1980 gl1100

Hello,
I have a 1980 gl with 58,000 miles. I went to change the front brakes because they were dragging. I remove both sides and the fluid which was very old and dark. I then blew the piston out with air and used a brite pad to clean up. I replaced the clippers, bled them but could not get a firm front brake handle. I then removed them again thinking the piston where to tight and would not move, I lightly honed them until the pistons (with seal removed) would move fairly free. I reinstalled and got the same results. What next? any help? Should I rebuild the master cylinder (there is air coming up when I bleed) Thanks
Hal

Have a look at step 8a in How to rebuild your front master cylinder. This tiny port can get clogged, particularly with old brake fluid, which will cause the brakes to drag, and the pistons not to retract. I'd clean that out, refill with fresh fluid, then bleed once more. You'll find it much easier to bleed using a vacuum bleeder like a Mity Vac. These bikes are not the easiest things to bleed the brakes on, particularly after you've had the master cylinder empty.

Yep clean out that hole Very small in front of the one you can see easily..then fill system from the bleeder valve up..use tubing a big syringe..pushes air out ahead of the fluid..makes bleeding much easier..also if you tie the brake lever open over night and let it sit most air will find it's way out..giving the lines a tap every time you walk by will speed the process.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,
