B) Remove pinch bolt nut
NOTE: Do not allow bolt to back out or
turn. Remove nut, then remove bolt.
Pull down gently on steering arm thus
removing from upright
8 Remove the Upper Front Control Arm
nut and bolt.
Carefully pull up on control arms, thus
removing from upright
NOTE: The slits in the upright must not
be widened using a chisel or similar
tool! This can cause the pinch arms to
crack. If the control arm pins are stuck
in the housing, tap lightly with a rubber
mallet on the bottom of the control
arms.
9 Peel back on rubber seal and remove
Now remove plastic cover to reveal
control arm girdle bolts

brackets and rubber bushings (these
will be re-used with the STaSIS
ARB).
OEM ARB bushings have enough
flex to accommodate the STaSIS
ARB.

13 of 28
11 Install STaSIS ARB into vehicle. It
may be necessary to deflect the
upper control arm by gently using a
pry bar as shown to facilitate the
installation.
12 Once located, installation is the
reverse of all removal steps. Make
sure to locate drop link bolts into the
ARB before tightening the ARB
Mounting Bracket bolts. Torque all
fasteners to the specifications
shown.
*NOTE*: After mounting to the
vehicle, make sure your ARB is
centered between the two clamps to
avoid possible binding and
interference with suspension
components during vehicle
operation.

Note –
Bonded rubber suspension bushings can only be turned to a limited extent. The
mounting bolts of the suspension links must only be tightened when the suspension is
compressed to the curb weight position.
10 Install wheels and tighten. Lower the car onto its wheels and torque all wheel lug bolts
to the recommended torque.
Note: Check wheel alignment after suspension installation

Installation Guidelines
•Torque all fasteners to specification. Do not use an impact wrench.
•The rotors are side-specific, rotational direction is labeled. Open portion of crescents face toward the
direction of rotation.
•The rotors have been dynamically balanced by machining the outer edge. Flat spots along the outer
diameter are normal and will not affect the performance of the rotor.
•Tighten hydraulic connections with a line wrench.
•Bleed brakes properly to assure proper brake operation; the use of a power bleeder is
recommended.
•Ensure all ABS sensor and Pad wear sensor plugs are reconnected.

18 of 28
•Proper pad bedding is essential to proper brake operation.
•Initially drive the car with low braking force to check brake operation; then follow all steps listed in the
bedding process outlined at the end of this instruction manual.
•During bedding do not thermally shock the rotors with aggressive braking before the rotors have come
up to temperature. Cracks on new rotors can form due to thermal shock. Gradually increase brake
pressures as instructed in the bedding procedure.
•After bedding brakes re-torque wheel nuts to proper torque specifications.
•If vibration occurs during normal usage, check for abnormal pad wear deposits on the rotor. Double
check all fasteners and repeat the bedding process 2-3 cycles until the pad deposits on the rotor
becomes uniform.
•If the vehicle is driven in adverse weather conditions, STaSIS Engineering recommends annual
cleaning and inspection of the rotor crescents. A common source of vibration can be attributed to dirt
completely filling in the crescents on the inboard side of the rotors which in turn will not allow the pad to
function properly.
•Brake rotor wall thickness wear limit is 1.0 mm per side of rotor. Rotor face runout limit +/- 0.010 in,
when taking measurement make sure rotor is tightened down to the hub at all 5 bolt locations.

Instructions
1 Sort the parts in the brake kit for the right
and left side. Brake bleeders face upward.
Caliper mounting brackets are universal.
Install brake pads in calipers.
Install brake lines with banjo bolt and crush
washers. Orient brake line facing straight
up as shown.
2 Raise vehicle and remove the front wheels.
3 Using brake cleaner, clean the brake line
connection at the body flange. Remove all
dirt and debris from this area and from the
line connection threads so that no dirt will
get into the new brake line when it is
installed.
4 Remove the caliper.
Remove the ABS sensor wire from the
holding bracket on the brake caliper to
facilitate removing the caliper.
Disconnect the brake pad wear sensor wire
from the driver’s side front brake inner pad.
Remove caliper mounting bolts (the bolts
holding the caliper mounting bracket to the
upright). Save these bolts as they will be
reused.
Remove caliper and support it so that the
brake line is not under tension.
5 Remove the brake rotor. Clean the hub,
removing all rust from the rotor mounting
surface, the rotor pilot and wheel pilot.
Apply some anti-seize to the pilot surface to
prevent rotors and wheels from sticking in
the future. Do not get any anti-seize on the
rotor mounting surface of the hub.

6 Install caliper mounting brackets using the
stock mounting bolts and torque to 92 ft-lb.
The bracket will mount to the outside face of
the upright with the machined pockets on
the bracket going against the upright. The
OEM bolts will fit through the upright from
the backside and thread into the bracket.
7 Install the new rotors making sure they are
free of dirt and grease. Tighten the rotor
retaining bolt to 48 in-lbs.
8 Place the caliper with the brake pads
installed onto the caliper mounting bracket
and install the caliper mounting bolts M12 x
1.75 x 60 and torque to 70 ft-lb. If the
caliper will not go over the rotor because
the pads are too close together, push the
pads back using a pad spreader.
Note: When rotating, the rotor must
always pass the small caliper piston first.
Therefore in a trailing caliper application like
we have here the small caliper piston will be
at the bottom of the caliper. The purpose is
to insure even pad wear.
