This MotoSport guide walks you through bleeding and replacing brake fluid on a 2016 Yamaha Grizzly 700 4X4 EPS. Follow these steps carefully & use quality brake fluid to maintain safe stopping performance. Read all steps before starting and work on a cool vehicle on a level surface.

What you’ll need

  • Yamaha-recommended DOT 4 brake fluid (fresh, unopened)
  • Clear flexible bleed hose
  • Brake fluid catch container
  • Clean rags and gloves
  • 3/8" and 10 mm wrenches (verify caliper bleeder size)
  • Turkey baster or syringe (for reservoir fluid removal)
  • Brake cleaner and a small brush
  • Zip ties or clamps (to secure hoses)
  • Torque wrench for caliper bolts if you remove components

Model notes for the 2016 Yamaha Grizzly 700 4X4 EPS

  • ABS is not fitted to the Grizzly 700 2016; bleeding is done at individual caliper bleeder valves.
  • The Grizzly uses a front dual-caliper system and a rear caliper; some models have twin front calipers sharing a master cylinder/reservoir.
  • ABS-style components are not present, so flush/bleed is straightforward but must be done on each caliper in sequence.
  • Power steering (EPS) does not affect the hydraulic brake system, but ensure the vehicle is OFF and steering is centered during service.
  • Stock reservoir is translucent plastic mounted under the front rack area — keep contaminants out and replace the cap seal if worn.

Safety first

  • Wear eye protection & gloves; brake fluid is corrosive to paint and irritating to skin.
  • Keep fire sources away; brake fluid is flammable.
  • Dispose of used fluid per local regulations.

Preparation

  1. Park ATV on level ground, engage parking brake, and block wheels.
  2. Clean the reservoir cap area thoroughly to prevent contamination when opened.
  3. Remove reservoir cap & diaphragm. If the reservoir has a filter or screen, inspect and clean it. Do not let dirt fall in.
  4. Use a turkey baster or syringe to remove most of the old fluid from the reservoir; leave a small amount to keep the master cylinder primed.
  5. Top up with fresh DOT 4 fluid to the specified level. Do not mix DOT types; if unsure, use fresh DOT 4 and flush completely.

Bleeding sequence

Follow this sequence for best results: start with the caliper furthest from the master cylinder and finish with the nearest. On the Grizzly 700 that is typically: rear caliper, then right front, then left front. Confirm by visual inspection of hydraulic lines to the master cylinder for exact routing.

Dry (single-person) bleed method

  1. Attach clear bleed hose to the bleeder nipple on the selected caliper, place the other end in a catch container partially filled with fresh fluid to prevent air re-entry.
  2. Crack the bleeder nipple about 1/4 turn using the correct wrench.
  3. With the reservoir topped to safe level, pump the brake lever slowly and hold it under firm pressure. While holding, open the bleeder for a second to let fluid/air escape, then close the bleeder before releasing the lever. Repeat until no air bubbles appear in the hose and the lever feels firm.
  4. Keep reservoir topped during the process to avoid drawing air into the system.
  5. Tighten bleeder to specified snugness; avoid over-torquing. Wipe any spilled fluid immediately with brake cleaner.
  6. Repeat for the remaining calipers in sequence (rear, right front, left front).

Two-person (recommended) bleed method

  1. Partner sits on the machine and repeatedly applies and holds light pressure on the brake lever when asked.
  2. Open the bleeder nipple to let fluid/air escape, then close while the lever is still held. Repeat until clear fluid with no bubbles flows.
  3. Keep reservoir topped between cycles.
  4. Proceed caliper-by-caliper in the same far-to-near sequence.

Flush & complete replacement (full system bleed)

  1. If you are replacing all fluid, remove as much old fluid from the reservoir as possible, then add fresh fluid.
  2. Perform the bleeding sequence until the fluid exiting each caliper runs clear and matches the new fluid color.
  3. After final bleed, ensure reservoir is filled to the correct mark, reinstall diaphragm & cap securely.
  4. Clean and torque any loosened components to spec. Wipe all brake fluid off painted surfaces and apply light corrosion protectant to metal parts if needed.

Benchmarks & checks

  • Lever feel: firm and consistent with rise that does not creep when held under pressure.
  • No sponginess or travel that includes compressibility of the lever.
  • Inspect brake lines for cracked or swollen hose sections — replace if suspect.
  • Check pad thickness and rotor condition while caliper is accessible; replace pads or resurface rotors as required.
  • Test brakes at low speed in a safe area before normal operation.

Common issues & model-specific tips

  • Leaking bleeder valves: clean threads and seating area before opening. Replace a bleeder that won’t seal.
  • Contaminated reservoir cap seal: replace if brittle to prevent moisture ingress. The Grizzly reservoir location is exposed to the elements more than passenger cars, so seals can age quicker.
  • Brake line routing: inspect line clamps and routing points around racks & frame on the Grizzly to ensure no chafing when steering or suspension cycles.
  • Electrical EPS components: do not submerge EPS connectors while working near the front; protect electricals from spilled fluid.

Aftercare

  1. Double-check reservoir level after a short test ride; top off if needed.
  2. Reinspect bleeder nipples for leaks after initial use.
  3. Record the service date and fluid type in your maintenance log; brake fluid should be replaced every 2 years or per Yamaha schedule, sooner if exposed to heavy use or water contamination.

Performing a full brake fluid change on your 2016 Yamaha Grizzly 700 4X4 EPS keeps stopping power reliable & protects internal components from corrosion. If you prefer professional service or find persistent problems after bleeding, visit a qualified ATV technician.
