Bleeding the Brakes on a 2016 Ducati Scrambler Sixty2
Shop parts for a 2016 Ducati Scrambler Sixty2 Motorcycle.
The 2016 Ducati Scrambler Sixty2 uses hydraulic disc brakes at both ends and is ABS-equipped. That configuration matters because the front lever and rear pedal each operate a separate hydraulic circuit, and the ABS unit sits within those circuits. A normal caliper bleed is still the right way to refresh fluid and remove air from the calipers and lines, but it does not manually purge the ABS unit itself. If the reservoir has run dry or the ABS unit or its lines have been disconnected, the bike may need a dealer-level procedure or diagnostic tool. This guide walks you through a careful front and rear bleed on the Sixty2, with checks to confirm the job is complete before you ride.
When a Bleed Is Due
Brake fluid absorbs moisture over time, which lowers its boiling point and can contribute to brake fade under hard or repeated use. Even if the brakes feel normal, many riders refresh the fluid on a regular schedule as preventive maintenance. A bleed is also due when the front lever feels spongy or soft, when it pulls closer to the grip than it used to, when the rear pedal feels vague, or when the fluid in the reservoir looks dark or cloudy. Any work that opened the hydraulic system—new lines, caliper service, or master cylinder work—also calls for a bleed once the system is closed again.
What You Need Before You Start
- Fresh brake fluid of the type marked on the master cylinder reservoir cap, from a sealed container. Do not reuse fluid that has been opened and sitting.
- A box-end wrench that fits the bleeder valve snugly.
- A length of clear tubing that fits tightly over the bleeder valve.
- A catch bottle for used fluid.
- Rags or shop towels, plus water for rinsing spills.
- A syringe or turkey baster for removing old fluid from the reservoir.
- A screwdriver or driver that fits the reservoir cap screws.
- Optional: a one-way check-valve bleeder or vacuum bleeder can make the job easier for one person.
Setting Up Safely
Support the Sixty2 securely upright on a stand so it cannot tip while you are working at the lever, pedal, and calipers. Turn the handlebars so the front reservoir sits level before you open it. Cover painted surfaces, plastic covers, 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. Keep the reservoir cap and diaphragm clean and set them aside where they will not pick up grit.
Bleeding the Front and Rear Hydraulic Systems
The front and rear are separate circuits, so complete one circuit before moving to the other. The order between front and rear is less important than finishing each circuit fully. If you are working on a variant with more than one front caliper, treat each caliper as its own bleed point and start with the caliper farthest from the master cylinder.
- Open the reservoir for the circuit you are bleeding and use the syringe or turkey baster to remove most of the old fluid. Do not let the reservoir run dry.
- Refill the reservoir with fresh fluid of the type marked on the cap, leaving room for the diaphragm.
- Attach the clear tubing to the caliper bleeder valve and route the other end into the catch bottle.
- For the front, squeeze the lever several times to build pressure, then hold it firmly. For the rear, press and hold the pedal.
- Open the bleeder about a quarter turn and let fluid and air flow out through the tube. Watch for bubbles and color change.
- Close the bleeder before releasing the lever or pedal. Releasing first can draw air back into the system.
- Repeat the squeeze-and-hold, open, close, and release cycle until fresh, clean, bubble-free fluid comes through the tube.
- Keep topping off the reservoir throughout the process so it never runs low enough to draw air in.
- Move to the other circuit and repeat the same steps with its reservoir, lever or pedal, and caliper bleeder.
- When the fluid runs clean and bubble-free at each bleeder, close the bleeder snugly without overtightening.
Closing the System and Checking Your Work
Fill each reservoir to the correct level marking, reinstall the diaphragm and cap, and clean any spilled fluid from the reservoir, caliper, and surrounding parts. Check for leaks at the bleeder valves and at the banjo fittings. A weep at a bleeder usually means it is not snug; a weep at a banjo fitting means that connection needs attention before the bike is ridden. Wipe everything dry, then operate the lever and pedal a few times and recheck for fresh fluid.
Test Ride and Final Checks
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 by hand to confirm the brakes are not dragging. Before riding normally, test the brakes at low speed in a safe area, such as an empty lot, and make sure the bike slows predictably from both the lever and the pedal. If either control feels different from before, stop and investigate rather than riding further.
Troubleshooting: When to Stop and Get Help
If the lever or pedal will not firm up after several bleeding attempts, if it firms only after pumping, or if air bubbles keep appearing at the bleeder, air is still entering or remaining in the system. Check that the tubing fits tightly and that the bleeder is closed before the lever or pedal is released. Fluid leaking from the master cylinder, caliper, or fittings also means the bike should not be ridden until the leak is corrected. If the reservoir ran dry, or if the ABS unit or its lines were disconnected, air may have entered the ABS unit itself; that is beyond a standard caliper bleed and should go to a shop with the proper procedure or diagnostic tool. When in doubt, stop and have the brake system inspected before riding.
