Rear Brake Rotor Clearance

Postby cobra04 » Tue Aug 23, 2011 11:22 pm

Just purchased a 85 Interstate, relace rear brakes and rear brake rotor, found a good used rotor, my problem is that I am not sure if the clearance should be the same on both sides of the brake rotor to caliper bracket, I have less room on the outboard side, hard to tell from pic.

I would think that as long as the minimum on either side was 0.7 mm, or about 20 thou , then its ok. If your rotor run-out is more than that, then you have more serious problems than worrying about rotor clearance...
Spin the wheel, and take a careful look at the clearance, as the wheel spins ... the old saying was " a miss is as good as a mile " applies here.

If its not touching as the wheel turns then its good to go.. If the heated up rotor / caliper is touching , you are gonna really hear it !!!

The caliper bracket is located by a spacer between the swing arm side and another spacer on the wheel side. Thethe two spacers are identical, with the same part number (42313 MG9-000) so there really is no way you can get it wrong. The caliper itself is floating and so self aligning.
