This MotoSport guide walks you through safely flushing and bleeding the hydraulic brakes on a 2018 Textron Alterra VLX 700 EPS. Follow every step carefully, work in a clean area, and inspect components as you go. If you’re not comfortable with brake work, have a qualified technician complete the job.
What you need
- Clean brake fluid (DOT4 recommended; verify owner’s manual for DOT3 vs DOT4 compatibility)
- Clear plastic tubing that fits snugly over each brake caliper bleeder nipple
- Catch bottle partially filled with clean brake fluid
- Box wrench set for bleeder nuts and caliper hardware
- Screwdriver or small tool to open reservoir cover (clean rag under cap)
- Rubber gloves, safety glasses
- Shop rags and isopropyl alcohol for cleanup
- Optional: vacuum or pressure bleeder, or second person for pump-and-hold method
Notes specific to the 2018 Alterra VLX 700 EPS
- The master cylinder reservoir is located at the right handlebar master cylinder assembly; keep the reservoir cap and diaphragm clean to avoid contamination.
- This machine uses hydraulic disc brakes front and rear. There is no ABS; bleeding follows standard hydraulic procedures.
- Power steering (EPS) is separate from the brake system but always place the machine in gear/park and block wheels before working on brakes.
- Brake hoses and caliper mounting bolts on this model can corrode in wet environments; inspect slide pins, bleeder nipples and banjo fittings for damage or leakage.
- Always avoid spilling brake fluid onto plastic body panels or painted surfaces — it can cause damage. Wipe spills immediately and rinse with water if needed.
Preparation
- Park on level ground, put transmission in park/neutral and engage parking brake. Block wheels.
- Clean around the master cylinder reservoir cap thoroughly to prevent dirt contaminating fluid. Remove the cap and diaphragm. Top up with new brake fluid so the level is between min and max but don’t overfill.
- Locate bleeder nipples on each caliper and clean around them. Place a clear hose over the nipple and submerge the other end in the catch bottle that contains fresh fluid to prevent air re-entry.
- If using a pressure or vacuum bleeder, attach per manufacturer instructions to the reservoir or caliper respectively.
Bleeding sequence
Bleed the caliper farthest from the master cylinder first, then proceed progressively to the closest. On the Alterra VLX 700 EPS that typically means: rear caliper(s) first (farthest), then front calipers, finishing at the caliper closest to the master cylinder/master cylinder port. If unsure, identify which caliper has the longest hydraulic line to the master cylinder and start there.
Two-person pump-and-hold method
- Person A slowly squeezes the brake lever/pedal several times and then holds firm pressure.
- Person B cracks the bleeder nipple about 1/4 turn until fluid and air bubbles run into the hose, then tightens the nipple before Person A releases the lever/pedal.
- Repeat until clear, bubble-free fluid flows and the lever/pedal feel is firm. Keep the reservoir topped up during the process to avoid drawing air into the system.
One-person or pressure/vacuum bleeder method
- Attach your pressure bleeder to the reservoir or use a vacuum pump at each bleeder nipple in turn.
- Operate the tool until fluid runs clear from the hose with no bubbles. Move to the next caliper following the farthest-to-nearest sequence.
- Monitor reservoir level and never let it drop below the minimum while bleeding.
After bleeding each caliper
- Tighten bleeder nipple to a snug fit. Clean any fluid from the nipple and surrounding area.
- Top off reservoir to the correct level, reinstall diaphragm and cap, and secure.
- Repeat for remaining calipers following sequence.
Final checks
- Cycle the brake lever/pedal to confirm a firm, non-spongy feel. If soft, repeat bleeding steps until firm.
- Check for leaks at banjo fittings, bleeder nipples and hose connections while a helper applies pressure.
- Inspect caliper mount bolts and slide pins; torque to factory specs if you remove hardware (consult your service manual for exact torque values).
- Dispose of used brake fluid properly at a permitted recycling center.
- Test ride slowly in a safe area to confirm braking performance before normal operation.
Common issues & maintenance tips
- If brakes continue to feel soft after thorough bleeding, inspect caliper pistons and seals for contamination or corrosion; rebuild or replace as needed.
- Replace brake hoses if cracked, swollen or leaking; they can trap air and degrade performance.
- Service the system every 1-2 years depending on use and storage conditions to prevent moisture buildup in fluid and corrosion of components.
Performing a proper brake fluid flush and bleed on your Alterra VLX 700 EPS restores pedal/lever firmness and safety. Keep records of service intervals and fluid type used for future maintenance.
