Ltd 750

I have a Kawi LTD 750 from 1983 and the rear brake is sticking. The pedal actually sticks down and will not pop back up unless I pull it up by hand. I was curious if anyone had any insight to this issue. If WD40 would just help or if there could be an underlying problem?

You will have better luck in the Vintage section as your bike is not generally considered a cruiser. You might also identify as to whether the bike is the twin LTD model or the 4 cylinder LTD model as both were sold in 1983. If the rear brake isn't returning, you may have to remove the brake pedal and clean the metal shaft and inside of the pedal that inserts onto the shaft. Really not a great place to grease or lube as this attracts grit and dirt. Ensure the return spring is installed properly as it is fairly stout and will generally return the pedal even if the shaft and pedal are gritty. Is the rear brake a disk or drum? If it is a drum, some cleaning there may be needed.

I would spray the brake pedal shaft with Liquid wrench penetrating spray lubricant & let it sit overnight. then spray some more & try to work it free. Then do as wiredgeorge says & take it apart for a good cleaning. I would grease the shaft with brake caliper lubricant as the stuff pretty much stays put, repels water & doesn't attract dirt & grit. You don't need to gob it on. just use a small amount & wipe off any excess. I use Permatex ultra disk brake lube in the little packets.

Whatever it is, he should refurbish the entire brake, even if the problem is the brake pedal shaft.

Drum brake --- Rear brake shoes. For a drum brake, If you don't know the age of the rear brake shoes, replace them. The adhesive that binds the linings to the shoes can fail over time, so a lining can separate from a shoe, then get jammed between the shoe & drum, locking the rear wheel. It happened to me when rolling the bike of the center stand, so it does happen. I was lucky that it happened in the driveway. It would be a real drag for the rear wheel to lock at speed & far from home. But I'm guessing the op has a rear disk brake which could have other potential problems.
