1998 riviera brakes are rubbing or vibrating

[katherine15]

Hi all,
I recently had my winter tires put on at Kal Tire, and now the brakes hum and vibrate when braking. I'm going in tomorrow to get it looked at, just wondering how and why this happened. I haven't had any brake sounds before this, and I'm a bit frustrated that I left the shop with more problems than when I entered.
The sound only happens when im braking, and stops once the car is fully stopped. (Obviosuly, but thought I'd mention)
The wheels were re torqued, and the tires were balanced prior.
If anyone has experienced this before please share your experience

My guess is the hum is the tires.

I think your problem is the tires.

Tires would make the noise all the time not just when brakes are applied.
The shop has to look, nobody can tell you the cause without seeing the car.
