Rear Rotor

Postby Richastle » Wed Jun 22, 2011 1:56 am



Hi Goldwing enthusiasts.!! Im new here but not a new Goldwing owner. I have a 1980 Interstate that has treated me well for many years and have just purchased a 1983 GL 1100 Interstate. It needs a little tiddling but runs pretty decent for almost 30 yrs old. Im having some problems getting enough pedal into the back brakes, and need a new rotor. My supplier in Canada, (Vancouver) says they are obsolete, and I should look to my southern neighbors for a decent used one.. Any suggestions?. I may take the one off of my 80` but it doesn`t look a whole lot better.. I`ve bled the system and have new pads so the rotor is most likely?..

I doubt that the rotor is the problem. Even with a worn rotor the brakes should still operate properly. Probably still have air in the system. As a last resort I would consider rebuilding the master cylinder as well as the wheel cylinders before I spent money on a rotor.

Agreed - the rotors rarely wear, unless something is wrong. More likely you've got air in the lines, a master or caliper in need of a rebuild, spongy brake lines, or all/some of the above.

Thank you!! Assuming my rotor wasn`t the problem, I switched the pads from the front brake to the rear and noticed a big difference. The pads were new, but must be defective in some way.. Problem solved!!

Assuming you retracted the pistons somewhat in order to swap the pads, it's possible you had air in the lines, and just pushed the air bubbles up into the reservoir solving the problem. Were the pads you took off glazed, perhaps?

One big problem I have noted with rear disk brakes is that they collect road debris. I have had to take my rear bads off several times and clean the surface of oil/grease from the road.
