EPLACING
1. Install a clear hose on the top of the brake fluid reservoir and insert it in a
container to catch fluid overflow.
2. Attach a pump style oil can filled with hydraulic fluid to the bleeder valve on the
bottom of one of the brake calipers. Open the bleeder valve and pump the oil
can until clean fluid flows in the clear tube at the top of the fluid reservoir. Close
the bleeder valve and remove the oil can and hose.
3. Repeat the previous step on the other brake caliper.
4. Confirm that the brake pedal at each seat position for the left and right brake
systems feel firm with no sponginess when pressed. Also confirm that there are
no air bubbles visible in the translucent brake lines between the left and right
seat rudder pedals. If there is any sponginess or presence of air bubbles repeat
the flushing / replacing steps.
5. Use a syringe to slightly reduce the fluid level in the reservoir and reinstall the
reservoir cap.
