Since I'm new to biking (bought first bike 2 months ago) and plan on starting to do some serious riding very soon, I decided it's time to start doing check up. I checked my brakes today. The front right brake pads have a few mm. to go. The front left brake pads look like they have only 1-2mm. So I need to replace them very soon.
Do I have to replace both sets of brakes, or can I just replace one side (both on that rotor) and wait for the other side to wear down as well before replacing those pads? I have a feeling that having different make brake pads on each rotor is a no-no, but just thought I'd check.
Is this uneven wear something I should worry about? I figure it was just the previous owner replacing one side before the other. Can it be anything else more serious?
I plan on doing brakes, oil change, tire pressure, check chain tension, and check air filter all by myself (and youtube and manual). Anything else I should look at?
