Bleeding the Brakes on a 2025 Ducati Multistrada V2

What This Job Covers on the Multistrada V2

The 2025 Ducati Multistrada V2 uses hydraulic disc brakes at both ends, and ABS is part of the system. The front lever and the rear pedal operate separate hydraulic circuits, so you will bleed them one at a time. This guide covers a fluid flush and air removal through the caliper bleeders. It does not cover pad or rotor replacement, and it does not cover a hydraulic clutch. If the bike has recently had brake lines, calipers, or a master cylinder opened, or if the lever or pedal has gone soft, this is the job to complete before normal riding resumes.

When a Bleed Is Due

A spongy lever or pedal is the clearest sign that air or old fluid is affecting the system. So is a lever that now pulls closer to the grip than it used to, or a pedal that feels longer before it bites. Look at the fluid in the reservoir: dark, cloudy, or contaminated fluid is past its useful life. Any time the hydraulic system has been opened for line replacement, caliper service, or master cylinder work, air can enter and a bleed is required afterward.

Brake fluid also absorbs moisture over time, even in a sealed system. That moisture lowers the fluid’s boiling point, which can lead to brake fade under hard or repeated use. Many riders refresh the fluid on a regular schedule even when the brakes still feel acceptable, because the change is gradual and easy to miss from the saddle.

Tools and Supplies to Stage First

  • Fresh brake fluid of the type printed 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
  • Optional: a one-way check-valve bleeder or vacuum bleeder to make one-person work easier

Preparing the Bike and Protecting Surfaces

Support the Multistrada V2 securely upright on a stand so the reservoirs sit level. Turn the handlebars until the front reservoir is as level as possible before you open it. Cover painted bodywork, plastic panels, and the instrument area with rags, because most brake fluids damage paint and plastic on contact. If a spill happens, wipe it up immediately and rinse the area with water. Keep the catch bottle below the caliper so fluid runs away from the bleeder rather than back toward it.

Bleeding the Front Brake

The front system on the Multistrada V2 uses more than one caliper, so bleed one caliper at a time and then move to the other. As a general practice, start with the caliper farthest from the master cylinder. Work slowly and keep the reservoir from running dry at any point.

  1. Remove the front reservoir cap and diaphragm. Use the syringe or turkey baster to remove most of the old fluid from the reservoir without letting the level drop low enough to draw air into the master cylinder.
  2. Refill the reservoir with fresh fluid from the sealed container, using the fluid type marked on the cap.
  3. Attach the clear tubing to the bleeder on the first front caliper and route the other end into the catch bottle.
  4. Squeeze the front lever slowly and hold it against the grip.
  5. Open the bleeder about a quarter turn and let fluid and air escape through the tube.
  6. Close the bleeder before you release the lever. Releasing the lever with the bleeder open can pull air back into the system.
  7. Release the lever, then repeat the squeeze-hold-open-close sequence. Check the reservoir level often and top it off so it never runs low.
  8. Continue until fresh, clean fluid with no bubbles comes through the tube. Then repeat the same process on the other front caliper.
  9. When both front calipers are done, top the reservoir to the correct level marking, reinstall the diaphragm and cap, and wipe away any spilled fluid.

Bleeding the Rear Brake

The rear circuit is bled in the same basic way, but you use the pedal instead of the lever. Keep the bike upright and the rear reservoir level before opening it.

  1. Open the rear reservoir, remove most of the old fluid, and refill with fresh fluid of the type marked on the cap.
  2. Fit the clear tubing over the rear caliper bleeder and route it into the catch bottle.
  3. Press the rear pedal slowly and hold it down.
  4. Open the bleeder about a quarter turn and let fluid and air out.
  5. Close the bleeder before releasing the pedal.
  6. Release the pedal and repeat, topping off the reservoir as needed, until the fluid runs clean and bubble-free.
  7. Top off the rear reservoir to the correct level, reinstall the diaphragm and cap, and clean any spills.

Finishing, Testing, and Knowing When to Stop

Tighten each bleeder snugly without overtightening. Fill the reservoirs to the correct level marking, reinstall the diaphragms and caps, and check for leaks at the bleeder and at the banjo fittings. Clean any fluid from painted or plastic surfaces immediately.

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 the lever or pedal 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 a caliper, stop and have the bike inspected. ABS adds another consideration: a normal caliper bleed is fine for routine fluid refresh, but if the reservoir ran dry, a line was disconnected, or the ABS unit was serviced, air may be trapped in the ABS unit itself. That may require a dealer-level procedure or diagnostic tool, so take the bike to a shop rather than continuing to pump the lever at home.
