Brakes
The brakes on the Jabiru are lightweight purpose designed items but do require a little more attention than standard. They are not self-adjusting for wear and as such require periodic checking to ensure that they are in proper adjustment. I speak from experience in recently nearly ending up in a ditch (not in a Jabiru) because the brakes failed and I had no way to stop on an asphalt runway! Brake Pads Check your pads from time to time. If they are allowed to wear down to the rivets they will contact the disk and damage it. Pad replacement needs to be done using a proper brake pad riveting tool which can be used to cleanly remove old rivets and re attach pads to their respective backplates. Note that the long rivets are used for the aluminium backplate and the short ones to attach the pads to the steel backplate. Bleeding Brakes! When bleeding the brakes remove both brake calipers from the discs and use a small clamp to hold the slave piston in one one side. On the other side, hold the caliper up above the master cylinder with the piston and seal removed. Fill the master cylinder with brake fluid and slowly pump the brake. Be sure to keep the master cylinder topped up to prevent pumping air into the system. Pump the fluid up to the open cylinder until it is brimmed and no bubbles come out. Keeping the slave cylinder level insert the rubber brake seal in sideways and then rotate cup side in, trying to prevent air being trapped. Insert the steel piston and put a temporary clamp on it. Carry out the same procedure on the other side. It is helpful to tape some kitchen towel around each brake pipe to catch any spills.
