How to Flush and Bleed the Brakes on a 2020 Ducati Multistrada 1260 S

The 2020 Ducati Multistrada 1260 S has hydraulic disc brakes at both wheels and is ABS-equipped. The front lever and rear pedal each operate a sealed hydraulic circuit, so a proper bleed removes old fluid and trapped air from those circuits. This article covers a conventional caliper-level bleed: refreshing fluid and purging air that entered through normal service, a low reservoir, or work on a caliper or line. It does not cover internal ABS bleeding. If the ABS unit itself has air in it—for example, because the reservoir ran dry or the ABS unit or its lines were disconnected—the bike may need a dealer-level procedure or diagnostic tool, and that portion should go to a shop.
Symptoms That Call for a Bleed
A spongy or soft lever, a lever that pulls closer to the grip than it used to, or a rear pedal that feels vague are the classic signs of air in the system. Dark or cloudy fluid in the reservoir is another reason to flush. Bleeding is also required after any work that opened the hydraulic system, such as new lines, caliper service, or master cylinder work. Even without symptoms, brake fluid absorbs moisture over time, which lowers its boiling point and can contribute to brake fade under hard use, so many riders refresh it on a regular schedule.
Tools and Supplies to Gather
- 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
- Clear tubing that fits snugly over the bleeder
- A catch bottle for used 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 when working alone, but the manual lever-and-bleeder method below works with basic tools. Do not reuse fluid that has been bled out.
Preparation Before Opening the System
Support the bike securely upright on a stand. 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. Wipe up any spill immediately and rinse the area with water. Work in a well-ventilated space, keep the fluid container closed when not in use, and leave the reservoir cap off only while you are actively working.
Step-by-Step Bleeding Procedure
- Open the reservoir and use the syringe or turkey baster to remove most of the old fluid. Do not let the reservoir run dry.
- Refill with fresh fluid from the sealed container, leaving room to watch the level as you work.
- Attach the clear tubing to the bleeder valve and route the other end into the catch bottle. Keep the bottle lower than the bleeder.
- Squeeze and hold the front lever, or press and hold the rear pedal. Do not release it yet.
- Open the bleeder about a quarter turn to let fluid and air escape. Watch the tubing for bubbles and dirty fluid.
- Close the bleeder before releasing the lever or pedal. Releasing first can draw air back into the system.
- Repeat the squeeze-hold-open-close-release cycle until fresh, clean, bubble-free fluid comes through the tube. Keep topping off the reservoir throughout so it never runs low enough to draw air in.
- If your bike has two front calipers, bleed each one in turn. As a general rule, start with the caliper farthest from the master cylinder if the layout gives a clear farthest point; on many front systems the two are similar, so finish one completely before moving to the other.
- Move to the rear brake and repeat the same process at its bleeder, using the pedal instead of the lever. The rear circuit has its own reservoir, so check and top it off separately.
Finishing the Job
Tighten the bleeder snugly without overtightening. Fill the reservoir to the correct level marking, wipe the cap area clean, and reinstall the diaphragm and cap. Clean any spilled fluid and check for leaks at the bleeder and at the banjo fittings. Pump the lever and pedal a few times to confirm they build pressure normally.
Test Before Riding
The lever and pedal should feel firm and consistent, not spongy, and 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 anything feels inconsistent, stop and recheck the bleed before heading out.
Troubleshooting and When to See a Shop
If the lever will not firm up after several bleeding attempts, if it firms only after pumping, if bubbles keep appearing, or if fluid leaks from the master cylinder or caliper, stop and diagnose the cause. Air that has entered an ABS unit, or a bike with a linked system and additional bleed points, may require a dealer-level procedure or diagnostic tool. When in doubt, have a professional inspect the system rather than riding with uncertain brakes.
