Caliper / Rotor Alignment 82 XJ750RJ

Last evening I completed caliper rebuild & bleeding of brake lines.

I have a mis-alignment on the Left caliper/rotor when looking at the bike from the front. The rotor on the Left is not centered in the caliper as the right caliper is. I have checked and rechecked the front axle assembly using the XJCD diagrams and all appears to be okay.
I am concerned that if I attempt to ride this way I will heat brake fliud, air etc.

Any suggestions would be greatly appreciated.

 

Was it lined up before you started? Maybe the forks are bent or you are
missing a part or have a wrong part installed? If not you must have put a washer or spacer in the wrong place or something although if the disc isn't actually hitting the caliper it probably won't hurt anything.

 

Unfortunately the caliper(s) were frozen up went I started the rebuild and I am not sure of the alignment at that point.

Forks appear to be straight. Bike has been taken care of through the years and to my knowledge has not been dropped or abused. I am the second owner and the original owner is a close friend.

How can I check the forks for straightness?

From front of bike left to right I installed: Axle, into Left Fork, Spacer, Wheel, Speed odometer Drive, Right Fork, Washer and Nut as per the the XJCD diagram. Is there something I could be missing?

Thanks for your reply AZ...

Did you get an answer to your caliper alignment problem? I just got done dealing with the same issue and I found I had to "center" the right (as Im sitting on the bike) caliper by slightly prying between the center bearing and the rotor BEFORE tightening the lower fork retaining yoke.

This worked for my 82 xj750rj. good luck.

 

Im having th same problem. I took the front forks off to add fork boots and now I cant get it to lign back up so that the brakes don't drag... Is there a tricky way to do this? Man, this sucks..

 

You need to tighten the forks in a certain sequence, and possibly adjust the position of one fork leg on the axle to get everything lined back up.

Loosen the main nut, and the pinch bolts. Gently snug everything back up, and "bounce" the forks a couple of times.

Loosen and re-snug the pinch bolts; then go ahead and torque the axle nut to spec. "Bounce" the forks a couple of more times, then go ahead and tighten the "nut-side" pinch bolt/nut to spec.

Raise the front end and spin the wheel to check caliper alignments. You can shift the bottom of the "offside" (not the side with the nut) fork leg back and forth on the axle a small amount if necessary to get everything lined up correctly, then torque that side's pinch bolt/nut to spec.

The key to the whole thing is that the front axle makes up a tight "sandwich" consisting of one fork leg and the axle/bearings/spacers, nut, etc. The other fork leg just grips onto it, so it can be adjusted laterally a small amount to get the calipers aligned.

Which side is which varies from bike to bike depending on which side your axle nut is on. THAT'S the "locked down" side, the other can move along the axle as needed.

 

Im working on it now. Just loosened up everything again for millionth time. Thanks for the tips. The repair manual is quite vague on some things.

 

Just edited my reply, I had it "handed" then I realized the bikes vary as to which side the nut is on.

Anytime. I'm trying my best to plug the gaps in the manuals; finishing up the rear wheel bearing replacement piece now. We'll get to front forks when I do front wheel bearings or tear my 650 apart, or if Schmuckaholic beats me to it.

If you're referring to the factory manual, they assume a certain level of prerequisite training; it was aimed at dealership mechanics. It does get frustrating at times. The Haynes is just all over the map.
