Rear Brake Caliper Rub

Postby DpaulTN » Sun Jun 26, 2016 1:27 pm



I know that you have seen this question before, but this is different from all the issues that I have read and researched. 1993 GL1500 Aspencade / 50K miles / Third owner / New to me
I have removed the rear wheel, replaced the tire, and the brake pads. Cleaned and lubricated the splines both on the wheel assembly and the shaft drive. When I was reassembling, the brake caliper bracket rubs on the inside of the rotor. If the issue was bearings, I figure the rub would be in the outside. The washer is between the swing arm and the brake bracket. It doesn't take much pressure on the brake caliper to make it stop.
I added a thin brass washer to the washer against the swing arm. It did not help. Still not convinced that its not the bearings.

Thoughts?

I have gone to the All Balls Racing website and rolled the dice on a new set of bearings. I have no clue if that's not the issue.

Was it rubbing before you had removed the wheel? If not, I would guess that the spacers are in incorrectly.

Someone else ask me that same question and I didn't know. The back side of the rotor is not smooth like the front. If I was to guess, with the roughness of the rotor, I would say yes, it was rubbing before.

I believe someone has assembled it incorrectly. You shouldn't have any contact when spinning the wheel. I no longer have a manual for the 1500, but I'm sure someone will come along that can post the breakdown of how the spacers are to be installed.

Thank you for the thoughts and the photos. That's the way I have it installed. The one thing that bothered me, putting it back together was that the spacer - when it's installed against the bearings - has about a 1/8" gap radially between the spacer and bearing seals. I can turn the spacer around and it will touch the bearing, inside the seal. The photo that dingdong included shows that there is no play in the spacer vs the bearing seal. I'm leaning more toward a bearing/seal issue now.

There should be no gap there. The rubber seal touching the spacer is the sealing point. I really can't picture a seal shrinking that much to leave a 1/8 inch radial gap. Might be time to start looking at the bearings. Take the tire/wheel top to bottom and see if there is any side play.
