How To Bleed 2016 Ducati Scrambler Icon Motorcycle Brakes

How to Bleed the Brakes on a 2016 Ducati Scrambler Icon

The 2016 Ducati Scrambler Icon uses hydraulic disc brakes at both ends, and this model is equipped with ABS. Routine bleeding is still done at the caliper bleeders, just as on a non-ABS hydraulic system, while the ABS unit itself is left alone. If air has entered the ABS unit—for example, because the reservoir ran dry or a line was disconnected—the bike needs a dealer-level procedure or diagnostic tool. This guide covers a normal fluid flush and air bleed for the front and rear brakes on the Scrambler Icon.

When the Scrambler Icon Needs a Bleed

A spongy or soft front lever, a rear pedal that feels vague, or a lever that pulls closer to the grip than it used to are all signs that air or old fluid is affecting the system. Dark or cloudy fluid in either reservoir is another clue. Bleeding is also due after any work that opened the hydraulic system, such as new brake lines, caliper service, or master cylinder work. Brake fluid absorbs moisture over time, which lowers its boiling point and can lead to brake fade under hard use, so many riders refresh it on a regular schedule even when the brakes still feel normal. If the lever or pedal is already soft, bleed the brakes before riding normally.

Tools and Supplies for the Job

• Fresh brake fluid of the type marked on the master cylinder reservoir cap, from a sealed container
• A box-end wrench that fits the bleeder valve
• A length of clear tubing that fits snugly over the bleeder
• A catch bottle for old fluid
• Rags or shop towels
• A syringe or turkey baster for removing old fluid from the reservoir
• A screwdriver or driver that fits the reservoir cap screws

A one-way check-valve bleeder or a vacuum bleeder can make the job easier for one person, but the manual lever-and-bleeder method works fine if you take your time and keep the reservoir topped off.

Preparation and Paint Protection

Support the 2016 Ducati Scrambler Icon securely upright on a stand so the bike cannot tip while you are working. Turn the handlebars so the front reservoir sits level before you open it. Cover painted surfaces, plastics, and the instrument area with rags, because most brake fluids damage paint and plastic on contact. If fluid spills, wipe it up immediately and rinse the area with water. Remove the reservoir cap and diaphragm, set them on a clean rag, and keep them clean while the system is open. Do not let the reservoir run dry at any point during the job.

The Bleeding Procedure, Front and Rear

Work on the front brake first, then the rear. This Scrambler Icon uses a single front caliper; if you are ever working on a two-caliper variant, bleed each caliper separately. On a multi-caliper front end, start with the caliper farthest from the master cylinder. Treat the front and rear as separate hydraulic systems.

1. Use the syringe or turkey baster to remove most of the old fluid from the front reservoir. Leave some fluid at the bottom so you do not push air into the master cylinder. Set the old fluid aside for proper disposal.
2. Fill the front reservoir with fresh fluid from a sealed container, using the fluid type marked on the reservoir cap. Keep the diaphragm and cap nearby but do not install them yet.
3. Fit the clear tubing snugly over the front bleeder valve and route the other end into the catch bottle. Put a little fresh fluid in the catch bottle so the tube end stays submerged. Position the box-end wrench on the bleeder.
4. Squeeze the front lever slowly and hold it. Do not release the lever while the bleeder is open.
5. Open the bleeder about a quarter turn. Fluid and air will flow through the tube. Watch the tube for bubbles and for the color of the fluid.
6. Close the bleeder before you release the lever. Then release the lever slowly. This order prevents air from being drawn back into the caliper.
7. Repeat the squeeze-hold-open-close-release sequence until fresh, clean fluid comes through the tube with no bubbles. Check the reservoir often and top it off before it gets low.
8. When the front is done, close the bleeder snugly without overtightening, remove the tube, and wipe the area clean. Refill the front reservoir to the correct level marking after the final check.
9. For the rear, remove most of the old fluid from the rear reservoir, refill it with fresh fluid, and attach the clear tubing to the rear bleeder. Press and hold the rear pedal, open the bleeder about a quarter turn, then close it before releasing the pedal. Repeat until the fluid is clean and bubble-free, topping off the rear reservoir throughout.
10. Close the rear bleeder snugly without overtightening, remove the tube, and wipe the area. Do not overtighten either bleeder; snug is enough to seal it.

Finishing Up and Checking for Leaks

Fill each reservoir to the correct level marking, reinstall the diaphragm and cap, and clean any spilled fluid from the bike. Check the bleeder valves and the banjo fittings at the master cylinder and caliper for leaks. Pump the front lever and rear pedal a few times and look again for fluid at the bleeder, around the reservoir, and at the caliper. If you find a leak, stop and correct it before testing the brakes.

Test the Brakes Before Riding

The front lever and rear pedal should feel firm and consistent, not spongy, and they should not slowly sink under steady pressure. Spin each wheel to confirm the brakes are not dragging. Test the brakes at low speed in a safe area before riding normally. If either brake feels soft or inconsistent, do not ride the bike until the problem is resolved.

Troubleshooting and When to Visit a Shop

If the lever or pedal will not firm up after several bleeding attempts, if it firms up only after pumping, if bubbles keep appearing, or if fluid is leaking from the master cylinder or caliper, stop and diagnose the problem. Because this Scrambler Icon has ABS, any situation where air may have entered the ABS unit—such as a reservoir that ran dry or a disconnected line—may require a dealer-level procedure or diagnostic tool. Do not attempt to guess at an ABS bleed sequence. If you are not confident in the result, have the bike inspected by a qualified shop before riding.
