This MotoSport guide walks you step-by-step through flushing and bleeding the brake system on a 2005 Suzuki Twin Peaks 700 4X4. Follow these steps carefully to restore firm pedal/lever feel and remove moisture and contaminants from the system.
What you’ll need
- DOT 3 or DOT 4 brake fluid (check your OEM cap for recommendation; both types are compatible but do not mix with silicone-based fluids)
- Clear hose that fits over bleed nipple
- Brake fluid catch bottle or clear container
- Box wrench set (for bleed nipples)
- Screwdriver, pliers, rags, rubber gloves and safety glasses
- Floor jack or ATV lift and stands (if needed)
- Turkey baster or syringe for removing old fluid from master cylinder reservoir
- Vacuum bleeder or a second person to operate the brake lever/pedal
Safety and model notes
- The Twin Peaks 700 has front and rear hydraulic brakes with exposed brake lines and a plastic master cylinder reservoir on the handlebar area and rear brake master near the foot lever depending on configuration — clean the reservoir cap area before opening to prevent dirt contamination.
- Brake fluid is hygroscopic & will absorb moisture over time; replace every 1-2 years if used regularly or when you detect spongy brakes.
- Avoid getting brake fluid on painted surfaces or plastic; it can damage finishes. Rinse spills immediately with plenty of water.
- The Twin Peaks does not use antilock components, so bleeding is straightforward but note any aftermarket modifications (ABS/valves) before proceeding.
Preparation
- Work on a level surface and secure the ATV. If wheels are removed for access, support the wheels and hubs safely.
- Clean the reservoir cap and surrounding area thoroughly. Remove the cap and diaphragm slowly to minimize fluid splash and contamination.
- Use a turkey baster or syringe to remove as much old fluid from the reservoir as possible. Wipe inside the cap and reservoir lip clean.
- Top the reservoir with fresh brake fluid to the recommended mark. Keep the cap loosely in place to reduce exposure to air between steps.
Bleeding sequence
Always start at the caliper farthest from the master cylinder and work toward the nearest. On many ATVs that means rear caliper first, then the front calipers (left/right) — however confirm which caliper is farthest from the master cylinder on your particular bike before starting. Repeat the sequence until clear, bubble-free fluid appears.
Two common bleed methods
Two-person (squeeze and open)
- Attach clear hose to the bleed nipple and submerge the hose end in a container partially filled with fresh fluid to avoid drawing air back in.
- One person slowly pulls the brake lever or depresses the pedal while the other opens the bleed nipple 1/4 turn. Fluid and bubbles will flow into the hose.
- Close the nipple before the lever/pedal is released to prevent air from returning. Repeat until no air bubbles appear and the fluid runs clear.
- Top up the reservoir frequently during the process to prevent it from running dry.
One-person (vacuum or pump-style bleeder)
- Connect the vacuum bleeder to the bleed nipple and the hose to the reservoir or catch bottle per the bleeder instructions.
- Open the nipple and run the vacuum until clear fluid without bubbles is drawn out.
- Top up the reservoir as needed; close the nipple, then move to the next caliper when complete.
Complete replacement (full flush)
- After you have bled each caliper once, drain remaining old fluid from the reservoir and refill with fresh fluid.
- Repeat the bleeding sequence for each caliper until the fluid coming out is the clean fluid you added and there are no bubbles.
- When finished, tighten bleed nipples to the torque you commonly use for small fittings (snug plus a small fraction — typically 8-12 ft-lbs; avoid over-torquing). Verify there are no leaks.
- Clean all spilled fluid, replace the reservoir cap and diaphragm, and wipe down calipers and lines.
Final checks
- Squeeze the lever and press the pedal repeatedly with the ATV on the ground – feel for firm, consistent resistance. If spongy, repeat the bleeding process.
- Inspect lines, hose clamps and caliper seals for leaks or aging cracks. Replace any soft or damaged hoses immediately; use OEM-spec or quality aftermarket lines.
- Test ride at low speed in a safe area to confirm braking performance before riding normally.
- Dispose of old brake fluid per local hazardous-waste regulations.
Model-specific tips for the 2005 Twin Peaks 700
- Master cylinder reservoirs on this model are plastic and can deteriorate; inspect for cracks and replace if cloudy or damaged to avoid contamination.
- Factory calipers and lines are straightforward to access but pay attention to routing near the steering and suspension to avoid pinching when wheels turn.
- If your Twin Peaks has aftermarket brake components, check manufacturer bleed procedures & recommended fluid type before flushing.
- Because this V-twin ATV can see mixed trail and utility use, inspect brake mounting bolts and carrier hardware for looseness after reassembly – vibration can work fasteners loose over time.
Performing a proper flush and bleed restores braking reliability and extends the life of brake components. If you’re not confident doing this maintenance yourself, MotoSport recommends professional service to ensure safe results.
