This MotoSport-exclusive guide walks you step-by-step through replacing and bleeding the hydraulic brake system on the 2018 Textron Alterra 700XT EPS so you can restore firm pedal feel and reliable stopping performance. Instructions are tailored to the Alterra 700XT EPS layout and components; follow them exactly and observe all safety precautions.

What you'll need

  • DOT 4 brake fluid (always use fresh, unopened fluid)
  • Clear plastic tubing that fits snugly over bleed nipples
  • Brake bleeder bottle or clean catch container
  • Hand pump or one-person vacuum bleeder (optional)
  • Open-end wrenches sized for bleed nipples (usually 8 mm or 10 mm)
  • Turkey baster or fluid syringe
  • Clean rags, brake cleaner, disposable gloves, safety glasses
  • Jack or ramps and stands to lift the ATV if wheel access is needed
  • Small funnel and a clean, lint-free funnel screen or filter

Model-specific notes for the 2018 Alterra 700XT EPS

  • The 700XT EPS uses a non-ABS hydraulic brake system with front dual discs and a rear disc; master cylinder reservoirs are accessible under the front rack and near the rear brake lever depending on configuration. Confirm reservoir locations before starting.
  • Power steering (EPS) is electrical and unrelated to the brake hydraulic system, but avoid splashing brake fluid on EPS wiring connectors and harnesses.
  • Brake line routing on the Alterra is compact; don't kink or twist lines when moving calipers or turning wheels during bleeding.
  • Textron recommends DOT 4 fluid for best performance in varying temperatures; do not mix DOT 5 silicone fluid with DOT 4/3 systems.
  • If the vehicle has high-mileage or contaminated fluid, do a full system flush front and rear. For annual maintenance, replacing fluid every 1-2 years is a good MotoSport practice.

Safety first

  • Work on a level surface with the engine off and key removed.
  • Wear eye protection & gloves; brake fluid is corrosive to paint and plastic.
  • Keep the master cylinder reservoirs topped with fresh fluid throughout bleeding to prevent air being drawn into the system.
  • Dispose of used brake fluid per local hazardous-waste rules; do not pour down drains.

Preparation

  1. Park the ATV on level ground, chock the wheels, and secure it so it won't roll.
  2. Locate both brake master cylinder reservoirs (front and rear). Clean the caps and surrounding area to prevent contamination when opening.
  3. Remove reservoir caps and diaphragms. Use a turkey baster to remove most old fluid from each reservoir, leaving a small amount to protect seals.
  4. Top reservoirs with fresh DOT 4 fluid. Keep caps loosely in place to avoid contamination while working.
  5. If you plan to lift wheels, support the ATV on stands so wheels and calipers are accessible. Do not rely on the jack alone.

Bleeding order (recommended)

Bleed the brakes starting from the caliper furthest from the master cylinder and work toward the closest. For the Alterra 700XT EPS the typical sequence is:

  1. Right rear (if applicable)
  2. Left rear
  3. Right front
  4. Left front

Step-by-step bleeding & fluid replacement

  1. Attach clear tubing to the first bleed nipple and submerge the other end in a catch bottle partially filled with clean brake fluid to prevent air re-entry.
  2. Have an assistant slowly depress the brake lever or pedal 2-3 times and then hold it down. If you're one person, use a one-person vacuum bleeder or hand pump that replaces the assistant.
  3. With the lever held down, open the bleed nipple one-quarter to one-half turn until fluid and air bubbles flow into the tubing. Close the nipple before the assistant releases the lever. Repeat until only clear fluid without bubbles flows.
  4. Top off the corresponding master cylinder reservoir after each cycle to ensure air is not drawn in. Always keep the reservoir cap off but close to prevent contamination.
  5. Move to the next caliper in the bleeding sequence and repeat steps 1-4 until all calipers are bled and clear fluid runs from each bleed nipple.
  6. Once all calipers are bled, operate the brake lever/pedal several times to confirm firm feel. If sponginess remains, repeat the full sequence; trapped air can hide in lines or caliper pistons.
  7. When satisfied, tighten all bleed nipples to spec snugness (do not over-torque), clean fluid from components with brake cleaner, and reinstall reservoir diaphragms and caps.
  8. Lower the ATV, test brakes at low speed in a safe area to confirm firm, consistent braking before returning to normal use.

Special tips for the Alterra 700XT EPS

  • If a caliper piston is stuck and prevents proper bleeding, remove the caliper and carefully free or reinstall pistons before re-bleeding.
  • The compact master cylinder reservoirs can allow fluid to overflow into nearby wiring if overfilledtop carefully and clean any spills immediately.
  • When pushing pistons back into calipers during pad service, cover the brake lever to prevent fluid spillage from rapidly overflowing the reservoir.
  • If you encounter stubborn air, tilt the ATV slightly (following safety procedures) or cycle steering through full lock to move trapped air toward bleed nipples on the front lines.

Final checks

  • Confirm no leaks at bleed nipples, hoses, banjo bolts, or master cylinder seals.
  • Brake lever/pedal should be firm with minimal free play. Adjust free play per owner manual if required.
  • Record fluid change date and mileage for future maintenance scheduling.

Following this MotoSport-specific procedure will ensure a clean, complete brake fluid change and reliable braking on your 2018 Textron Alterra 700XT EPS. If you encounter persistent issues such as collapsed hoses, seized calipers, or internal master cylinder leaks, consult a trained technician or contact MotoSport parts specialists for replacement components.
