Bleeding the Brakes on Your 2010 Ducati Streetfighter
Shop parts for a 2010 Ducati Streetfighter Motorcycle.What the 2010 Streetfighter Brake System Looks Like
The 2010 Ducati Streetfighter uses hydraulic disc brakes at both ends, with a hand lever operating the front circuit and a foot pedal operating the rear. The front and rear are separate hydraulic systems, so each must be bled on its own. This is a conventional setup: you service it at the caliper bleeders, and there is no linked-brake sequence to follow. If your bike has two front calipers, treat them as two bleed points on the same front circuit and bleed each one in turn. The rear brake is also hydraulic, so it gets the same basic treatment as the front, just with the pedal providing the pressure.
When a Bleed Is Due
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 that air or old fluid is affecting the 2010 Streetfighter’s brake system. Dark or cloudy fluid in the reservoir is another clear indicator. You should also bleed the brakes after any work that opened the hydraulic system, such as installing new brake lines, servicing a caliper, or repairing the master cylinder. Even without symptoms, brake fluid absorbs moisture over time, which lowers its boiling point and can lead to brake fade under hard use, so many riders refresh it on a regular schedule.
Tools and Supplies to Stage First
- 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
- A length of clear tubing that fits snugly over the bleeder
- A catch bottle for the old 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 for one person, but the manual lever-and-bleeder method works fine if you have a helper or a way to hold pressure while you open the valve.
Preparing the Bike and Protecting Surfaces
Support the 2010 Streetfighter securely upright on a stand so it cannot tip while you are working. 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. Remove the reservoir cap and diaphragm, then use the syringe or turkey baster to draw most of the old fluid out of the reservoir without letting it run dry.
Step-by-Step: Bleeding the Front and Rear Brakes
- With the bike secure and the reservoir level, remove the cap and diaphragm. Draw most of the old fluid from the reservoir, but leave enough to cover the outlet so you do not pull air into the master cylinder.
- Fill the reservoir with fresh fluid of the type marked on the cap, from a sealed container. Keep the cap and diaphragm nearby, but do not leave the reservoir open longer than necessary.
- Fit the box-end wrench onto the bleeder valve. Push the clear tubing over the bleeder and route it into the catch bottle, with the tube sloping upward away from the bleeder so bubbles can escape.
- For the front brake, squeeze the lever and hold it. For the rear brake, press the pedal and hold it. Do not pump repeatedly while the bleeder is open.
- Open the bleeder about a quarter turn and let fluid and air move out through the tube. Watch the tube for bubbles.
- Close the bleeder before you release the lever or pedal. This prevents air from being drawn back into the caliper.
- Release the lever or pedal, check the reservoir level, and top it off. Repeat the squeeze-hold-open-close-release sequence 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 one at a time. A general practice is to start with the caliper farthest from the master cylinder, then move to the other. For the rear, use the same sequence at the rear caliper bleeder.
Finishing the Job and Checking Your Work
Once clean fluid is coming through at each bleeder, close the 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 and at the banjo fittings. A dry fitting after a few lever or pedal applications is a good sign; a weeping fitting needs attention before you ride.
Testing Before You Ride
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. If anything feels soft, inconsistent, or weaker than before, do not ride the bike until you find the cause.
Troubleshooting and When to See a Shop
If the lever or pedal will not firm up after several careful bleeding attempts, if it firms up only after pumping, if you keep seeing persistent air bubbles, or if fluid is leaking from the master cylinder or caliper, stop and have a shop inspect the system. The same applies if the reservoir ran dry while the system was open, or if the bike has an ABS unit that was disturbed—those cases can require dealer-level equipment to purge air properly. A brake system that will not hold a firm feel is not something to test on the road.
