This MotoSport service guide covers a full brake fluid change and bleed for the 2019 Textron Alterra 700XT EPS. Follow these steps carefully to restore firm pedal feel and remove moisture and air from the hydraulic system. This procedure is written for the OEM hydraulic disc system on the Alterra 700XT EPS; always reference your factory service manual for torque specs and model-specific diagrams before starting.

Tools & Materials (MotoSport recommended)

  • DOT 4 brake fluid (fresh, unopened)
  • bleeder wrench or correct-size hex/open-end wrench
  • clear vinyl tubing and catch bottle
  • hand vacuum pump or pressure bleeder (optional, speeds the job)
  • clean lint-free rags, small brush, isopropyl alcohol
  • jack and stands or ATV lift
  • safety glasses & nitrile gloves
  • service manual for torque values

Important Model Notes for the Alterra 700XT EPS

  • The Alterra 700XT EPS uses DOT 4 hydraulic fluid from the OEM master cylinder reservoirs. Do not mix DOT 4 with DOT 5 silicone fluid.
  • Electrical Power Steering (EPS) is present on this model. Bleeding brakes does not normally require EPS intervention, but avoid long periods of steering operation with the battery disconnected. If you disconnect the battery, follow the manufacturer procedure for EPS re-initialization if needed.
  • The brake reservoirs are plastic and typically use a diaphragm under the cap – keep them clean and reseal tightly to avoid contamination and moisture absorption.
  • Caliper banjo bolt torque and bleeder screw torque can vary; use the service manual values rather than guessing. If unsure, MotoSport parts specialists can help source the right hardware.

Preparation

  1. Work on a level surface. Block the ATV so it cannot roll. Chock wheels and/or put the ATV on a lift for safe access to calipers and lines.
  2. Clean around the brake fluid reservoirs and caliper bleeder screws with isopropyl alcohol and a brush to prevent contamination.
  3. Remove the reservoir cap(s) and diaphragm cover. Siphon or carefully draw off most of the old fluid from the reservoir, leaving some to prevent run-dry during bleeding.
  4. Inspect lines, hoses, banjo bolts and calipers for leaks or damage. Replace any cracked hose or leaking fitting before proceeding.

Bleeding Sequence

Use the caliper furthest from the master cylinder first, then work toward the closest. On most Alterra 700 layouts the typical order is: rear caliper, front right, front left – but confirm location of the master cylinder on your machine and follow furthest-to-closest logic.

Bleed Procedure — Two-Person (Manual) Method

  1. Have an assistant sit on the ATV and apply light steady pressure to the brake lever or pedal when instructed.
  2. Attach clear tubing to the bleeder nipple and place the other end in a catch bottle partially filled with clean brake fluid (prevents air re-entry).
  3. Loosen the bleeder screw ~1/4 to 1/2 turn. Instruct assistant to slowly depress the lever/pedal until near the end of travel. While held down, tighten the bleeder screw. Release lever/pedal. Repeat until fluid runs clear and free of bubbles. Keep reservoir topped with fresh DOT 4 during the process.
  4. When clear, tighten the bleeder to the recommended snug torque (consult service manual), wipe fittings, and move to the next caliper in sequence.

Bleed Procedure — Vacuum or Pressure Bleeder (Recommended for one-person)

  1. Attach vacuum pump to bleeder nipple or attach a pressure bleeder to the master cylinder reservoir following the equipment instructions.
  2. If using a vacuum pump: apply vacuum, open bleeder nipple, allow fluid and air to draw out until clear, then close nipple before releasing vacuum.
  3. If using a pressure bleeder: pressurize reservoir to manufacturer-specified psi (do not exceed tool limits), open bleeders one at a time in the correct sequence until fluid is clear, then close each bleeder before moving on.

Refill & Final Checks

  1. Top the master cylinder reservoirs to the specified level with fresh DOT 4 fluid, replace diaphragms and caps, and secure them.
  2. Pump the brake lever/pedal several times with engine off to confirm firm, consistent feel. If sponginess remains, repeat bleeding until firm.
  3. Inspect all fittings for leaks at bleed screws, banjo bolts and hoses while applying steady brake pressure.
  4. Torque banjo bolts and caliper hardware to factory specs from the service manual.
  5. Properly dispose of used brake fluid at a hazardous-waste facility — do not pour down drains or on the ground.

Troubleshooting

  • Persistent soft pedal: recheck bleed order, ensure reservoir never ran dry, inspect master cylinder for internal seal leaks.
  • Air keeps appearing: check for leaking hose, loose banjo bolt, or cracked hose; replace defective component and repeat bleed.
  • Contaminated fluid (dark, oily): fully flush system and replace rubber hoses if they show swelling or deterioration.

Safety & Best Practices

  • Use only DOT 4 fluid specified for the vehicle. Mixing different DOT fluids can degrade performance.
  • Avoid getting brake fluid on painted surfaces; it will strip paint. Rinse immediately with water and wipe dry if contact occurs.
  • Perform a low-speed test ride in a safe area to verify braking performance before normal use.
  • Regularly inspect brake lines and fluid level; brake fluid is hygroscopic and should be replaced every 1-2 years depending on use and climate.
