Replace the front brake lines.
Use an 11-mm line wrench on the hard line
nut and a 16-mm wrench on the flats on the
flex line hose-end.
Remove the stock flexible line from the hard
line and completely remove the stock caliper
and line from the vehicle.
Install the copper washer onto the new line
as shown.
Install the new flexible line, with washer using
the stock spring clip under the hard line nut
and clean with brake clean once tightened.
Install the rubber brake line grommet into the
factory bracket on the back of the upright.
Re-connect all ABS sensor wires and the
brake pad wear sensor.

Make sure that the brake rotor spins freely
and that the rotor is flush on the hub.

Bleed the brakes using fresh high-quality
brake fluid. A power bleeder is highly
recommended. Two bleeders are on each
front caliper.
Bleed the outers first until no air exits, then
the inners until no air exits
Wait 10-15 minutes.
Power bleed again while turning the ignition
on/engine off and stroke the brake pedal five
times when each bleeder is open. This
process will assure a proper bleed with the
ABS equipped system.
Tighten all bleeders securely.

Clean all brake line connections with brake
cleaner and compressed air so that they are
clean and dry. Start engine and pressurize
brake system several times and check for
leaks at all the brake line connections.
Correct any leaks before driving the car.

Check the clearance between the wheels and
the new brake calipers. Make sure that there
is at least 1/8"(0.125") between the wheel
and the caliper.
