How to Bleed the Brakes on Your 2019 Yamaha XSR700
Shop parts for a 2019 Yamaha XSR700 Motorcycle.The 2019 Yamaha XSR700 pairs its lively parallel twin with hydraulic disc brakes front and rear with ABS. The front brake is fed by the master cylinder and reservoir on the right handlebar, and the rear brake is fed by a separate master cylinder operated by the foot pedal with its own reservoir. Each circuit has a bleeder on its caliper and is bled on its own.
Why Fresh Fluid Matters
Brake fluid pulls moisture from the air over time. As the water content rises, the fluid’s boiling point drops. Hard stops can heat old fluid enough to form vapor bubbles, and vapor compresses where fluid does not. The result is a soft lever and brakes that fade. Moisture also promotes corrosion inside calipers and master cylinders.
- A spongy or inconsistent front lever
- A rear pedal that feels soft or travels farther than normal
- Dark, murky fluid visible in a reservoir
- Recent work that opened the system
What You’ll Need
- 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 sized to fit snugly over the bleeder
- A catch bottle
- A syringe or turkey baster
- A screwdriver or driver for the reservoir caps
- Rags, shop towels, and water
Setting Up
Park the bike on a paddock stand or other secure stand so it can’t tip. Turn the handlebars until the front reservoir sits level. Drape rags over the tank, headlight, and instruments. Brake fluid can damage paint and plastic, so wipe drips right away and rinse with water. Clean around the reservoir caps so dirt can’t fall in.
Step-by-Step Bleeding
- Remove the front reservoir cap and diaphragm.
- Use the syringe to remove most of the old fluid without letting the reservoir run dry.
- Refill the reservoir with fresh fluid.
- Fit the clear tube over the bleeder of the front caliper farthest from the master cylinder and route the other end into the catch bottle.
- Squeeze the lever and hold it.
- Open the bleeder about a quarter turn.
- Close the bleeder before letting go of the lever.
- Repeat, topping off the reservoir every few strokes.
- Stop when clean, bubble-free fluid flows through the tube, then close the bleeder.
- Bleed the second front caliper, if your bike has one.
- Bleed the rear caliper using the foot pedal and rear reservoir.
ABS Caution
On an ABS bike, the most important habit is never letting a reservoir run low. If air gets drawn into the master cylinder, it can work its way into the ABS unit, and a standard bleed at the calipers may not remove it. Check the level constantly and keep your strokes smooth and full.
Helpful Tips
- Tap the caliper and lines lightly to free trapped bubbles.
- Close the bleeder snugly; overtightening can damage it.
- Never reuse fluid from the catch bottle.
- Keep the fluid container sealed when not pouring.
Wrapping Up
Fill each reservoir to the proper level, reinstall the diaphragms and caps, and clean away any spilled fluid. Check the bleeders and fittings for leaks and dispose of the old fluid properly. Both controls should feel firm and should not sink under steady pressure. Spin each wheel to make sure nothing drags, then test the brakes at low speed in a safe area before heading out.
When a Shop Is the Better Call
If a reservoir ran dry or the ABS unit or its lines were disconnected, air may have entered the ABS unit, and the system may require a dealer-level procedure or diagnostic tool. A lever that only firms up after pumping, constant bubbles, or a leaking master cylinder or caliper also call for a professional inspection.
