This MotoSport guide walks you through a safe, complete brake fluid replacement and bleeding procedure specific to the 2015 Yamaha Grizzly 700 4X4. Follow each step methodically, use the correct fluid, and keep the brake reservoir topped during bleeding to avoid introducing air into the system.

What you need

  • DOT 4 brake fluid (clean, unopened container)
  • Clear plastic tubing that fits over bleed nipples
  • Catch bottle for old fluid
  • Turkey baster or fluid syringe (to remove old fluid from reservoirs)
  • Wrenches to fit bleed nipples (open wrench recommended)
  • Rubber gloves, eye protection
  • Shop rags and brake-clean spray
  • Floor jack or ramps and blocks (for safe lift/stabilize)
  • Assistant (recommended) or a vacuum/pressure bleeder

Model notes specific to the 2015 Yamaha Grizzly 700 4X4

  • The Grizzly 700 uses hydraulic disc brakes for front and rear. Use DOT 4 fluid; if your machine has a factory-installed brake system variant, confirm DOT rating on the reservoir cap and owner’s manual before starting.
  • Front master cylinder is handlebar mounted; rear master cylinder is near the frame/engine area. Identify which reservoir corresponds to which calipers before draining.
  • Some Grizzly models have EPS or accessory options that do not change the brake procedure, but if you have ABS or aftermarket components, consult MotoSport parts specialists or your service manual before proceeding.
  • Brake fluid is highly corrosive to painted surfaces and plastics. Protect bodywork and immediately clean any spills with brake-clean and water.
  • Replace rubber reservoir caps and seals if aged or cracked to prevent future contamination.

Preparation

  • Park on level ground, set parking brake, and remove key.
  • Stabilize the ATV on blocks or a jack so wheels are off the ground if you will operate calipers freely.
  • Clean around reservoir caps to prevent dirt entering the system when opened.
  • Wear gloves and eye protection; have rags ready for spills.

Procedure overview

Work one hydraulic circuit at a time (front circuit vs. rear circuit). Maintain a full reservoir while bleeding to avoid drawing air in. Use the caliper farthest from its master cylinder first, then the next farthest, finishing with the caliper closest to the master cylinder.

Step-by-step bleed and fluid replacement

  1. Remove reservoir cap(s) and diaphragm; use a turkey baster to remove most of the old fluid from reservoir(s) and dispose of it properly.
  2. Refill reservoir with fresh DOT 4 fluid to the specified level. Keep the cap loosely on to limit contamination while allowing you to monitor fluid level.
  3. Identify bleed nipple(s) on each caliper. Fit clear tubing over the nipple and route into a catch bottle partially filled with fresh fluid to avoid sucking air back into the system.
  4. If using an assistant: have them slowly squeeze the brake lever or pedal several times, then hold pressure. While pressure is held, open the bleed nipple 1/4 to 1/2 turn to allow fluid and air to escape into the tubing; close the nipple before the lever/pedal is released. Repeat pump-hold-open-close cycles until fluid runs clear with no air bubbles. Keep the reservoir topped between cycles.
  5. If using a vacuum or pressure bleeder: follow the tool manufacturer’s instructions. With a vacuum on the caliper bleed nipple, open the nipple until fluid runs clear and bubble-free, then close nipple before removing vacuum hose. If using a pressure bleeder at the reservoir, run the system until clear, but be cautious not to over-pressurize.
  6. Follow correct caliper sequence: bleed the caliper farthest from the master cylinder first, then the next farthest, finishing with the closest caliper. For the Grizzly this commonly means: rear caliper first (if rear master cylinder), then passenger-side front, then driver-side front, or whichever sequence corresponds to distance from each respective master cylinder.
  7. Periodically check and refill the reservoir so it never goes below the minimum mark. Air entry at this stage nullifies prior steps.
  8. When each caliper is clear and bubble-free, tighten bleed nipple snugly. Wipe any spilled fluid and reinstall reservoir diaphragm and cap. Do not overtighten; snug is sufficient. Confirm lever/pedal feel is firm with no sponginess.
  9. After bleeding, cycle the brakes several times under static conditions to confirm firm engagement, then conduct a low-speed test ride in a safe area to verify braking performance before normal use.

Tips, cautions & maintenance intervals

  • Replace brake fluid every two years as a best practice or sooner if fluid appears dark or contaminated.
  • Never mix DOT 3, DOT 4, and DOT 5 fluids. DOT 5 is silicone-based and incompatible with DOT 3/4 systems.
  • If you encounter persistent sponginess after thorough bleeding, inspect master cylinder seals, caliper pistons, and lines for leaks or internal contamination. Replace worn parts as needed.
  • Always torque related brake hardware to factory specs when servicing; if unsure, consult your service manual or contact MotoSport parts experts for guidance.
  • Dispose of old brake fluid according to local hazardous-waste laws; do not pour down drains.

When to seek professional service

If you find air that cannot be expelled, contaminated or leaking components, damaged reservoirs, or if your model has an unknown brake-system option (ABS/EPS variants), stop and seek professional service. MotoSport technicians and parts specialists can help identify components and supply quality replacement parts specific to your 2015 Yamaha Grizzly 700 4X4.

Performing regular brake fluid changes and careful bleeding keeps stopping power reliable and protects brake components from corrosion and premature wear – essential for safe riding on trails, work sites, and recreation runs.
