I replaced my front rotors and pads on my 1993 Saturn SL(2?) and made sure I used the supplied silicone grease on the contact points, back of the pads and slider bolts. I made sure the wear indicators were not out too far. I made sure the pads were installed correctly, and I cleaned the hub surface where the rotor seats. I bled the brakes and attained the proper pedal height and feel.

I followed the break-in procedure that the manufacturer posted online. The brakes work well but I had a 'not too loud' squeak or chirp from the left side when turning to the right. I reinspected everything and found nothing obvious.

One thing mentioned when I searched is bearing play. I guess the fresh pads sit closer to the rotor. Any tips on verifying or what constitutes too much play? I have a dial gauge but not sure of the proper procedure. Do I have to simulate the load force when turning?

  • Did you checked that the lug nuts are correctly tensioned? – Martin Jun 6 '17 at 15:00
  • Welcome to the site. You said "the fresh pads sit closer to the rotor". That doesn't make sense in context to what you are asking. Did you mean to say the fresh pads sit closer to the bearing? Check out this video on how to check the wheel bearing / hub. – CharlieRB Jun 6 '17 at 15:18

    Maybe your hub is starting to wear out? – tlhIngan Jun 6 '17 at 15:41

    Also, is the squeak constant or rhythmic? Generally (although not "always") bad bearings cause a rhythmic, pulsing, squeak. If it's more of a constant sound then it may just be something rubbing. Often it's some goofy little oversight that causes things like this. – kyle_engineer Jun 6 '17 at 17:35
  • I would check the CV boots for integrity. Brake issues don't vary when turning in my experience. A bearing makes somewhat more sense, but this is usually a growl or a rumble rather than a squeak. Brake parts typically do not change their spatial relationship based on turning. – SteveRacer Jun 8 '17 at 2:48
