes were not up for the task (henc …

It was late when I tried installing some replacement brake pads, and for some reason the top of the replacement pads wouldn't fit properly into the channel that is supposed to guide the pads (lower pi …

The "sharpening a knife" sound you describe is likely the rotor lightly touching the brake pad (as mentioned in @Jackson's answer). This can happen if the rotor slightly is out-of-true (i.e., slightly …

I've had this happen as well (BB7 as well). The only working hypothesis I have is that the rotor has small imperfections, for example small deflection, which is made worse by heating during braking re …

Flipping is not feasible as rotors are directional in design. You could rotate between wheels ensuring they are in the correct orientation. But I am not sure what you gain, eventually you will need t …

Are there any reasons not to build road bikes with through axels, even if they are not disc brake equipped? Is this a trend we might see as manufactures produce more pairs of very similar road disc …

There is no such thing as the "perfect frame." This is why the N+1 rule exists: Rule #12: The correct number of bikes to own is n+1. While the minimum number of bikes one should own is three, …

As long as the skewer is set with sufficient clamping force this QR disc brake setup should work fine and from a practical standpoint there will be very little functional difference between this setup …

In order to brake you apply force on the brake lever that is then transferred to the braking surface (e.g. disc and pads). The advantage of hydraulics is the efficiency in which force is transferred …
