Weird Sound Commin From Rear Right Wheel

i got my back right wheel cylinder replaced today by my schools shop and now im hearing weird sounds

does anyone know what this could be from??

i checked the tire and its on tight

please help!!

also is it safe to drive????I WANT MY CRX BACK!

and from now on, nobody is touching my car unless its me or my usal mechanic. I try to save a few bucks and regret it!

you may want to elaborate on weird - is it like a humming, or is it clanking, etc.?

Could be a wheel bearing....I replaced the rear brakes on an old Mazda once, and I overtightened the hub castle nut, and smoked the bearing withinin 5 miles...I don't know the exact torque number but my experience has taught me to tighten the castle nut, then back it off a notch or two (1/8 to 1/4 turn or so) before you stick the cotter pin thru it.
Bearings are a pain to get pressed in and out, so check the nut before you drive it anymore.

HTH;)
