Bleeding the Brakes on a 2000 Triumph TT 600
Shop parts for a 2000 Triumph TT 600 Motorcycle.The 2000 Triumph TT 600 was Triumph’s four-cylinder supersport, and it stops with hydraulic disc brakes front and rear without ABS. The front brake is fed by the master cylinder and reservoir on the right clip-on, and the rear brake by a separate master cylinder operated by the foot pedal, with its own reservoir. Each circuit ends at a bleeder on its caliper and is bled independently. On a sport bike that may see hard braking on fast roads or track days, fresh fluid is essential, and on a bike of this age it is often overdue.
Why a Sport Bike Needs Fresh Fluid
Brake fluid absorbs moisture over time, lowering its boiling point. Repeated hard stops from speed generate a lot of heat, and old fluid can boil, forming vapor that compresses and causes a soft lever and fade. On an older bike, moisture can also encourage corrosion inside calipers and master cylinders. Many riders refresh the fluid on a regular schedule for those reasons.
Bleed soon if:
- The lever feels spongy or pulls closer to the grip than it used to
- The rear pedal feels soft or sinks
- The fluid in a reservoir looks dark or cloudy
- The system was opened for new lines, caliper service, or master cylinder repair
Tools and 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 snugly over the bleeder
- A catch bottle
- A syringe or turkey baster
- A screwdriver or driver for the reservoir caps
- Rags or shop towels
A one-way check-valve bleeder or vacuum bleeder lets you do the job without a helper.
Preparing the TT 600
Support the bike securely upright on a paddock stand. Turn the handlebars until the front reservoir is level. Cover the tank, fairing, and instruments with rags. Sport bike bodywork sits close to the reservoirs, and most brake fluids damage paint and plastic on contact, so protect it well and wipe up any spill immediately, rinsing with water. Make sure the bleeders will turn before you begin; use a box-end wrench with steady pressure.
Bleeding Steps
- Remove the front reservoir cap and diaphragm.
- Draw out most of the old fluid with the syringe, keeping the reservoir from running dry.
- Refill with fresh fluid.
- Attach the clear tube to 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 to let fluid and air escape.
- Close the bleeder before releasing the lever.
- Repeat, topping off the reservoir every few strokes so it never runs low enough to draw in air.
- When fresh, clean, bubble-free fluid comes through, close the bleeder.
- Bleed the second front caliper, if your bike has one.
- Bleed the rear caliper using the foot pedal and rear reservoir.
Expect the first fluid out of an older system to be dark. Keep going until it runs clean.
Finishing and Testing
Tighten each bleeder snugly without overtightening. Fill the reservoirs to the correct level marks, reinstall the diaphragms and caps, and clean away any spilled fluid. Check the bleeders and banjo fittings for leaks, and look over the brake hoses for cracks or swelling. Dispose of the old fluid properly.
The lever and pedal should feel firm and consistent and should not slowly sink under steady pressure. Spin both wheels to confirm the brakes are not dragging. Test the brakes at low speed in a safe area before riding normally.
When to See a Shop
Have the bike inspected if the lever will not firm up after several attempts, only firms up after pumping, keeps producing bubbles, or if fluid leaks from a master cylinder or caliper. On a bike of this age, those symptoms can point to worn master cylinder seals, sticky caliper pistons, or aging hoses.
