To adjust the rear brakes on a Harley-Davidson motorcycle, you can follow these general steps:
Preparation: Ensure the motorcycle is securely supported on a stable surface, and the rear wheel is off the ground. You may use a motorcycle lift or a sturdy jack to lift the rear wheel.
Accessing the Brake Caliper: Locate the rear brake caliper, which is typically mounted on the rear swingarm or the rear axle. It is usually held in place by bolts or pins. Remove any necessary hardware to gain access to the caliper.
Inspect the Brake Pads: Before making any adjustments, visually inspect the brake pads. Ensure they have enough pad material remaining and that they are wearing evenly. If the pads are worn beyond their service limit or show signs of uneven wear, they may need replacement.
Adjusting the Brake Caliper: Most Harley-Davidson motorcycles use a single-piston caliper with an adjuster screw. The adjuster screw is located on the backside of the caliper and usually has a locking nut. Loosen the locking nut and turn the adjuster screw clockwise or counterclockwise to adjust the brake pad clearance. The goal is to achieve a slight drag on the rotor when the wheel is turned.
Tightening the Adjuster Screw: Once the desired brake pad clearance is achieved, hold the adjuster screw in place and tighten the locking nut to secure the adjustment.
Reassembly and Testing: Reinstall any hardware that was removed to access the caliper. Lower the motorcycle, and check the rear brake operation. Gently squeeze the brake pedal to ensure proper braking action and verify that the rear wheel rotates freely without excessive drag.
It's important to note that specific models and model years of Harley-Davidson motorcycles may have slight variations in their brake systems. Therefore, it is always recommended to refer to the owner's manual or consult a qualified technician for the precise instructions and specifications for your particular motorcycle.
