This MotoSport-exclusive guide walks you through a safe, thorough brake fluid replacement and bleeding procedure tailored for the 2018 Textron Alterra VLX 700. Follow every step carefully, use proper PPE, and perform the job on a level surface. If you're unsure at any point, stop and consult a qualified technician.

Quick model notes — what Alterra VLX 700 owners should know

  • The Alterra VLX 700 uses hydraulic front and rear disc brakes with separate master cylinders for front (handlebar) and rear (frame-mounted) systems. There is no factory ABS on the stock VLX 700.
  • Brake fluid reservoirs are small plastic reservoirs located at the front master cylinder on the handlebars and the rear master cylinder near the right-side frame area. Access may require removing a small trim/cover on the front and moving the seat for the rear.
  • Always confirm the DOT rating and capacity in your owner's manual before starting. Many Textron/Arctic Cat derived units use DOT 4, but verify for your specific machine.
  • Brake lines on older VLX 700s can show age-related swelling. Inspect lines, hoses, fittings & caliper boots while you have the system open. Replace any soft, cracked, or leaking components before bleeding.

Tools & supplies

  • Appropriate brake fluid (confirm DOT spec in owner's manual)
  • Clear 1/4" or 3/16" hose for bleeder nipples
  • Catch bottle or brake fluid reservoir bottle
  • Brake bleeder wrench or correct-size open wrench
  • Hand vacuum or pressure bleeder (optional but speeds the job)
  • Turkey baster or fluid syringe (for removing old fluid from reservoirs)
  • Clean rags, gloves, safety glasses
  • Small flat screwdriver to remove reservoir caps & diaphragms
  • Torque wrench for any fasteners disturbed

Preparation

  1. Park the ATV on a level surface, engage park/engine off, remove key, and disconnect the battery negative if you'll be working near electricals.
  2. Clean around reservoir caps thoroughly to prevent contamination. Remove the caps and the rubber diaphragm carefully and set aside on a clean rag.
  3. Siphon as much old fluid as possible from each reservoir into a waste container using a turkey baster or syringe. Do not allow dirt in.
  4. Top reservoirs with fresh brake fluid to prevent air ingress. Do one system at a time (front then rear, or follow your owner's manual). Keep the reservoir filled during bleeding.
  5. Inspect hoses, calipers, lines, and fittings for damage or leaks. Replace suspect parts before bleeding.

Bleeding sequence & method

Standard recommended sequence: start with the caliper farthest from the master cylinder and work toward the closest. For the Alterra VLX 700 that commonly means:

  • Front brake system: right front caliper (if machine is right-hand drive reference) then left front. If uncertain, pick the caliper farthest from the handlebar master cylinder first.
  • Rear brake system: if a single rear caliper, bleed that after the front system is complete.

Option A – Pressure bleeder (recommended for a clean job)

  1. Attach the pressure bleeder to the reservoir per tool instructions. Pressurize to the recommended psi.
  2. Open the farthest bleeder nipple slightly and allow fluid and air to purge into the catch bottle until clear, then tighten the nipple. Repeat for each caliper in sequence.
  3. Keep reservoir filled to prevent drawing air. Cycle the pump pressure briefly at the end to ensure no air remains, then tighten bleeder nipples to spec.

Option B – Manual pump & one-person method

  1. Attach the clear hose to the bleeder nipple and submerge the other end in a bottle partially filled with fresh fluid to prevent air return.
  2. Have an assistant slowly pump the brake lever or pedal 6–8 times and hold pressure on the lever/pedal.
  3. Open the bleeder nipple about 1/4 turn until fluid runs; close nipple before the assistant releases the lever/pedal. Repeat until no bubbles appear and the fluid is clear.
  4. Top off the master cylinder reservoir between cycles to avoid drawing air.

Option C – Vacuum bleeder

  1. Attach vacuum tool to the bleeder nipple and draw while pumping the lever/pedal or having an assistant pump. Continue until clear, then close nipple and move to next caliper.

Tips & torque

  • Always close bleeder nipples before the lever/pedal is released to avoid sucking air back in.
  • Wipe any spilled brake fluid immediately. Brake fluid damages paint and some plastics. Keep rags handy.
  • Bleeder nipple torque is light – snug to stop leaks, then a small additional fraction of a turn. Use a torque spec from the service manual where available; if not listed, do not overtighten less than 10 ft-lb on small bleeders is common practice.
  • After bleeding, pump the lever/pedal until it feels firm. If soft or spongy, re-check for air and repeat bleeding.

Finishing steps

  1. Top reservoirs to the correct level, reinstall diaphragms and caps securely.
  2. Clean all fittings, remove tools, and wipe any spilled fluid.
  3. Reinstall any covers/trim removed for access. Reconnect battery negative if disconnected.
  4. Test brakes at low speed in a safe area to confirm firm feel and proper stopping. Check for leaks after initial test rides and again after 24 hours of use.
  5. Dispose of used brake fluid following local hazardous waste regulations.

Common problems & troubleshooting

  • Persistent spongy lever/pedal: usually trapped air or contaminated fluid – repeat full bleed and inspect for leaks.
  • Fluid level dropping quickly: inspect for leaks at calipers, lines, and master cylinder seals.
  • Soft pedal that returns to firm after riding: may indicate worn pads or overheating; inspect pads and rotors for wear and glazing.

Final reminders specific to the VLX 700

  • Confirm exact DOT rating in your owner's manual before purchasing fluid; using the wrong fluid can damage seals and compromise safety.
  • The VLX 700's handling and carrying loads can amplify brake wear. Inspect pads and rotor condition while you have wheels off or during bleeding.
  • If you find any corroded or swollen hoses, replace them with OEM or quality replacement lines sized for the VLX 700 to maintain braking performance and safety.

Performing a full brake fluid replacement and bleed on your 2018 Textron Alterra VLX 700 will restore pedal/lever feel and ensure reliable stopping power when done carefully. When in doubt, contact a certified ATV technician.
