Replace Matco Brake Pads

Bleeding Matco Brakes
It should not be necessary to bleed the Matco brakes since the fluid reservoir provides that
function automatically. However, initially the brake system must be charged with brake fluid.
This is done using the same method described above for the Hegar brakes with the exception
that there is no bleeder valve on the master cylinder. This makes bleeding and filling the brake
lines easier. Simply pump brake fluid into one wheel cylinder until the fluid reaches the tee at
the back where the two wheel cylinder lines split. Then close that wheel caliper bleed line,
and repeat the same for the other wheel cylinder. As noted above, this time, continue pumping
until the fluid reservoir at the master cylinder outlet fills to the desired level. Note that
because the wheel caliper bleed ports are on the bottom of the caliper in their normal mounted
position, it is not necessary to rotate the wheel caliper to get the port on the bottom. Therefore,
that step is also eliminated compared to the Hegar brake procedure.
4.3.7 Replace Front Tire
Skill Level:
Owner, LSR-M, A&P
Tools:
1-1/8” wrench and socket, smooth flat bar,
½
” socket, hex wrench
Materials:
Replacement tire
Task Description:
The front tire can be replaced without any disassembly of any other elements of the carriage
following the procedure below.
1.
Chock rear wheels on both front and rear sides of both wheels. Raise the front wheel
about 12” off the ground. This is best done by setting a saw horse on each side of the
trike and laying a 2x4 or larger beam between them so that the 2x4 crosses the root
tube just in front of the front seat. Tie a rope to this board and then down under the
root tube and back up to the beam. Lift the front wheel to the desired height, tension
the rope, and tie it off. Be careful not to crush the wire harness or any tubing running
along the under side of the root tube. DO NOT support the carriage on the fiberglass
fairing. Also, be very careful not to lift the front of the trike too high with the wing off.
It will rapidly reach its balance point and flip onto the prop if lifted too high.
