2008 Honda CBR1000RR Brake Bleeding Guide
Shop parts for a 2008 Honda CBR1000RR Motorcycle.The 2008 Honda CBR1000RR was an all-new, lighter Fireblade with radial-mount twin front calipers and a single rear disc. The front calipers are fed by a master cylinder and reservoir on the right handlebar, and the rear caliper has its own master cylinder and reservoir, operated by the foot pedal. This model has no ABS, so bleeding is a conventional job you can handle at home.
Why Bleed Your Fireblade’s Brakes?
Brake fluid absorbs moisture over time, which lowers its boiling point. A superbike’s brakes build heat fast, and old fluid can boil under hard use, creating vapor that compresses and leaves the lever soft or fading. Moisture also causes corrosion inside the calipers and master cylinders.
- The lever feels soft or comes closer to the grip
- The lever feel changes as the brakes get hot
- Fluid looks dark or cloudy
- Lines, pads, or calipers were recently serviced
Gather Your Supplies
- 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 valves
- Clear tubing that fits tightly over the bleeder
- A catch bottle
- A syringe or turkey baster
- A screwdriver or driver for the reservoir caps
- Shop rags
Set Up the Bike
Support the bike on front and rear stands so it’s upright and stable. Turn the bars to level the front reservoir. Cover the tank and fairing, because brake fluid damages paint and plastic. Keep water handy and rinse spills right away. Wipe the reservoir caps clean before opening them.
Bleeding Step by Step
- Remove the front reservoir cap and diaphragm.
- Draw out most of the old fluid with the syringe, keeping some in the bottom.
- Refill with fresh fluid.
- Fit the clear tube over the bleeder of the front caliper farthest from the master cylinder, with the free end in the catch bottle.
- Squeeze and hold the lever.
- Open the bleeder about a quarter turn.
- Close the bleeder before releasing the lever.
- Repeat, topping off the reservoir every few strokes.
- Once fresh, bubble-free fluid flows, close the bleeder.
- Bleed the second front caliper the same way.
- Move to the rear caliper and repeat using the foot pedal and rear reservoir.
Tips for a Firm Lever
- Never let either reservoir run dry, or you’ll draw air into the master cylinder.
- Tap the calipers and lines lightly to free trapped bubbles.
- Keep fluid off the discs and pads.
- Discard the fluid you collect.
Inspect While You’re There
With the brakes in front of you, check pad thickness, look at the discs for scoring or heat marks, and inspect the hoses and banjo fittings for seepage. Catching wear now saves a second trip into the system later.
Finishing Up
Tighten the bleeders snugly, fill both reservoirs to their correct level marks, and reinstall the diaphragms and caps. Clean up all fluid, check for leaks, and dispose of the old fluid properly. The lever and pedal should feel firm without slowly sinking. Spin both wheels to check for drag, then test the brakes at low speed in a safe area before riding normally.
When to Call a Pro
If the lever won’t firm up, only improves after pumping, or a caliper or master cylinder leaks, have a qualified technician inspect the brakes before you ride.
