How to Bleed the Brakes on a 2020 Ducati Multistrada 950 S
Shop parts for a 2020 Ducati Multistrada 950 S Motorcycle.What This Multistrada's Brake Layout Means for the Job
The 2020 Ducati Multistrada 950 S uses hydraulic disc brakes at both ends and is equipped with ABS. That means you have a conventional caliper bleeder at each brake unit and a master cylinder reservoir that must stay topped up during the job. A standard bleed at the calipers is the right approach for replacing old fluid and removing air that has collected in the lines or calipers. It is not the same as servicing the ABS unit. If the reservoir has run dry, or if the ABS unit or its lines have been disconnected, air may be trapped where a hand bleed cannot reach; that situation belongs with a shop that has the correct diagnostic equipment. This article covers bleeding the front and rear hydraulic brakes; it does not cover the clutch or any mechanical adjustment.
Why and When a Bleed Is Due
Brake fluid absorbs moisture over time, even in a sealed system. Moisture lowers the fluid's boiling point, and under hard use that can lead to brake fade or a soft lever when you need the brakes most. Many riders refresh fluid on a regular schedule even when the brakes feel fine. A bleed is also due when the front lever or rear pedal feels spongy, when the lever pulls closer to the grip than it used to, when the fluid in the reservoir looks dark or cloudy, or after any work that opened the hydraulic system – new lines, caliper service, or master cylinder work. If the lever sinks slowly under steady pressure, stop riding and inspect the system before you bleed it.
Tools and Supplies to Stage First
- Fresh brake fluid of the type marked on the master cylinder reservoir cap, from a sealed container. Do not guess or substitute.
- A box-end wrench that fits the bleeder valve snugly.
- Clear tubing that fits tightly over the bleeder and reaches a catch bottle.
- A clean catch bottle for old fluid.
- Rags or shop towels, plus water for rinsing spills.
- A syringe or turkey baster for removing old fluid from the reservoir.
- The correct driver for the reservoir cap screws.
- Optional: a one-way check-valve bleeder or vacuum bleeder can make a one-person job easier.
Preparing the Bike and Protecting Surfaces
Support the Multistrada securely upright on a stand so the reservoirs sit level. For the front, turn the handlebars until the front reservoir is level before you open it. Cover the painted surfaces, plastics, and instrument area with rags, because most brake fluid damages paint and plastic on contact. If a spill happens, wipe it up immediately and rinse the area with water. Work in a well-ventilated space and keep the fresh fluid container closed when you are not pouring from it.
Bleeding the Front Brake
- Open the front reservoir and use the syringe or baster to remove most of the old fluid. Leave enough to keep the master cylinder from drawing air, then refill with fresh fluid.
- Fit the clear tube over the front caliper bleeder and route the other end into the catch bottle.
- If your bike has two front calipers, work on one caliper at a time. As a general practice, start with the caliper farthest from the master cylinder.
- Squeeze and hold the front lever. With the lever held, open the bleeder about a quarter turn and let fluid and air escape.
- Close the bleeder before you release the lever. Never release the lever with the bleeder open, or air can be drawn back in.
- Repeat squeeze, hold, open, close, and release until fresh, clean fluid runs through the tube with no bubbles. Keep watching the reservoir and top it off throughout; it must never run low enough to pull air into the system.
- When the fluid is clean and bubble-free, close the bleeder snugly without overtightening, then repeat the process on the other front caliper if equipped.
Bleeding the Rear Brake
The rear brake uses the same principle, but you operate the pedal instead of the lever. Keep the bike upright so the rear reservoir is level, open it, and remove most of the old fluid before refilling with fresh fluid. Attach the clear tube to the rear caliper bleeder and route it to the catch bottle. Press and hold the pedal, open the bleeder about a quarter turn, then close it before releasing the pedal. Repeat until clean, bubble-free fluid comes through. Keep the reservoir topped off after every few strokes. Finish by closing the bleeder snugly without overtightening.
Finishing, Testing, and When to Stop
Fill the reservoir to the correct level marking, reinstall the diaphragm and cap, and clean any spilled fluid from the bike. Check the bleeder and the banjo fittings for leaks. Before riding, the front lever and rear pedal should feel firm and consistent, not spongy, and neither should slowly sink under steady pressure. Spin each wheel to confirm the brakes are not dragging. Test at low speed in a safe area before riding normally. If the lever will not firm up after several attempts, if it firms only after pumping, if bubbles keep appearing, or if fluid leaks from the master cylinder or caliper, stop and have the bike inspected. Because this Multistrada has ABS, any sign that air entered the ABS unit – especially after a reservoir ran dry or lines were disconnected – is a shop-level job rather than a continued driveway bleed.
