How to Flush and Bleed the Brakes on a 2002 Honda VFR800FI Interceptor ABS
Shop parts for a 2002 Honda VFR800FI - Interceptor ABS Motorcycle.Why and When the VFR800 ABS Brakes Need Bleeding
The 2002 Honda VFR800FI Interceptor ABS uses hydraulic disc brakes at both ends, and the ABS model adds an ABS modulator into the hydraulic circuit. A routine fluid refresh is still done through the caliper bleeders, but the ABS unit changes what you should do if air gets into the system. If the reservoir has run dry, the ABS unit or its lines have been disconnected, or you suspect air is trapped inside the modulator, stop and have the bike serviced by a shop with the correct diagnostic equipment. Do not try to force air through the ABS unit by pumping the lever.
Bleed the brakes 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, such as new lines, caliper service, or master cylinder work. Brake fluid absorbs moisture over time, which lowers its boiling point and can lead to brake fade under hard use. Many riders refresh the fluid on a regular schedule even when the brakes still feel normal.
Tools and Supplies to Have Ready
- Fresh brake fluid of the type marked on the master cylinder reservoir cap, from a sealed container. Do not substitute a different fluid type.
- A box-end wrench that fits the bleeder valve snugly.
- A length of clear tubing that fits tightly over the bleeder, plus a catch bottle.
- Rags or shop towels, and a syringe or turkey baster for removing old fluid from the reservoir.
- The correct screwdriver or driver for the reservoir cap screws.
- Optional: a one-way check-valve bleeder or vacuum bleeder can make one-person bleeding easier.
Work with the bike supported 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.
Step-by-Step Bleeding Procedure
Work on one hydraulic circuit at a time. On the front, bleed each caliper in turn; if your bike has two front calipers, do one completely and then the other. As a general practice, start with the caliper farthest from the master cylinder by hose routing. The rear brake is bled at its own caliper bleeder using the pedal.
- 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.
- Attach the clear tubing to the bleeder valve and route the other end into the catch bottle. Make sure the tubing fits snugly so air cannot be drawn in around it.
- Pump the lever or press the pedal several times to build pressure, then hold it firmly.
- Open the bleeder about a quarter turn with the box-end wrench. Fluid and air will flow through the tube.
- Close the bleeder before releasing the lever or pedal. Releasing first can draw air back into the system.
- Repeat the squeeze-and-hold, open, close, and release sequence until fresh, clean, bubble-free fluid comes through the tube.
- Keep checking the reservoir throughout and top it off before it gets low. If it runs dry, air enters the system and you will have to start over.
- Move to the other front caliper if your bike has two, then repeat the same procedure at the rear caliper using the pedal.
- When clean fluid is flowing at every bleeder, close each bleeder snugly without overtightening.
Finishing the Job and Checking Your Work
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. 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. Before riding normally, test the brakes at low speed in a safe area.
Troubleshooting and When to See a Shop
If the lever or pedal will not firm up after several bleeding attempts, if it firms up only after pumping, if you keep seeing air bubbles, or if fluid is leaking from the master cylinder or caliper, stop and diagnose the problem before riding. A lever that slowly sinks under steady pressure can indicate an internal leak or trapped air. If your bike has a linked or combined brake system, there are additional bleed points and a required sequence; do not improvise it. Any situation where air may have entered the ABS unit is also a shop-level concern. A correct bleed leaves both brakes firm, clean, and leak-free.
