How To Bleed 2010 Triumph Daytona 675 Motorcycle Brakes

How to Bleed the Brakes on a 2010 Triumph Daytona 675

The 2010 Triumph Daytona 675 uses hydraulic disc brakes at both ends, with a conventional system rather than ABS or linked braking. That makes it a good candidate for a home bleed: you are refreshing fluid and removing air at the calipers and master cylinder, not servicing an electronic pressure module. Because brakes are safety-critical, work methodically and stop if anything feels unclear.

Why and When a Bleed Is Due

A spongy or soft lever, a lever that now pulls closer to the grip than it used to, or a pedal that feels vague are the classic signs that air or old fluid is affecting the 2010 Daytona 675’s hydraulic system. Dark or cloudy fluid in the reservoir is another prompt. So is any recent work that opened the hydraulic circuit, 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.

Tools and Supplies to Have Ready

• 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
• A syringe or turkey baster for removing old fluid from the reservoir
• A screwdriver or driver that fits the reservoir cap screws

A one-way check-valve bleeder or a vacuum bleeder can make the job easier for one person, but the basic lever-and-bleeder method works fine with a helper or with careful solo technique.

Preparation and Paint Protection

Support the bike securely upright on a stand so the reservoirs sit as level as possible. Turn the handlebars so the front reservoir is 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 fluid spills, wipe it up immediately and rinse the area with water. Keep the reservoir cap and diaphragm clean and set them aside where they will not pick up grit.

Draining the Old Fluid and Filling Fresh

Open the reservoir and remove most of the old fluid with a syringe or turkey baster, but do not let the reservoir run dry. Refill with fresh fluid from a sealed container, using the fluid type marked on the cap. Attach the clear tubing to the bleeder valve and route the other end into the catch bottle. Have the box-end wrench ready on the bleeder before you begin pumping the lever or pedal.

Bleeding the Front Brake

1. Confirm the reservoir is topped up and the clear tube is snug on the front caliper bleeder, with the free end in the catch bottle.
2. Squeeze the front lever slowly and hold it firm against the grip.
3. Open the bleeder about a quarter turn and let fluid and air escape through the tube.
4. Close the bleeder before you release the lever. Releasing with the bleeder open can draw air back into the system.
5. Release the lever slowly, then repeat the squeeze-hold-open-close-release sequence.
6. Keep checking the reservoir and top it off throughout the job so it never runs low enough to draw air in.
7. Continue until fresh, clean, bubble-free fluid comes through the tube.

If your bike has more than one front caliper, bleed each one in turn, working one caliper at a time. As a general practice, start with the caliper farthest from the master cylinder and finish with the closest one.

Bleeding the Rear Brake

1. Check that the rear reservoir is filled to a safe working level and that the tube is fitted to the rear caliper bleeder.
2. Press and hold the rear brake pedal firmly.
3. Open the bleeder about a quarter turn to release fluid and air.
4. Close the bleeder before releasing the pedal.
5. Release the pedal slowly and repeat until the fluid runs clean and free of bubbles.
6. Top off the rear reservoir as needed during the process.

Finishing the Job

When both brakes are bled, 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 a few firm lever and pedal applications is a good sign that the system is sealed.

Test Before You Ride

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. If anything feels inconsistent, do not ride the bike until the issue is resolved.

When to Stop and See a Shop

A lever or pedal that will not firm up after several bleeding attempts, a lever that firms only after pumping, persistent air bubbles, or fluid leaking from the master cylinder or caliper are reasons to stop and have the system inspected. Because this Daytona 675 does not use ABS or linked brakes, a normal bleed does not require a diagnostic tool, but any hydraulic brake problem that you cannot resolve with careful bleeding should go to a qualified shop.
