front brakes holding up. HELP!

Postby tyrevere » Sat Mar 24, 2012 2:54 am



i just recently purchased a 1988 GL1500 and i ride it everyday. i took it on a 6 hour ride and the next day the front brakes seem to be dragging or holding up. if i use the rear brake peddale it doesnt do it, but if i use the front brake lever it holds up tight. after reading through the articles here what would be the first step in looking at what is wrong...the caliper or master cylinder? all hellp would be great thanks!

Welcome

Can't help too much other than my gl1200 has a split brake system where the front brake lever only works 1 front caliper and the rear pedal operates the other front caliper and rear, but I would start with just removing the caliper and pads and just cleaning the piston/s. If you havent done this before it is a simple job, I just typed 'clean caliper' into search box and found several posts which could help. Guarentee others will leave more helpful replies. you've come to a great site.

Had the same problem. Was due to the pads not retracting when letting off the brakes. Think t was due to crap in the brake lines, because when I bled the brakes, all settled down back to normal.

It can also be the return port plugged in the handlebar master cylinder.Also,on the calipers.Remove the seal and gently scrape the oxidized aluminum from the groove.It does have a tendency to swell and bind the piston.
To easily verify where you have a problem.Lift the front wheel and turn.Open the bleeder on the left caliper,if the wheel is still dragging,clean the caliper.If it frees up,clean the handlebar master.
Its the same system as the 1200 and later 1100
