This MotoSport guide gives a step-by-step, model-aware procedure for flushing and bleeding the hydraulic brakes on a 2008 Yamaha Grizzly 700 4X4 EPS. Follow the safety notes and the bleed order to remove air, restore firm pedal/lever feel, and renew contaminated or aged DOT 4 brake fluid.
Safety & preparation
- Work on a level surface with the engine off, parking brake engaged, and key removed.
- Wear safety glasses and nitrile gloves. Brake fluid is corrosive to paint and plastics.
- Use DOT 4 brake fluid only. Do not mix with DOT 5 (silicone) or other incompatible fluids.
- Keep rags and a catch bottle under each bleed nipple. Clean connections before opening to prevent contamination.
- Do not let the master cylinder reservoir run dry while bleeding — this will reintroduce air.
Tools & materials
- DOT 4 brake fluid (fresh)
- Clear tubing sized to bleed nipples and a catch bottle
- Brake bleeder wrench or appropriately sized open wrench
- Hand vacuum pump bleeder or helper for two-person method
- Shop towels, gloves, and a small funnel or syringe
- Torque wrench (for caliper bolts if removed)
Model-specific notes for the 2008 Grizzly 700 4X4 EPS
- The Grizzly 700 uses DOT 4 hydraulic brake fluid. The front master cylinder is on the handlebar; the rear master cylinder/reservoir is mounted near the rear brake assembly. Identify which reservoir feeds which caliper before beginning.
- Electric Power Steering (EPS) components are separate from the brake system, but avoid spraying fluid near EPS electrical connectors or steering sensor housings. Clean any spilled fluid immediately.
- Some 2008 Grizzly models have dual front calipers. If your unit has duals, bleed both front calipers individually following the farthest-first rule below.
- Reserve time for inspection: while bleeding, inspect hoses, banjo fittings, master cylinder seals, and caliper pistons for leaks or deterioration.
Bleed order (farthest-first principle)
Always start with the caliper farthest from the corresponding master cylinder and work toward the master cylinder:
- If master cylinder is the handlebar/front reservoir: bleed rear caliper first, then near-side front caliper, then far-side front caliper (or follow actual layout if reversed).
- If master cylinder feeds a specific caliper bank, identify left/right and nearest/farthest and apply the same farthest-first rule.
Step-by-step full fluid replacement and bleed
- Remove the reservoir cap(s) and clean around the cap to prevent dirt falling in. Use a small funnel or syringe to remove most old fluid from the reservoir; dispose properly.
- Top up reservoir with fresh DOT 4 until full. Keep the cap loose but covered to avoid contamination during the procedure.
- Position the ATV so you can access bleed nipples on each caliper. Place a catch bottle with clear tubing onto the bleed nipple and clamp or secure tubing to avoid backflow.
- Start at the farthest caliper (see bleed order). With a vacuum pump attached to the bleed nipple or with a helper ready at the brake lever/pedal, open the bleed nipple about 1/4 turn.
- Two-person method: Helper slowly applies steady pressure to the brake lever/pedal (not to full stroke, but firm) while you open the nipple. Close nipple before helper releases lever. Repeat until clear fluid with no bubbles flows and the lever/pedal feels firm. Keep the reservoir topped between cycles.
- One-person vacuum method: Operate the vacuum pump while opening the bleed nipple to draw fluid until clear and bubble-free. Close nipple, release vacuum, then move to the next caliper.
- Work through each caliper in order: farthest to nearest. For dual front calipers, bleed the far front caliper first, then the near front caliper, then the master cylinder area last.
- After each caliper is bled, tighten bleed nipples to spec (snug, then a small additional turn; do not over-torque). Wipe any spilled fluid immediately.
- Once all calipers are bled and the fluid is clear with no air, top the reservoir to the full mark and reinstall the cap securely.
- Test lever/pedal feel with the ATV stationary. The lever should be firm and not spongy. If spongy, repeat bleeding focusing on the circuit that still contains air.
Finishing checks
- Inspect all fittings, hoses, and master cylinder for leaks under light pressure and during a short low-speed test ride in a safe area.
- Verify brake performance at low speed before normal operation. Do not ride aggressively until you confirm braking is restored.
- Properly dispose of used brake fluid at a hazardous-waste facility or according to local regulations.
Troubleshooting & tips
- Persistent spongy feel after careful bleeding usually indicates remaining air in the system, a collapsing hose, a leaking seal, or a faulty master cylinderinspect and replace components as needed.
- If a caliper piston is seized or slow, remove caliper and free or service the piston before final bleeding.
- A brake fluid change interval of two years is a good preventive maintenance target for ATVs operating in varied conditions; sooner if you detect moisture contamination or poor performance.
Follow these steps and the model notes to complete a full brake fluid replacement and bleed on your 2008 Yamaha Grizzly 700 4X4 EPS. If you encounter damaged parts, incomplete bleeding, or uncertain issues, consult a qualified technician or bring your machine to MotoSport's service partners for professional inspection and repair.
