Locked disks while bedding brakes

I am new to having a nice bike (I am in college, and my walmart bike got destroyed) and I got a Giant ATX 27.5 because my brother's bike is a Giant and it's in great shape for being 25+ years old. Anyways, I wanted to get disk brakes because I wanted a lot of stopping power (and they do deliver). But during my first couple of rides, someone walked in front of me while I was going fast so I had to slam on the brakes and I ended up locking the rear tire. I know that it is bad to lock your wheels during bedding. I do hear a very slight wobble when braking with the rear tire now (you can hear it rub harder and softer when braking, but its not that much). What should I do? Should I try to reseat the disk or the caliper? Or should I just try to use my back brake more often to bed it more?

Thoughts? Suggestions?

Thanks

Sounds like you have a slight warp in the rotor, for bedding in, that time has long passed if you have done a couple of rides, that should all happen in the first ride.

Park make a tool Park Tool Co. DT-2 : Rotor Truing Fork : Brake Tools for this if it's really bothering you that much.

I use a crescent wrench to true rotors. It works well enough.

Yeah OP flip the bike over,, set it on the seat and handle bars,,On a rug, no scratching alowed..

Find a very small crescent wrench,, now set your eyes where you can see the rotor as it passes between the disk brake pads..
S-L-O-W-L-Y turn the wheel,,,when the rotor rubs,, back it out and use the crescent wrench that you've adjusted so is easily slips onto the rotor..



Why buy a special wrench from park ?? really ?? everybody already has a little useless crescent wrench,,,that way you've got more BEER MONEY !!!!

Give the disk a tug,,,a little tug to where you see it bend a bit.. move the wheel,,,,repeat, retry, repeat untill the rotor turns true...



"My Daddy Used to tie a steak around my neck to get the dawg to play with me


A special tool to true a brake disk,,,LOL what eva !,,,

I really like being an Old Codger I really Do !
