This MotoSport proprietary guide walks you through flushing and bleeding the hydraulic brakes on the 2022 Yamaha Grizzly 700Fi 4X4 EPS XT-R IRS. Follow every step carefully — clean procedures protect performance and safety on this model.

What you need

  • DOT 4 brake fluid (Yamaha recommends DOT 4 for this platform)
  • Clear vinyl hose to fit bleeder nipples
  • Brake bleeder bottle or catch container
  • 10 mm wrench (bleeder screw size may vary, check your machine)
  • Phillips or flat screwdriver for reservoir cap
  • Turkey baster or syringe for reservoir draining
  • Clean lint-free rags and isopropyl alcohol for cleanup
  • Latex gloves and eye protection
  • Assistant (recommended) or a vacuum/pressure bleeder
  • Torque wrench for caliper/restoration fasteners if removed

Important notes about the 2022 Grizzly 700Fi 4X4 EPS XT-R IRS

  • The Grizzly 700Fi uses hydraulic disc brakes front and rear with a handlebar master cylinder for the front and a foot master cylinder for the rear on certain trims. Confirm your machine's configuration before starting.
  • This model does not have antilock brakes, but it does have EPS electronics nearby; avoid spilling fluid on electrical components and EPS connectors.
  • Brake fluid will damage paint, plastic and rubber — protect bodywork and wipe spills immediately with alcohol and clean rags.
  • Brake hose routing is fixed near the IRS rear end & calf protection; inspect hoses for chafe and soft spots while working. Replace any suspect hoses before bleeding.
  • Use only DOT 4 fluid. Mixing DOT 5 (silicone) with DOT 4 will ruin the system.

Preparation

  1. Park on level ground, chock wheels, and set the parking brake. Remove key from ignition.
  2. Clean around both master cylinder reservoir caps before opening to prevent contamination.
  3. Inspect dog bones, calipers, pads and hoses for damage. Replace worn pads or leaking lines first.
  4. If using a pressure/vacuum bleeder, follow the tool manufacturer directions; otherwise, prepare an assistant for manual pump & hold method.

Step-by-step fluid replacement & bleeding

Perform the procedure for one circuit at a time. Common order: rear caliper first, then front calipers left then right (or factory sequence if specified in your manual). Use the sequence that moves from the farthest caliper from the reservoir to the closest.

  1. Remove the reservoir cap and diaphragm, then use a turkey baster to extract as much old fluid as possible. Refill to the MAX line with fresh DOT 4. Replace cap loosely so you can top during bleeding.
  2. Start with the furthest caliper from the bottle/reservoir (typically the rear caliper on Grizzly). Place clear hose on bleeder nipple and submerge the other end in a partially filled catch bottle to avoid drawing air back in.
  3. Have your assistant slowly pump the brake lever/pedal 5–10 times and hold it firmly. Open the bleeder screw approx. 1/4 turn to allow fluid and air to exit. Close screw, then instruct assistant to release the lever slowly. Repeat until fluid runs clear with no air bubbles. Always keep the reservoir topped to avoid introducing air.
  4. Torque the bleeder screw snugly (follow service torque spec if available; typically low torque around 10–15 Nm). Wipe clean.
  5. Move to the next caliper in the sequence (front left, front right or as applicable). Repeat steps 2–4 for each caliper.
  6. If the Grizzly has separate front and rear master cylinders, bleed each circuit separately and keep their reservoirs at proper levels.
  7. After bleeding all calipers, cycle the lever/pedal several times to confirm a firm feel. Re-check all bleeder screws and reservoir levels, topping to the MAX line.
  8. Clean any spilled fluid immediately. Replace reservoir caps and secure all fasteners. Test brakes at low speed in a safe area before returning to normal riding.

Using a one-man vacuum or pressure bleeder

  • Connect to the reservoir per tool instructions. Set pressure per the tool spec (typically 15–22 psi) or create vacuum at each bleeder and open bleeder screws sequentially from farthest to closest. Monitor reservoir level and don't allow it to run dry.

Troubleshooting

  • Spongy lever after bleeding: continue bleeding, check for leaks, inspect master cylinder seals and caliper pistons for damage.
  • Brake lever goes to handlebar: likely air remains or internal leak; re-bleed and inspect hoses and master cylinder.
  • Persistent leaking at bleeder screw: replace copper crush washer or bleeder screw and re-torque.

Maintenance intervals & disposal

  • Replace brake fluid every 2 years or sooner if the fluid appears dark or contaminated. Heavy use or wet conditions warrant more frequent changes.
  • Dispose of used brake fluid at an approved hazardous waste facility. Do not pour onto pavement or into drains.

Final checks specific to the Grizzly 700Fi XT-R IRS

  • After bleeding, verify the parking brake and any mechanical linkages for proper operation.
  • Inspect ABS tone rings or sensors if your variant includes them for debris; avoid spraying fluid on sensors.
  • Because the Grizzly sees demanding terrain, consider replacing brake hoses every 6–8 years or sooner if exposure to UV/abrasion is evident.

Follow these MotoSport proprietary steps and your Grizzly will maintain secure, responsive brakes. If you encounter persistent issues or internal master cylinder problems, seek professional service.
