What This CBR1000RR Brake System Includes
The 2016 Honda CBR1000RR uses hydraulic disc brakes at both ends, so the front lever and the rear pedal each act on fluid-filled calipers. That means both circuits can be bled at the caliper bleeders when you are refreshing fluid or chasing a spongy feel. Some versions of this model family were offered with ABS or combined braking hardware, and those systems add hardware such as an ABS modulator and additional lines. A routine fluid refresh through the caliper bleeders is still the normal starting point, but if the reservoir has run dry, the ABS unit or its lines have been disconnected, or you are unsure whether your bike has a combined system with extra bleed points, do not experiment with the modulator. Have a shop handle that part of the job.
When a Bleed Is Due
Bleeding is due when the front lever feels soft or spongy, when it pulls closer to the grip than it used to, when the rear pedal feels vague, or when the fluid in either reservoir looks dark or cloudy. It is also due after any work that opened the hydraulic system, such as new brake lines, caliper service, or master cylinder work. Even without symptoms, brake fluid absorbs moisture over time, which lowers its boiling point and can contribute to brake fade under hard use. Many riders refresh the fluid on a regular schedule for that reason alone. If you see fluid weeping at a banjo fitting or bleeder, fix the leak before you bleed; otherwise you will keep drawing air into the system.
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 used fluid
- Rags or shop towels, plus 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 work easier
Use clear tubing so you can see bubbles and color changes. Keep the catch bottle below the caliper so gravity helps, and do not reuse fluid that has passed through the system.
Preparation Before You Open the Hydraulic System
Support the CBR1000RR securely upright on a stand. Turn the handlebars so the front master cylinder reservoir sits level before you remove the cap; a tilted reservoir can spill fluid as soon as the cover comes off. Locate the rear master cylinder reservoir and make it level as well. Cover painted surfaces, plastics, 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. Work in a well-ventilated space and keep the reservoir cap and diaphragm clean while they are off the bike.
Step-by-Step Bleeding Procedure
- Clean the top of the reservoir, remove the cap and diaphragm, and use a syringe or baster to draw most of the old fluid out. Leave enough fluid in the reservoir that you do not push air into the master cylinder.
- Refill the reservoir with fresh fluid from the sealed container. Keep the cap nearby but do not seal the reservoir yet; you will need to top it off repeatedly.
- Start with one front caliper. Slip the clear tubing over the bleeder, route the other end into the catch bottle, and fit the box-end wrench onto the bleeder.
- Squeeze the front lever several times and hold it firmly against the grip. While you hold it, open the bleeder about a quarter turn. Fluid and any trapped air will move through the tube.
- Close the bleeder before you release the lever. Releasing with the bleeder open can draw air back into the caliper. Then release the lever slowly and repeat the squeeze-hold-open-close-release cycle.
- Watch the tubing. Continue until the fluid coming through is clean and free of bubbles, and keep topping off the reservoir throughout so it never runs low enough to draw air in.
- If your bike has a second front caliper, bleed it the same way after the first one is finished. In general, start with the caliper farthest from the master cylinder, then move to the closer one.
- Move to the rear hydraulic brake and repeat the same process with the rear pedal: press and hold, open the bleeder briefly, close it before releasing, and keep the rear reservoir topped off. Finish when the fluid is clean and bubble-free.
Finishing the Job and Checking for Leaks
When both circuits are bled, tighten each bleeder snugly without overtightening. Fill each reservoir to the correct level marking, reinstall the diaphragm and cap, and wipe away any spilled fluid. Check the bleeder valves and the banjo fittings at the master cylinders and calipers for weeping. Pump the front lever and rear pedal a few times, then inspect again. A small seep can look like a successful bleed until the lever starts to fade on the road.
Test Ride and Final Confirmation
The front lever and rear pedal should feel firm and consistent, not spongy, and they should not slowly sink while you hold 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, such as an empty lot, and make sure the bike stops smoothly with both controls. If anything feels inconsistent, stop and recheck the bleeders, fluid level, and fittings before continuing.
If the Lever Will Not Firm Up
A lever that will not firm up after several bleeding attempts, a lever that firms only after pumping, persistent bubbles, or fluid leaking from the master cylinder or caliper means the job is not finished. If your CBR1000RR has ABS or combined braking hardware and air may have entered the ABS unit, or if you are not confident about the correct sequence for a system with extra bleed points, take the bike to a shop. Do not keep opening bleeders at random hoping the air will clear; that can introduce more air and make the problem harder to diagnose.
