Bleeding the Brakes on a 2000 Honda RC51 RVT1000R
Shop parts for a 2000 Honda RC51 - RVT1000R Motorcycle.The 2000 Honda RC51 RVT1000R uses hydraulic disc brakes at both ends, with a caliper on each side of the front wheel and a hydraulic rear caliper. This bike is not equipped with ABS or a linked brake system, so the front lever and rear pedal work independently. That makes it a straightforward bleed job for a DIY rider with basic tools, provided you work methodically and never let the reservoir run dry.
Why and When the RC51 Needs a Brake Bleed
Bleeding does two jobs: it removes air from the hydraulic system and, when you flush the old fluid out, it replaces moisture-contaminated fluid with fresh fluid. A spongy lever, a pedal that feels soft or travels farther than it used to, or a lever that pulls closer to the grip are classic signs that air is in the system. Dark or cloudy fluid in the reservoir is another reason to service the brakes.
Brake fluid absorbs moisture over time, which lowers its boiling point and can lead to brake fade under hard use. Even if the RC51 still stops well, many riders refresh the fluid on a regular schedule as preventive maintenance. You should also bleed the brakes after any work that opened the hydraulic system, such as installing new lines, servicing a caliper, or repairing the master cylinder.
Tools and Supplies for the Job
- 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
- A catch bottle for 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
- Optional: a one-way check-valve bleeder or vacuum bleeder, which can make the job easier for one person
Set Up the Bike and Protect the Finish
Support the RC51 securely upright on a stand so it cannot tip while you are working the lever and pedal. 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. If a spill happens, wipe it up immediately and rinse the area with water.
Work with the bike cool and give yourself room to move around both ends. You will be going back and forth between the reservoir and the caliper, so keep the fresh fluid, rags, and catch bottle within reach. Do not open the reservoir until the bike is stable and the area is protected.
Bleeding the Front and Rear Brakes
Use this sequence on each front caliper, then repeat the same basic process on the rear caliper using the pedal. Because the RC51 has a caliper on each side of the front wheel, treat each front caliper as its own bleed point and finish one completely before moving to the other. As a general practice, start with the caliper farthest from the master cylinder if the plumbing makes one side longer; otherwise pick one side and work through it fully.
- 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 and cap later.
- Attach the clear tubing to the bleeder valve and route the other end into the catch bottle.
- Squeeze and hold the front lever, or press and hold the rear pedal, and keep pressure on it.
- Open the bleeder about a quarter turn to let fluid and air escape through the tube.
- Close the bleeder before releasing the lever or pedal. Releasing first can draw air back into the system.
- Repeat the squeeze-hold-open-close-release cycle until fresh, clean, bubble-free fluid comes through the tube.
- Keep topping off the reservoir throughout the process so it never runs low enough to draw air in.
- Repeat the sequence on the other front caliper, then on the rear caliper using the pedal.
- Check the reservoir level after each caliper and top off as needed before moving on.
Finishing Up and Testing Before You Ride
When clean fluid is coming through and no bubbles remain, tighten 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 before you put the tools away.
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 the lever or pedal still feels soft, repeat the bleed process before assuming the job is done.
Troubleshooting and When to See a Shop
If the lever will not firm up after several bleeding attempts, if it firms up only after pumping, or if you keep seeing persistent air bubbles, stop and reassess. Fluid leaking from the master cylinder or caliper is another sign that the job needs more attention than a simple bleed. Because this RC51 has no ABS unit and no linked brake system, you do not need to worry about an ABS bleed sequence or a linked-brake procedure, but a brake system that will not hold pressure should still go to a qualified shop.
If you are not confident in your results, or if you suspect a damaged line, a failing master cylinder, or a caliper seal, have the bike inspected before riding. Brakes are safety-critical, and a firm, consistent lever and pedal are the minimum standard for the job to be considered complete.
