This MotoSport proprietary guide covers safe, effective brake fluid replacement and bleeding for the 2007 Can-Am Renegade 800 (REN800). Follow all steps carefully, wear eye protection and gloves, and refer to your service manual for torque specs and specific factory details when required.

Model notes – what to know about the 2007 REN800

  • The 2007 Renegade 800 uses hydraulic disc brakes with separate master cylinders for front and rear circuits. Verify whether your unit has combined or independent reservoirs before beginning.
  • Factory-specified fluid is typically DOT4. Confirm with your owner’s manual; do not mix DOT3/DOT4 with DOT5 (silicone) fluid.
  • The Renegade lacks ABS on most 2007 models, so bleeding is a conventional hydraulic process. If your machine has optional electronic components near reservoirs, take care to keep fluid off electrical parts.
  • Brake fluid is hygroscopic &mdash it absorbs moisture &mdash which degrades performance. Replace if dark, cloudy, or older than 2 years.
  • Brake fluid damages paint and plastics. Clean spills immediately with brake cleaner and fresh water.

Tools & supplies

  • DOT4 brake fluid (check manual to confirm)
  • Clear hose and catch bottle (marked for used brake fluid)
  • Wrenches for bleeder nipples (use correct size) and reservoir caps
  • Vacuum bleeder pump or 2-person assistant for hand-pump method
  • Clean rags, brake cleaner, gloves, eye protection
  • Hydraulic jack or ramps to access wheels (use jack stands)

Preparation

  1. Park on level ground, engage park brake, and disconnect the battery negative terminal if you will be working near electrical components.
  2. Raise the ATV and secure on stands so wheels with calipers are off the ground. Remove wheels if needed for access.
  3. Clean the reservoir caps and surrounding area to avoid contamination when opened.
  4. Inspect hoses, lines, calipers, and reservoir for leaks, swelling, or damage. Replace any damaged components before bleeding.

Reservoir locations & circuit identification

Identify the front and rear brake reservoirs. On the Renegade 800 the front master cylinder is typically on the right handlebar for the hand lever; the rear master cylinder is near the brake pedal with its own small reservoir. Treat each circuit separately.

Step-by-step: Replace fluid & bleed (recommended: vacuum or pressure bleeder one-person method)

  1. Open the reservoir cap(s) and remove the diaphragm or cover. Top up with fresh DOT4 fluid to the “MAX” level. Do not overfill.
  2. Start with the circuit farthest from the master cylinder and work toward the closest caliper. For front master cylinder: farthest caliper first. For rear circuit: follow same farthest-to-closest logic.
  3. Attach a clear hose to the bleeder nipple and submerge the other end in a catch bottle partially filled with fresh fluid to prevent air re-entry.
  4. If using a vacuum bleeder: connect pump to the caliper bleeder, open bleeder ~1/4 turn, pull vacuum until fluid runs clear without bubbles. Close bleeder while maintaining vacuum, then release vacuum and disconnect. Top the reservoir as needed between calipers to keep fluid above the minimum mark.
  5. If using the two-person push-pump method: have an assistant slowly depress the brake lever/pedal 3–4 times and hold it on the last press. Open the bleeder ~1/4 turn until fluid and bubbles flow out, then close the bleeder before the assistant releases the lever/pedal. Repeat until clear, then move to the next caliper. Always close the bleeder before release to avoid sucking air back in.
  6. Do not let the reservoir run dry at any time &mdash refill frequently. Running dry introduces air and requires repeating the entire circuit bleed.
  7. Continue until each caliper delivers clear fluid with no air bubbles and the brake lever/pedal feels firm and consistent.
  8. Tighten bleeder nipples securely (snug + small additional turn). Wipe all fluid from components and reinstall the diaphragm and caps on reservoirs.

Post-bleed checks

  • Lower the ATV, reinstall wheels if removed, torque lug nuts to spec, and torque any service fasteners per the manual.
  • Test brake lever and pedal travel with the ATV stationary &mdash they should be firm and not spongey. If soft, repeat bleeding until firm.
  • Road-test at low speed in a safe area. Confirm consistent braking, no pulling, and no leaks under load.
  • Properly dispose of old brake fluid according to local hazardous-waste rules.

Tips & cautions

  • Always use the specified fluid. Mixing fluids or using silicone DOT5 on a DOT system will damage seals and impair braking.
  • If braking remains soft after careful bleeding, inspect calipers for seized pistons or collapsing hoses and inspect the master cylinder for internal leaks.
  • Keep brake fluid containers sealed and fresh; fluid absorbs moisture rapidly once opened.
  • If you are not confident or you detect mechanical faults, have a qualified ATV technician complete the job.
