This MotoSport procedural guide covers step-by-step brake fluid replacement and bleeding for the 2011 Suzuki King Quad 750AXi 4X4 POWER STEERING (MMY: SUZUKI;KINGQD750P;2011). Follow safety precautions, use the correct fluid, and keep the work area clean to avoid contamination.
Notes specific to the 2011 King Quad 750AXi
- The brake system is a conventional hydraulic system with individual calipers on front and rear. There is no factory ABS on this model.
- Check the master cylinder cap or owner's manual for the manufacturer-specified fluid type. Use DOT-specified fluid only (see cap/label & manual). If uncertain, DOT 3 or DOT 4 is commonly used but confirm before proceeding.
- Power steering components are separate. Avoid spilling brake fluid on plastic reservoirs, power steering lines, or painted surfaces – brake fluid is corrosive to some plastics and paint.
- Brake lines on older ATVs can be brittle. Inspect hoses, banjo bolts, and clamps for corrosion or cracking while servicing.
Tools & supplies
- Correct brake fluid (manufacturer-recommended DOT type)
- Clear vinyl tubing that fits snug over bleeder nipples
- Catch bottle for old fluid
- Box or wrench set to fit bleeder nipples and master cylinder cap
- Brake bleeder wrench or screwdriver (as required)
- Hand vacuum pump or pressure bleeder (optional but speeds thorough bleeding)
- Turkey baster or syringe to remove old fluid from reservoir
- Clean rags, disposable gloves, and safety glasses
- Torque wrench (for caliper/banjo bolt reassembly if removed)
Preparation
- Park the ATV on level ground, set the parking brake, and remove the key.
- Clean around the master cylinder reservoir cap to prevent dirt contamination.
- Wear gloves & safety glasses. Keep rags handy to immediately wipe spills.
- If the fluid is very dark or contaminated, plan to flush the entire system starting at the master cylinder.
Step 1 – Remove old fluid from the reservoir
- Unscrew the master cylinder reservoir cap. Note any rubber diaphragms or foam inserts — set them aside in a clean area.
- Use a turkey baster or syringe to remove as much old fluid as possible from the reservoir. Dispose of old fluid properly.
- Wipe the reservoir clean with lint-free rags. Refill reservoir to the "MAX" mark with fresh brake fluid.
Step 2 – Identify bleed order
For optimal bleeding, work from the caliper farthest from the master cylinder toward the closest. Typical sequence for King Quad 750AXi:
- Rear caliper (if single rear axle caliper, start there)
- Front calipers, starting with the farthest side from the master cylinder
Confirm which caliper is farthest from the master cylinder visually; follow that sequence.
Step 3 – Bleeding method options
Use one of the following methods:
- Manual two-person method: one person pumps brake lever/pedal; the other opens/closes bleeder.
- One-person vacuum or pressure bleeder: vacuum from bleeder nipple or pressurize reservoir with a pressure bleeder for single-person operation.
Step 4 – Manual two-person bleeding procedure
- Attach clear tubing to the bleeder nipple and place the other end in a catch bottle partially filled with fresh fluid to prevent air re-entry.
- Have your helper slowly pump the brake pedal or lever several times, then hold pressure (do not lock it fully if uncomfortable).
- Open the bleeder nipple about 1/4 turn until fluid flows with visible bubbles into the tubing; close the nipple before the helper releases the pedal/lever.
- Repeat pump & open cycles until the fluid runs clear with no air bubbles. Keep the reservoir topped up to prevent running dry.
- Work through each caliper in the chosen sequence. After the final caliper is bled, go back to the first caliper and recheck for air until no bubbles appear anywhere.
Step 5 – Vacuum or pressure-bleeding procedure
- Follow the tool manufacturer's instructions. Typically, either draw fluid from bleeder nipples using a vacuum pump (open nipple, draw until clear) or connect a pressure bleeder to the reservoir and open bleeders sequentially from farthest to closest.
- Monitor reservoir level constantly to avoid drawing air into the master cylinder.
Step 6 – Final checks & reassembly
- Tighten bleeder nipples to factory snugness. If you removed banjo bolts or calipers, torque those fasteners to manufacturer specs; if you don't have specs, tighten to a firm, leak-free fit and consult a torque chart or dealer for exact values.
- Clean any spilled brake fluid off paint or plastic immediately with water and mild soap. Brake fluid can damage finishes.
- Top reservoir to the MAX mark, replace diaphragm and cap, and secure tightly.
- Operate the brake lever or pedal several times to confirm a firm, consistent feel. If the lever feels spongy, repeat bleeding until solid.
- Inspect hoses, calipers, and fittings for leaks while applying pressure to the brake system.
Post-service checks
- Road-test at low speed in a safe area to verify braking response and pedal/lever firmness.
- Recheck fluid level after the test and inspect for leaks again.
- Proper disposal: used brake fluid is hazardous. Dispose at a local recycling center or hazardous waste facility.
Troubleshooting
- Persistent spongy brake feel after multiple bleeds could indicate: internal master cylinder seal failure, air trapped in a caliper or line, or collapsed/soft brake hose. Replace damaged parts as needed.
- If you see continuous fluid loss, locate and repair the leak before continuing to use the ATV.
Model-specific maintenance tips
- On this King Quad, inspect the front axle area and power steering lines while working. Power steering leaks can show as fluid around the frame; keep brake fluid away from power steering components to prevent confusion and contamination.
- Because this model sees utility use, inspect brake pads and rotor wear during service – aggressive loads or towing can accelerate wear.
- Keep a maintenance log with fluid change dates. Brake fluid absorbs moisture over time; replacing every 1-2 years is common practice depending on use and storage.
Safety reminders
- Never reuse drained brake fluid. Always use fresh, sealed brake fluid from a new container.
- Avoid mixing different DOT fluids unless recommended. Mixing DOT 5 (silicone) with DOT 3/4 is not compatible.
- If unsure about torque specs, bleed order, or any unusual condition, consult a qualified technician or MotoSport service advice.
Following these steps will help ensure reliable, responsive brakes on your 2011 Suzuki King Quad 750AXi 4X4 POWER STEERING. Regular inspection and using the correct fluid keep stopping performance consistent and safe.
