iam having a problem with these v brakes right here


The Problem happened to me recently while riding.it made a screeching noise i think because the pad on one side of the brakes was rubbing on the rim.but recently i cleaned them like i usually do before the problem happend and it was the front brakes not the back.when i tried adjusting the brakepads on the front side of the bike i made sure they were even and properly toed in(the front pad touches a little before the backside)and the clearance looked not too far or close to the rim but when i brake and release the lever, one brakepad will go back really fast and further than the other while that other one will stick almost to the rim and touch.

i have tried cleaning the brake wires by wiping them down and putting a little chain lube on the inner wire and i also made sure that the brakepad block nuts were correctly in position and had a little grease on them also the rim is in good true and the wheel is properly in the dropout.

a thing i also noticed is when i hold the brake lever down and release it the brakepad will be too close to the rim but when i lightly release the lever again the pad will have more space than before its kinda weird.
