Bleeding the Brakes on a 2006 Honda VFR800FI Interceptor ABS
Shop parts for a 2006 Honda VFR800FI - Interceptor ABS Motorcycle.What This VFR800 Brake Service Covers
The 2006 Honda VFR800FI Interceptor ABS is a hydraulic-disc-brake motorcycle at both ends, and the ABS designation is part of the model identity. That means this job covers the front hydraulic circuit and the rear hydraulic circuit: flushing out old fluid and removing trapped air so the lever and pedal feel firm and consistent. It does not cover replacing pads, rotors, calipers, or brake lines, although a bleed is often the final step after any of that work has opened the hydraulic system.
Because this VFR is ABS-equipped, a normal bleed through the caliper bleeders is generally the right approach for routine fluid refresh and for air that has entered the lines or calipers. The important exception is air inside the ABS unit itself. If the reservoir has run dry, the ABS unit or its lines have been disconnected, or you have reason to believe air has traveled into the ABS hardware, the motorcycle should go to a shop. That level of bleeding can require a dealer-level procedure or diagnostic tool, and it is not something to improvise in a home garage.
Signs That the Brakes Need Bleeding
A spongy or soft front lever is the classic clue, and so is a lever that now pulls closer to the grip than it used to. On the rear, a pedal that feels mushy or travels farther than normal deserves attention. Dark or cloudy fluid in the reservoir is another sign that the fluid has been in service long enough to be refreshed. You should also bleed the brakes 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 contribute to brake fade under hard or repeated use. That is why many riders refresh the fluid on a regular schedule even when the brakes still feel acceptable. A lever that slowly sinks under steady pressure is not a normal condition, and it should be investigated before the bike is ridden normally.
Tools and Supplies to Gather
- 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 valve
- A catch bottle for the old fluid
- Rags or shop towels, plus water for rinsing spills
- 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 bleeding easier
Use only fresh fluid from a sealed container, and do not reuse fluid that has been sitting open or drained out of the system. Keep the reservoir area clean before you open it so dirt does not fall into the fluid.
Preparation Before Opening the Hydraulic System
Support the motorcycle 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 remove the cap. 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.
Before you start, locate the bleeder valve on each caliper you plan to bleed and confirm that your box-end wrench fits it properly. A snug-fitting wrench reduces the chance of rounding the bleeder. Also check that the reservoir cap and diaphragm are clean before removal, and have your catch bottle positioned so the clear tubing can run downhill without kinks.
Step-by-Step Bleeding Procedure
- Remove the reservoir cap and diaphragm. Use a syringe or turkey baster to remove most of the old fluid from the reservoir, but do not let the reservoir run dry. Refill with fresh fluid to the level marking.
- Attach the clear tubing to the bleeder valve and route the other end into the catch bottle. Position the box-end wrench on the bleeder so you can open and close it smoothly.
- For the front brake, squeeze the lever and hold it. Open the bleeder about a quarter turn to let fluid and air escape, then close the bleeder before releasing the lever. Repeat this squeeze-hold-open-close-release cycle while keeping the reservoir topped off. If your bike has two front calipers, bleed one caliper at a time; as a general practice, start with the caliper farthest from the master cylinder.
- For the rear brake, press and hold the pedal, open the bleeder about a quarter turn, then close it before releasing the pedal. Repeat until the fluid runs clean and bubble-free, topping off the reservoir throughout.
- Continue bleeding each circuit until fresh, clean fluid comes through the tubing with no visible air bubbles. Check the lever and pedal feel as you go, and never let the reservoir get low enough to draw air back into the system.
Finishing Up and Checking for Leaks
When the fluid runs clean and the lever and pedal feel firm, tighten 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. A dry fitting after several lever or pedal applications is a good sign; a weep or wet spot means you need to stop and correct it before riding.
Testing Before Normal 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, and make sure the bike stops smoothly and straight. If anything feels inconsistent, do not ride the motorcycle until the problem is resolved.
Troubleshooting and When to See a Shop
If the lever will not firm up after several bleeding attempts, if it firms only after pumping, if air bubbles keep appearing, or if fluid is leaking from the master cylinder or a caliper, stop and have the system inspected. The same applies if you suspect air has entered the ABS unit, or if your VFR800 ABS has additional bleed points for a combined braking system and you are not confident about the required sequence. A brake system that will not hold a firm lever is a safety issue, and a shop with the correct ABS-level equipment is the right call.
