Bleeding the Hydraulic Brakes on a 2017 Ducati Multistrada 1200
Shop parts for a 2017 Ducati Multistrada 1200 Motorcycle.Why This Multistrada 1200 Needs a Proper Bleed
The 2017 Ducati Multistrada 1200 uses hydraulic disc brakes at both ends and is ABS-equipped. That means the front lever and rear pedal both push fluid through lines to calipers, and the ABS hardware is part of the hydraulic circuit. A routine bleed at the calipers is the normal way to refresh fluid and remove air from the lines and calipers. It is not a procedure for purging air from inside the ABS unit itself; if the reservoir has run dry or the ABS unit or its lines have been disconnected, the bike should go to a shop with the correct diagnostic equipment.
Bleed the brakes when the lever or 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, such as new lines, caliper service, or master cylinder work. Brake fluid absorbs moisture over time, which lowers its boiling point and can cause fade under hard use, so many riders refresh it on a regular schedule even when the brakes still feel acceptable.
Tools and Supplies to Have Ready
- 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 this job easier to do alone, but the basic lever-and-bleeder method works with a helper or with patience. Keep the fluid container closed when not pouring, and do not reuse fluid that has been through the system.
Set Up the Bike and Protect the Finish
Support the Multistrada securely upright on a stand so it cannot tip while you are working the lever or pedal. Turn the handlebars so the front reservoir sits level before you open it. Cover painted surfaces, plastic bodywork, 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 rather than letting it sit.
Clean the reservoir cap and surrounding area before opening it so dirt does not fall into the fluid. Have your catch bottle positioned before you loosen anything, and keep the reservoir cap and diaphragm clean and close at hand.
Bleeding the Front and Rear Hydraulic Systems
Work through the front first, then the rear, or follow the order that keeps the reservoir easiest to reach and top off. As a general practice, start with the caliper farthest from its master cylinder. If the front end carries more than one caliper, bleed each front caliper in turn and finish one completely before moving to the next.
- 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 the reservoir with fresh fluid of the type marked on the cap, leaving room for the diaphragm and cap to go back on later.
- Attach the clear tubing to the bleeder valve and route the other end into the catch bottle. The tubing should fit snugly so air cannot be drawn in around it.
- For the front, squeeze and hold the lever. For the rear, press and hold the pedal. Keep steady pressure on it.
- Open the bleeder about a quarter turn and let fluid and air escape through the tube. Watch the tube, not the reservoir, while the bleeder is open.
- Close the bleeder before releasing the lever or pedal. Releasing first can pull air back into the system.
- Repeat the squeeze-hold-open-close-release sequence until fresh, clean fluid comes through the tube with no bubbles.
- Keep topping off the reservoir throughout the job so it never gets low enough to draw air into the master cylinder.
- When the front is done, tighten that bleeder snugly without overtightening, then move to the rear and repeat the same sequence with the pedal.
- If the front has more than one caliper, repeat the process on the other front caliper, topping off the reservoir as needed.
Finishing, Leak Checks, and Test Ride
When the fluid coming through the tube is clean and bubble-free, close each bleeder snugly without overtightening. Fill the reservoir to the correct level marking, reinstall the diaphragm and cap, and clean any spilled fluid from the bike. Check for leaks at the bleeder valves and at the banjo fittings where the lines attach. A dry fitting after several lever or pedal applications is what you want to see.
Before riding, the lever and 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.
Troubleshooting and When to Stop
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 a caliper, stop and diagnose the problem rather than continuing to bleed. Persistent air can point to a fitting that is not sealing, a bleeder that is not closing fully, or a fluid path that is drawing air. On this ABS-equipped Multistrada 1200, any situation where air may have entered the ABS unit itself is a shop-level job. Do not attempt to guess at an ABS bleed sequence or ride a bike with a soft brake lever.
